![]() The Raoul effect is caused by water-soluble substances. One is the Raoul effect, and the other is changing the level of specular background radiation. Its impact is mainly manifested in two aspects. ![]() Mirror contamination is a prominent problem in dew point meter. Influence of mirror pollution to dew point meter Here are 3 key point for measuring dew point: During use, the pipe that sucks in the sample air must be kept clean, otherwise the impurities in the pipe will absorb or release moisture, causing measurement errors. Its humidity measurement accuracy is high, but it needs a very smooth mirror surface, a highly accurate temperature control system, and a highly sensitive optical detection system for dew drops (ice crystals). ![]() The principle of the dew point meter is to cool a mirror in the sample's wet air until the moment when dew drops (or ice crystals) appear on the mirror, and then measure the average temperature of the mirror, which is the dew point (frost) temperature. Its application is becoming more and more extensive, and maintenance and repair are becoming increasingly important. Dew point meter is an instrument that can directly measure the dew point temperature. In addition, the international measurement of the micro water or gas dew point in the gas, especially the expression of the water content in gas, is gradually unified to the dew temperature. It is one of the ways to express the absolute humidity of the gas. The dew point can be simply understood as the temperature at which the water vapor content in the gas reaches the saturated state. This plays a very important role in the safe operation of the device and laboratory. It is often necessary to quickly and accurately measure the amount of micro water in samples (such as ethylene, propylene and other production materials) in certain situations (such as on-site or laboratory). This software is the most advanced temperature and humidity monitoring software package for Dewpoint Meters available today.Many industries, such as petrochemical, electrical power, electronics, aerospace, metallurgy, textile and so on, have higher and higher requirements for humidity measurement. To analyze the data the DewCheck 4 comes with the special Ideal Finish Analysis software. All parameters can be stored in the dewmeter's memory, tagged with a date and time.įor communication between DewCheck 4 dewmeter and a PC the DewCheck dewmeter USB cable is standard supplied. The difference between the surface temperature and dewpoint temperature indicates the optimal climate conditions for painting. This easy to use and robust dewmeter conforms to ISO 8502-4 & ASTM D3276-07 and measures the relative humidity (%RH), ambient temperature (Ta) and surface temperature (Ts) and calculates the dewpoint temperature (Td) and the difference between the dewpoint temperature and the surface temperature (ÄT). The TQC DewCheck 4 - Dewpoint Meter (DPM)/ Dewmeter is an extremely versatile dewpoint meter to measure and record all climate parameters required to treat surfaces.
