The temperature measurement range is -40°C to +50°C.
Humidity measurement range is 20% to 95% RH.
This equipment provides a controlled temperature and humidity environment, which is used to test the accuracy of commercially available loop sensors for experimental environment monitoring and laser measurement correction.

The basic principle is to control n, R, and T to be fixed values according to PV=nRT, then multiply PV to a certain value. Put saturated water vapor <Ps> into the test area with larger or smaller volume, and the water vapor cannot maintain saturation <Pv>, and the predetermined humidity value can be obtained.
