In the previous article《What is the pressure dew point？How to measure？》China Atlas compressor Xiaobian gives you a simple introduction to what to measure the dew point？In this articleAtlas compressorXiaobian will give you a detailed introductionAir compressor dew point meterWhat are the categories of？

Classification of air compressor dew point meter, working principle

1, adsorption dew point meter

Adsorption dew-point instrument is a commonly used dew-point instrument. Its working principle is to use adsorbent to adsorb the water in the gas。When the adsorbent is saturated, the water in the gas is adsorbed to the adsorbent, thus reducing the water vapor content in the gas。The adsorption dew point instrument has the advantages of simple structure, convenient operation and accurate measurement, and is widely used in the humidity detection of air compressors and other industrial equipment。

2, cold atomic absorption method dew point instrument

The cold atomic absorption method dew point meter is a dew point instrument based on the principle of atomic absorption spectroscopy, which works by heating the gas to evaporate the water in it, and then measuring the water content in the gas by atomic absorption spectrometry。The cold atomic absorption dew point instrument has the advantages of wide measuring range, high sensitivity, stable accuracy, etc., and is suitable for the occasions with high dew point requirements。

Classification of air compressor dew point meter, measuring range

1, normal temperature dew point instrument

The normal temperature dew point instrument is a kind of dew point instrument specially used to measure the water vapor content in the air at normal temperature。Because the dew-point instrument is not sensitive to temperature change, it has high universality and reliability in practical application。However, the temperature dew point meter has a relatively narrow measuring range, generally between -40°C and +70°C。

2, low temperature dew point meter

Low temperature dew point instrument is a dew point instrument specially used to measure the water vapor content in the air under low temperature environment。The low temperature dew point instrument has strong cold resistance and can work normally at very low temperatures。However, low temperature dew point instruments are more expensive and require higher environmental conditions。

3, high temperature dew point meter

High temperature dew point instrument is a dew point instrument specially used to measure the water vapor content in the air under high temperature environment。The high temperature dew point instrument has strong heat resistance and can work normally in an environment of up to hundreds of degrees Celsius。However, high temperature dew point instruments are more expensive and require higher environmental conditions。
