Example of calibration: Calibration of an oxygen meter

Inspection before purging, purging, zero point calibration, span calibration, re-purge confirmation, and explanation until completion!

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.*

The dangers of volcanic gases (sulfurous gas and sulfur dioxide) to the human body.

The mechanism by which sulfurous gas and sulfur dioxide gas (SO2 gas) affect the human body.

Volcanic accidents remind us of the disaster caused by the eruption of Mount Ontake in 2014. However, in terms of the number of volcanic incidents, accidents due to volcanic gas poisoning are overwhelmingly more frequent and are reported every year. Additionally, with the revision of the Active Volcano Law, local governments are obligated to ensure the safety of tourists, increasing the importance of monitoring volcanic gases. This time, I will explain the mechanisms by which volcanic gases (sulfur dioxide and sulfurous gas) affect the human body. <Sulfurous Gas and Sulfur Dioxide (SO2)> Harmful gases such as sulfurous gas and sulfur dioxide (SO2) damage the epithelial lining of the airways. This damage leads to the accumulation of inflammatory cells in the airways, causing inflammation. Due to this inflammation, the airways become sensitive, leading to airway constriction and triggering asthma attacks. The type of inflammation varies among individuals, resulting in allergic asthma or COPD. It is believed that various factors, including genetic and environmental influences, contribute to these types. Therefore, individuals have different tolerances to the gas, and there have been reports of asthma patients experiencing attacks even at low concentrations of around 0.2 ppm. Additionally, it is said that there are many undiagnosed asthma patients who are unaware of their condition.

【Disaster Prevention and Crisis Management】The Dangers of Volcanic Gases to Human Health

The mechanism of the impact of volcanic gases (SO2) on the human body and the importance of early detection.

In the field of disaster prevention and crisis management, responses to unexpected natural disasters are required. In particular, accidents caused by volcanic gases not only evoke memories of the Ontake Mountain eruption disaster but are also reported every year, making their risks significant. With the revision of the active volcano law, local governments are mandated to ensure the safety of tourists, increasing the importance of monitoring volcanic gases. Our product helps understand the mechanisms by which volcanic gases (sulfur dioxide and sulfurous gas) affect the human body and supports rapid responses. Sulfur dioxide and sulfurous gas can damage airway epithelium and trigger inflammation, potentially leading to asthma attacks. Since individual tolerance to gases varies and effects can occur even at low concentrations, early detection and information sharing are essential. 【Usage Scenarios】 - Monitoring areas around volcanoes - Understanding gas concentrations during evacuation guidance - Safety management for tourists 【Benefits of Implementation】 - Early detection of rising gas concentrations, contributing to swift evacuation guidance - Supporting accurate situational judgment through gas information sharing among stakeholders - Reducing the risk of volcanic gas poisoning accidents

Instran Online Chlorine Meter

Continuous measurement of total chlorine concentration in water using an ion-selective electrode method!

Advantages This method is a very simple chlorine measurement technique. It consumes a small amount of reagents, and chromate ions, which interfere in amperometric methods, do not cause interference here. Conductivity and calcium, which are significant interferences in the DPD method, do not interfere either. Measurement Principle – ISE Electrode Analysis is performed using the Standard Known Addition (SKA) method. Two measurements are taken, and the concentration is calculated from the difference between the two and the slope during the calibration curve creation. The reference for calculating the results is not an absolute value but the relative difference in mV, so any changes that may occur in the matrix sample are corrected by both of these lectures. This allows for the avoidance of external interference. Measurement Method It is based on the measurement of iodide. Through the reaction of chlorine, buffer solution, and potassium iodide reagent, chlorine reacts with potassium, releasing iodide. Chlorine displaces iodide. Subsequently, the ISE electrode measures the iodide, and the amount of iodide measured corresponds to the chlorine in the sample.

Instran Online Nitrate Concentration Meter

Continuous measurement of nitrate concentration in water is possible!

Method - Ion Selective Electrode Reagent 1 is added before analysis to activate the electrode. After that, the first measurement is taken. Next, a small amount of a high-concentration nitrate solution is added, and a second mV measurement is performed to calculate the results. If an extraction solution is used, cleaning with an ammonia-based cleaning solution is necessary after analysis to prevent cross-contamination. Many probes are affected by interference from nitrite and chloride, but in this method, using the extraction solution at the beginning of the analysis completely removes the influence of these two ions. Therefore, the only ion affecting the measurement is the nitrate ion (NO₃⁻).

Instran Online Calcium Hardness Meter

High-precision measurements are possible while eliminating the influence of magnesium!

After adding the reagents to prepare the sample under specified conditions, the injection of the titrant is performed. The minimum injection volume (0.015 ml) achieved by the module's syringe driver ensures very high precision, with a maximum difference of only three drops even in two consecutive measurements using the same standard sample. Additionally, improvements in the software have accelerated the injection of the titrant in the initial stages, while slowing down the injection rate as it approaches the endpoint, ensuring even higher accuracy. This method is a modification of the method developed by Reilly (published in Analytical Chemistry). By adjusting the pH of the solution, magnesium precipitates and is not included in the titration target. It is specialized for calcium even in the presence of large amounts of magnesium. The measurement wavelength is adjusted to the calcium–calcon (Ca–Calcon) complex, while the reference wavelength is set to the EDTA–calcon complex, allowing for accurate and reproducible detection of the endpoint.

Instran Online Nitrite Concentration Meter

Even at a concentration of 100 ppb, which is often considered the legal limit in drinking water, a significantly high absorbance can be obtained.

After adding the sample to the measurement cell, several reagents are added to adjust the solution conditions (such as pH and the atomic valence of elements). Subsequently, a blank measurement is performed to correct for the effects of temperature and turbidity. Then, the final reagent is added, which reacts with the solution to produce color and is measured at the appropriate wavelength. Thanks to the photometer used, results can be obtained with very high accuracy. This method is based on the reaction in which nitrous acid generated from nitrite ions undergoes a diazotization reaction with sulfanilamide, forming a vivid colored diazo dye.

Instran Online Copper Ion Concentration Meter

Continuous measurement of copper ion concentration in water is possible!

Method - Colorimetric Analysis After adding the sample to the measurement cell, several reagents are added to adjust the conditions of the solution (such as pH and oxidation state). Subsequently, a blank measurement is performed to correct for the effects of temperature and turbidity. Then, the final reagent is added, which reacts with the solution to produce a color that is measured at the appropriate wavelength. The photometer used allows for highly accurate measurement results. This method is based on the reduction of copper(II) to copper(I) in acidic solutions. The neocuproine reagent specifically reacts with cuprous ions (Cu⁺). If present, iron can also be reduced to iron(II) (Fe²⁺) and may react with neocuproine. This method is specific to copper, and the cuprous-neocuproine complex has a clear and relatively strong absorbance, allowing for the measurement of low concentrations of copper at the ppb level. The influence of iron can be removed with additional reagents.
