Product Description

AHTT2820 precision dew point hygrometer based on the principle of optical chilled mirror, it is a temperature and humidity measurement instrument. This principle is distinguished from indirect measurement of humidity through changes in capacitance and resistance, it directly measures according to the definition of humidity/dew point. 
Condensation mirror of AHTT2820 precision dew point hygrometer is processed by a special semiconductor, makes it have corrosion resistance for certain degree, also have high and low temperature resistance. It uses precision platinum resistance to measure dew point and temperature. It can adapt to most applications and ensure measurement accuracy. And can even be used in harsh environment. It adopts a 4-inch colorful capacitive touch screen display, which is simple, convenient to operate. Curve and multiple parameter conversion can meet various requirements.

Application

• In measurement and testing industry, Chilled mirror dew point hygrometer has high measurement accuracy and wide measurement range. Then it is often used to calibrate and test various temperature and humidity sensor equipment with humidity-sensitive resistor or capacitor. 
  In the production of food and medicine, process like high-temperature and high-humidity disinfection, removal of excess water are required. In such environment, humidity-sensitive resistors and humidity-sensitive capacitors are easy to drift and invalid in short time. However the chilled mirror dew point hygrometer can work in such environment. Compared with humidity sensitive resistors and humidity sensitive capacitors, it has advantages like long-term stability, no drift, and can work long time in harsh environment. 
  In laboratory environments such as university scientific research, high measurement accuracy is a must. But there are a variety of chemical substances, most of them have adverse effects on sensors. Normal humidity-sensitive material sensors are prone to drift or even invalid due to corrosion damage in various chemical environments. Chilled mirror dew point hygrometer can resist corrosion in certain degree. As a scientific research assistant, they can provide reliable measurement data. 
  In electronic power industry, high-voltage insulation is very critical. Sulfur hexafluoride (SF6) is an insulating gas commonly used in the high-voltage power industry. Excessive water content of SF6 can easily decompose SF6 into toxic and corrosive components, and cause SF6 insulation not meet the requirements, then cause fire and damage to the power equipment. Therefore, it is particularly important to monitor the water vapor content. The chilled mirror dew point hygrometer can resist corrosion resistance in certain degree and can meet the requirements. 
  In various fields such as meteorological environment, factors such as ultraviolet rays, high temperature, low temperature, high humidity, unconventional chemical substances and pressure may restrict ordinary humidity-sensitive material sensors. While chilled mirror dew point hygrometer can still guarantee the data stability and accuracy even in harsh environment.
