We will introduce a solution to the problem of the dew point not decreasing. A portable dew point meter was used to measure high-purity nitrogen. A regulator was installed on the cylinder, and a sampling tube was connected to the dew point meter to measure the dew point. After running for about 2 hours, the dew point only decreased to around -60°C, and measuring other cylinders did not change the situation. The cause was insufficient purging of the sample piping system. It is necessary to either increase the flow rate or extend the purging time. Additionally, there was an influence from the surrounding components on the primary side of the dew point meter. Please use piping made of materials that do not allow moisture to permeate, or are difficult to permeate, such as metal piping or PTFE. [Issues/Phenomena] - When the chamber was left open, the dew point rose to around -40°C, gradually moving towards negative but not responding quickly. - After running for about 2 hours, the dew point only decreased to around -60°C. - The cylinder was empty, and measuring another cylinder immediately did not change the situation. *For more details, please refer to the external link page or feel free to contact us.

We will introduce the case of measuring the dew point of the atmosphere inside heat treatment furnaces and electric furnaces, or the exhaust gas, using a "dew point meter" that measures the moisture contained in gas and air. In industrial furnaces, industrial gas is supplied to create a special atmosphere inside the furnace. The products manufactured in that furnace may be significantly affected in quality if there are differences in the composition and moisture content of the internal atmosphere, so the internal atmosphere is continuously monitored. In cases where the internal atmosphere exceeds 200°C, components that provide a cooling effect can be attached to the sample piping, allowing for adjustments to create suitable conditions for measurement. Additionally, there are instances where the moisture content in the exhaust gas after the combustion process is related to the quality of the manufactured products. In such cases, the dew point temperature of the exhaust gas is continuously monitored at fixed points or measured at arbitrary spot points. [Case Details] ■ Introduced Product: Dew Point Meter ■ Purpose of Introduction: Measurement of the dew point of the atmosphere inside heat treatment furnaces and electric furnaces, or exhaust gas. *For more details, please refer to the external link page or feel free to contact us.

We will introduce a case where a "dew point meter" was implemented to measure the moisture content in gas and air, specifically for measuring the dew point of natural gas and the atmosphere inside natural gas tanks. Natural gas supplied in cold regions may freeze inside the piping due to low external temperatures, depending on the moisture content. To prevent freezing, measures are taken to reduce the moisture content as much as possible through moisture adsorption and removal during the natural gas refining process, and sensors are installed in the supply piping to continuously monitor the moisture content. Additionally, gas tanks used for storing and transporting natural gas are purged with N2 to prevent the risk of ignition and explosion from vaporized gas. The dew point temperature inside is measured, and the changes in this value are monitored to confirm the purging status.

We will introduce a case where a "dew point meter" was implemented to measure the moisture content in gases and air, specifically for dew point measurement in semiconductor manufacturing equipment (glove boxes). The gases used in the semiconductor manufacturing process often require high purity, and the moisture content in the gas significantly affects the quality of the manufactured products. To measure the dew point temperature of gases supplied to sealed areas such as product manufacturing equipment and the internal atmosphere of sealed environments, sensors are installed for continuous monitoring. Additionally, the dew point measurement is also used in devices such as glove boxes, which are widely used in other manufacturing products, to monitor the atmosphere inside the device and the gases supplied to it. 【Case Details】 ■ Product Introduced: Dew Point Meter ■ Purpose of Introduction: Dew Point Measurement for Semiconductor Manufacturing Equipment (Glove Box) *For more details, please refer to the external link page or feel free to contact us.

We will introduce a case where a "dew point meter" was implemented to measure the moisture content in gas and air, and the dew point measurement of dry air (inside a dry room) was conducted. The factory supplies dry air to various locations for different applications. Dry air requires a certain level of dryness, and many examples establish standards based on the moisture content, using dew point meters as a factor to determine whether the conditions meet the standards. In addition to installing sensors on the air dryer, the supply source, to continuously monitor the dew point temperature, there is also a method of extracting air from arbitrary points in the piping that supplies the factory to conduct spot measurements. Furthermore, in dry rooms where dry air is filled indoors, sensors are installed within the room to continuously monitor the dew point temperature of the indoor atmosphere.

We will introduce a case where a "dew point meter" was implemented to measure the moisture contained in gases and air, and to manage the dew point temperature of industrial gas manufacturing lines (such as air separation units). Dew point meter sensors were installed around the piping and storage tanks that transport industrial gases produced in the industrial gas plant, continuously measuring the dew point temperature of the industrial gases supplied from the manufacturing line that operates 24 hours a day. Quality standards are established for the dew point temperature managed in the industrial gas manufacturing line, and constant monitoring is conducted to ensure compliance with these standards, along with recording measurement values and triggering alarms in case of emergencies.

We will introduce a case where we implemented a "dew point meter" to measure the moisture contained in gases such as gas and air, and conducted dew point measurements of gases in cylinders (N2, O2, Ar, H2, He, SF6, etc.). We measure the dew point temperature of gases filled in general industrial gas cylinders. For example, if the moisture content in Ar gas used for argon welding is high, the risk of oxidation on the welding surface increases, so it must be below a certain moisture level. In environments where industrial gases are used, if moisture contamination occurs, it can adversely affect product quality. Therefore, we measure the dew point temperature of the gas in the cylinder to confirm the gas quality.
