Temperature Humidity Test Chambers









Temperature range



Temperature Humidity Test Chambers is designed for testing the capability of heat-endurance,cold-endur.


Temperature humidity test chambers, also known as Climate chamber or Environmental Test Chamber.
Temperature humidity test chambers can simulate the different indicators of constant temperature and humidity climate quickly and accurately for testing products which need to check their performance of temperature testing (-40℃~+150℃), humidity testing (20~98%R.H.),both of temperature and humidity testing at the same time.chamber power can be customized.
Environmental Test Chamber which also call Constant Temperature Humidity Chamber is designed for detecting the material under a variety of environmental test equipment and performance of a variety of materials holding test, cooling-off test, heating-up test, moistening test and drying test… Suitable for electronic, electrical, communications, instrumentation, vehicles, plastic products, metals, food, chemicals, building materials, medical, aerospace and other products quality testing purposes,EN 14511.

Product Advantages

Haida series chambers meet international test performance standards. The units can be installed around the world for consistent testing at different facilities, supported by Haida Group and our cooperation prater in Australia, Dubai, India, Malaysia, Turkey and Vietnam. And our chambers feature two levels of overheat protection, and one levels of overcool protection. The system controller provides alarm messages with specific troubleshooting help to quickly resume testing.
The Haida series chambers have temperature change rates from 1 to 3°C per minute in average and controlled humidity from 10% to 95%. There are 6 sizes with interior volumes of 100 to 1000 Liters or we also provide tailor-made chambers of size. On the advance model for Cycling Chambers have temperature change rates from 3 to 15 °C, controlled humidity from 10 to 95%.
