Constant Temperature Humidity Chamber

Name: Constant Temperature Humidity Chamber
Brand: Xi'an LIB Environmental Simulation Industry

The constant temperature humidity chamber simulates a stable, precise, and independently enclosed T&H environment through a temperature control (cooling, heating) system and a humidification system. The LIB constant temperature humidity chamber offers flexible, wide-ranging standard or customized temperature and humidity options (-70/-40/-20℃ ~ +150℃, 10%/20%RH ~ 98%RH), which can be used to test and determine the parameters and performance of electrical, electronic, and other products and materials after changes in temperature environments during high-temperature, low-temperature, alternating humidity and heat, or constant tests.

The LIB constant temperature humidity chamber offers various models such as benchtop, vertical, and walk-in types, and provides multiple customization options.

Optional Models : TH-100A, TH-225A, TH-800A, TH-1000A and more.

Applicable Testing Standards:UL 2580,SAE J2464,SAE J575，IEC 60086-4,UL 1642,IEC 61215,IEC 62717,VW 80000 and etc.
