コンテック Product Lineup

Generally, the "shipping inspection" that occurs during the manufacturing process of a product is a very important inspection that takes place just before the product is shipped to the market or the customer. Different companies may use different terms, but it is sometimes referred to as the "final inspection." For products, the judgment is made as "compliant" or "non-compliant," and for lots, it is judged as "pass" or "fail." There is a possibility that quality may deteriorate during subsequent packaging, transportation, and storage periods. *For more detailed information, please refer to the related links. Feel free to contact us for further inquiries.*

Next is the calibration of the "dew point meter" for measuring moisture content (dew point). In capacitive dew point meters, during dew point calibration, a dew point generation device is used to reproduce a desired dew point, and the sensor's sensing part, which is the device being calibrated, is actually exposed to that dew point environment for value assignment. Dew point environments are created for the number of measurement points specified by each manufacturer's calibration standards, as the values indicated by the sensor are not constant in relation to changes in the dew point. *For more detailed information, please refer to the related links. Feel free to contact us for further inquiries.

• Calibration and repair

What is the calibration of an "oxygen meter" that measures oxygen concentration? To perform calibration, it is necessary to first purge all the oxygen from the piping. Our company allows a period of two weeks for this, but when the purging is completed and it's time for calibration, any defects could lead to significant time loss, so it is essential to conduct an inspection before purging. In the case of electrochemical oxygen meters, many issues occur in the cell. *For more detailed information, please refer to the related links. Feel free to contact us for more details.*

• Calibration and repair

Calibration and adjustment are different. I will explain the differences between the two. Calibration refers to assessing the health status of measuring instruments. Since it only involves checking the condition, it does not include activities to improve the accuracy errors of the instrument or to fix any malfunctions. Adjustment, on the other hand, involves bringing the measurement values of instruments closer to the values of standard instruments or ensuring they fall within the accuracy range. 【Calibration of Measuring Instruments Possible by Contec】 ■ JCSS Calibration *Note (We provide business support) ■ Calibration requiring traceability ■ Calibration requiring certification ■ Repair and calibration of various instruments ■ Measurements or calibrations requiring high accuracy ■ Regular calibration *For detailed information, please refer to the related links.

As for the appearance inspection, we will pay attention to the same points as introduced with other products and carry out the work. For this product, the operation confirmation of the multiple LAN ports will be part of the inspection items, so we will actually verify the communication connection. As for the inspection method, we will use the network command "Ping" in the Windows command prompt. Ping is a command used to check whether there are any abnormalities in the communication path between two PCs. *For detailed content of the article, you can view it through the related links.

The main detection items for appearance defects through visual inspection include defects such as "foreign matter contamination in products or parts," "dirt," "discoloration," "scratches," "deformation," and "rust." The judgment of good or bad is made by comparing with standard sample products according to the condition. In addition to "visual inspection," which judges based on information obtained through "sight," there is "sensory inspection," which uses the five senses of humans, including "hearing," "touch," "smell," and "taste." In particular, the sense of touch, especially the feeling in the fingertips, is an important source of information second only to vision when inspecting the appearance and shape of products and parts. *For more detailed information, please refer to the related links. Feel free to contact us for more details.

"Visual inspection" occupies an important position in the quality control process of industrial products. In this inspection, defects and flaws that can be identified from the product's appearance are thoroughly checked and appropriately eliminated, preventing defective products from flowing to clients and the market, and playing a significant role in enhancing the company's trust and product quality. Additionally, it is possible to identify the causes during the manufacturing process from the results of defective product extraction, which can contribute to improvements in the manufacturing process, making the information obtained from visual inspections very useful. *For more detailed information, please refer to the related links. Feel free to contact us for further inquiries.*

A printed circuit board (PCB) refers to a general term for "printed wiring boards," which are formed with conductive metal in a circuit pattern on an insulating board, and "printed circuit boards," where electronic components such as IC devices containing semiconductors and resistors are mounted through soldering. Visual inspection, used as a shipping inspection for printed circuit boards, is conducted after the manufacturing of printed wiring boards and after the mounting of electronic components on printed circuit boards. The types of defects that occur during PCB manufacturing are diverse, and it is necessary to visually inspect the complex and intricate shapes of the mounting surfaces from multiple angles. Therefore, visual inspection to confirm defects and faults in printed circuit boards by human eyes remains an indispensable inspection method, even in the current era of increasing mechanization. *For more detailed information, please refer to the related links.

In times of disaster, not only emergency food but also long-term storage of drinking water is necessary. Naturally, river water cannot be consumed. While I don't think anyone would consider drinking from the Dotonbori River, even seemingly clean mountain streams contain many bacteria, including Campylobacter. River water contains not only bacteria but also many impurities, so while it can be made drinkable through filtration and boiling, unless you are someone who is seriously into camping, you probably wouldn't know the proper methods for heating or filtering. It is safer to avoid actions that could risk your health during a disaster. *For more details on the column, please refer to the related links.

The main components that make up a measuring device are the transmitter (sensing part) and the receiver, but the cables that connect them are also an important factor. If the condition of the cables is poor, it can lead to significant issues with the accuracy of the measurements. Moreover, a broken cable can pose a major risk, leading to the failure of important equipment, line stoppages, and in the worst-case scenario, accidents such as fires. Cables are often neglected in terms of management compared to equipment, but it is recommended to inspect cables along with the devices. In fact, based on past experiences, many issues such as abnormal readings or display failures have often been caused by cables. There are patterns in the locations where cable failures occur, and I will introduce some of them. *For detailed content of the column, you can view it through the related link.

The 4-20mA output is a type of analog output that outputs a current range from 4mA to 20mA, representing 0 to 100%. It is widely used as a standard analog output in measurement instruments due to the numerous advantages listed below: - It outputs 4mA even when the measurement value is 0, and it becomes 0mA in case of a disconnection, making abnormalities easy to identify. - There is no attenuation over long distances of several hundred meters (in the case of voltage output, the longer the distance, the more it attenuates due to resistance). - It is more resistant to noise compared to voltage signals. - Conversion to 1-5V is easy. For these reasons, it is adopted in many devices. *For detailed content of the column, you can view it through the related links.

Japan is blessed with water resources, but it also has a humid and warm environment that is conducive to the growth of bacteria and fungi. However, compared to other countries, the hygiene environment and quality control are very well established, so food is generally safe. However, this safety assurance is only valid if the food has been stored properly. If a disaster causes a power outage, the food in the refrigerator can spoil quickly. Perishable foods are assigned a "consumption deadline," which indicates the safe period for consumption, while other foods have a "best before date," which guarantees a period with minimal flavor deterioration. Generally, items referred to as "emergency food" can be stored for long periods, as they have thoroughly removed moisture and oxygen, which cause spoilage, from the manufacturing stage, allowing for storage of about five years. *For more detailed information, please refer to the related links.

To prevent electric shock accidents and fires, electrical products need to be tested for insulation resistance. This is particularly important for products intended for general households, as they are often handled and installed by individuals without electrical knowledge. The insulation resistance test involves applying a voltage that is typically 10 to 20 times higher than normal to the areas that should be insulated for a specified duration, and checking whether the insulating material causes insulation breakdown. Insulation breakdown is a phenomenon that occurs when the strength of the electric field applied to the insulator exceeds a certain value, causing a rapid decrease in electrical resistance and allowing electricity to pass through. *For more detailed information, please refer to the related links.

In recent years, there have been many significant earthquakes, starting with the Noto Peninsula earthquake. Not only that, but there are also concerns about the occurrence of earthquakes such as the Tokyo metropolitan area earthquake and the Nankai Trough earthquake, and the probability of their occurrence is increasing day by day. As long as we live on the Japanese archipelago, earthquakes are an unavoidable disaster. What we can do is simply to "prepare." Earthquakes are phenomena caused by global-scale activities, and they possess a power that we, as living beings, cannot possibly contend with. Unfortunately, the saying "preparedness prevents worry" does not fully apply, but at the very least, there is a significant difference in survival probability between those who take disaster preparedness measures and those who do not. So, what should we prepare for? Humans are creatures with a highly developed brain, which comes at the cost of being very inefficient in terms of energy consumption, so when sleep and food are cut off, we become unable to function at an early stage. Additionally, we are vulnerable to infectious diseases and have low natural healing abilities, so we can become ill in unsanitary environments. *For more details on the column, please refer to the related links.

This time, we will introduce the inspection of measurement device components using a constant temperature chamber. The inspection conducted this time was on a "temperature sensor" that measures temperature. A commonly used method for checking the integrity and functionality of sensors is to create a pseudo-measurement environment and actually operate the sensor within it. In the case of a temperature sensor, if it shows the same temperature of 25°C in that environment, we can determine that the product is good. However, maintaining a constant temperature in a room with air convection is very challenging. The fact that manufacturers promote their air conditioners with points like "we evenly heat (or cool) your room" can be seen as a reflection of the difficulty in maintaining a constant temperature indoors. *For more detailed information, you can view it through the related links.

Electronic components and circuit boards used in precision machinery undergo various inspections before manufacturing and assembly, with only the good products being incorporated into the final product. However, during the long inventory period from manufacturing to shipping, or in cases where manufacturing plants are overseas and transportation takes time, the risks of defects caused by "aging changes" or "vibration and shock" cannot be completely eliminated. In fact, manufacturers have indicated that if there are abnormalities in the internal settings of the product, there may also be some abnormalities in the circuit board itself. Therefore, pre-shipment inspections are very effective in preventing the risk of products with potential defects in the circuit boards from entering the market. Our company supports your business with high-quality and meticulous product inspections, leveraging the extensive experience and know-how gained from many years of calibration, repair, inspection, and testing of electronic devices, measuring instruments, and precision machinery.

PSE (Product Safety Electrical Equipment) is a regulation aimed at ensuring the safety of electrical equipment and electrical components used in Japan. The PSE mark certifies that these electrical products comply with safety standards based on Japan's Electrical Appliance and Material Safety Law (DENAN Law). This mark guarantees that electrical products are properly designed, manufactured, and can be used safely. Even for electrical equipment and components manufactured overseas, obtaining the PSE mark is necessary for domestic sales. Self-inspection refers to the process of verifying whether the product maintains the safety standards established when it obtained PSE certification for each production run. This must clear items such as "product functionality verification," "safety verification," and "record keeping." Our company, which specializes in inspection services, assists in confirming whether the product maintains the safety standards established when it obtained PSE certification through a process called "pre-shipment inspection." *For more detailed information, please refer to the related links.

When it comes to the use of disaster prevention supplies, people tend to focus on "natural disasters such as typhoons and earthquakes," but it is not limited to just that. Situations like power outages and water shortages can also occur due to damage or failure of infrastructure. This time, I will discuss the infrastructure that supports our lives and the risks associated with its aging. Infrastructure such as roads, bridges, water supply and sewage systems, and power grids deteriorates over time and requires proper maintenance.

Measuring instruments, which play an important role in various fields, are used in manufacturing and industrial production to ensure product quality through accurate data collection of chemical components and environmental conditions, as well as analysis and judgment based on that data. While measuring instruments are often installed in the same environment or location to detect data trends and slight changes, there are also benefits to taking them outside for operation. For example, by bringing measuring instruments to the field, it is possible to collect real-time data based on the environment and conditions, leading to the acquisition of realistic data that cannot be obtained in laboratories or research facilities. Furthermore, the ability to measure in different locations and conditions increases the number of cases that can be addressed, thereby expanding the application range of measuring instruments. Additionally, bringing measuring instruments to the field allows for rapid response when issues such as abnormalities are detected, enabling the identification of causes on-site and immediate implementation of countermeasures. *For detailed content of the article, please refer to the related links.
