Technical Characteristics

Highly reliable and stable imported piston compressor.
Condensate water temperature and water pressure sensor; pre-warning and warning functions against abnormal water circuit.
Multi-point temperature control function; multiple optional test piece sensors to control temperature at air outlet, center point, max., min. or average temperature control of test pieces.
Imported high-precision capacitive humidity sensor with Grade A precision PT100 to realize higher temperature and humidity measurement accuracy.
The test chamber can judge the program jump time automatically, store energy in advance, and enable refrigeration immediately in cooling section on the premise of ensuring energy conservation without waiting for pressure reduction and energy storage of the refrigeration system.
A wide range of temperature and humidity control; relative humidity: 15%~95%RH (no heat source in working space during damp heat test). Temperature range: 10℃~95℃ (low temperature auxiliary system can be added to satisfy the requirements for low temperature).
Able to switch among various algorithms automatically such as energy pre-input, overshoot suppression, automatic rate matching of linear temperature rise and drop, etc., to ensure the equipment’s excellent linear following function, and compliance with the fluctuation range (<0.5℃) and temperature overshoot (<2℃).
