Features

The refrigeration system includes a compressor from a well-known overseas brand with high-quality core components.
The hot gas bypass technology is used to ensure economic and long-term stable running of the test chamber.
The built-in lighting system is well matched with large multi-layer thermal insulation high-transmission observation window, which contributes to excellent visibility in the test space.
Patented external pressure humidification system well matched with imported high-quality steam solenoid valve ensures high humidification efficiency and a wide range of damp heat curve.
Linear conversion of various temperature and humidity algorithms brings excellent equipment performance.
The stainless steel liner with mirror finish is high-end, stylish and rust resistant.
The environmental test chamber can control both temperature and humidity within a wide range.
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).

Notes:

The range of temperature and humidity above is the results tested at an ambient temperature of 20℃ (room temperature) or cooling system water temperature of 25℃ and with no load.
Measurement was made as per the test method of IEC 60068-3-6: 2001/GB/T 2424.6-2006/JMT K09: 2009 based on the effective space formed with a distance of 1/10 to each edge in the internal box.
