What is a dew point meter? What is a dew point? We will introduce the types of dew point meters and their measurement principles.
■What is a Dew Point Meter? A dew point meter is a device used to measure the very small amount of moisture contained in gases such as air or dry air. It is expressed in terms of the temperature at which moisture in the gas condenses, known as the dew point temperature (°C dp). ■What is Dew Point? The temperature at which condensation, or the process of liquefaction, occurs when cooling a gas. This ultimately represents the temperature at which air is in equilibrium with water and is saturated. The dew point is an important factor not only in everyday life but also in various industrial fields (such as painting, semiconductors, batteries, power, railways, pharmaceuticals, gas refining, renewable energy, chemical plants, agriculture, food, air, industrial gases, steel, air conditioning, heat treatment, etc.). ■Types of Dew Point Meters There are several types of dew point meters based on their measurement principles. The main types currently in use are as follows: 1) Capacitive Dew Point Meter (Aluminum Oxide) 2) Capacitive Dew Point Meter (Polymer) 3) Mirror-Cooling Dew Point Meter 4) Phosphorus Pentoxide Dew Point Meter 5) Laser Dew Point Meter
Introduction to dew point meters, oxygen concentration meters, temperature and humidity meters, and anemometers for semiconductor manufacturing and clean rooms.
In the semiconductor manufacturing process, the removal of moisture and oxygen is a significant challenge. Our dew point meters, temperature and humidity meters, and oxygen concentration meters are used in various processes such as semiconductor manufacturing, transportation, and inspection. They are also used for measuring the dehumidification in dry air and the gas purity of nitrogen gas, argon gas, helium gas, and hydrogen gas. For moisture measurement, we primarily use the TK-100 capacitive dew point meter (alumina type), which can measure down to a minimum dew point of -100°C, the TE-660 dew point meter (polymer type) for a minimum dew point of -60°C, and the MBW mirror-cooled (mirror type) dew point meter, which can measure from -95°C to +99°C and is used when high precision is required or as a reference instrument for dew point meters. In the humidity domain, the simple EE060 and the EE33 temperature and humidity meter, which is equipped with measures to prevent condensation in high temperature and high humidity environments, are mainly used. For oxygen concentration measurement, during oxygen removal by hydrogen substitution, the 2001LC galvanic cell oxygen concentration meter is used for PPM levels, while in situations without hydrogen, the Model 4100 zirconia oxygen concentration meter is used for analysis down to PPB levels, among various scenarios. Additionally, an anemometer is also utilized for measuring micro-wind in clean rooms and manufacturing equipment.

Do you know about dew point meters? June 10th has been registered as "Dew Point Meter Day" by the Japan Anniversary Association!
Techne Measurement Co., Ltd. has applied to the Japan Anniversary Association to designate June 10 as Dew Point Meter Day, and it has been officially recognized. We hope that this anniversary will serve as an opportunity to convey the benefits of dew point measurement and encourage more people to consider and feel closer to the concept of dew point measurement. We have provided materials and videos explaining dew point meters and Dew Point Meter Day. Please take a look. **Purpose of Registration** A "dew point meter" is a device that measures the moisture content in gases. In the industrial sector, dew point measurement contributes to improving manufacturing efficiency and promotes environmentally friendly production. It also helps enhance product quality. The goal is to spread awareness of the various benefits of dew point measurement, as well as basic knowledge about dew point meters, their correct usage, and the importance of calibration. **Origin of the Date** The date is derived from a wordplay where "6" and "10" can be read as "ro (6) ten (10)."

Method for calculating the dew point value
The calculation methods are described on the linked website below: 1) Dew point Td℃, frost point Tf℃ 2) Saturated water vapor pressure e(Pa) 3) Relative humidity Uw(%) 4) Absolute humidity dv(kg/m3, g/m3) 5) Mole fraction xv(mol/mol) 6) Weight fraction wv(kg/kg, g/g, etc.)
Explaining the differences from the basics: Humidity!
○ What is the dew point? The dew point (dew point temperature) is the temperature at which condensation begins when a gas is cooled. If the amount of water vapor in the air is low, the dew point is low; if there is a lot of water vapor, the dew point is high. In other words, the dew point quantifies the amount of water vapor in the air and represents something similar to humidity. ○ What is saturated water vapor? The state in which "no more moisture can enter the air" is called the "saturated state," and the amount of water vapor in the state where "no more water vapor can enter the air" is referred to as "saturated water vapor." *For more details, please check the URL below.
Relative humidity/saturation vapor pressure of water
○ What is humidity? It is a numerical value that represents the amount of water vapor contained in the atmosphere as a ratio. Even at the same temperature, the perception differs with varying humidity levels. When humidity is high, it feels hotter. There are several indicators of humidity. This time, we will introduce the commonly used relative humidity. *For more details, please be sure to check the URL below.
