Product Description

Temperature and humidity chamber is one kind of environmental test equipment, applicable to temperature-humidity test of mini electrical, instrumentation, automotive, aerospace, electronic chemicals, materials components,  and aging test, the temperature and humidity chamber adopts the most reasonable structure and most stable control method that adds value to its good appearance, easiness to operate, safeness and high-precision temperature and humidity control.   It is ideal for temperature and humidity test with GB、GJB、ASTM standards met.

In testing procedure, the chamber achieves fully-automatic control of cooling, heating, dehumidification, humidification and adding water, which enable the chamber to operate in comprehensive environmental test with temperature-humidity involved, besides, it can also make individual testing environment of high temperature, low temperature, alternating temperature and humidity, and steady dame heat.
