Custom Reach-in Chamber

Overview

Glai Custom Reach-in Temperature and Humidity Test Chamber is used to test the performance of materials in various environments and test the heat resistance, cold resistance, dry resistance and humidity resistance of various materials. Suitable for testing the quality of products such as electronics, electrical appliances, mobile phones, communications, meters, vehicles, plastic products, metals, food, chemicals, building materials, medical care, aerospace, etc..

Test Chamber Applications

1. To simulate test environment with different temperature and humidity

2. Cyclic test includes climatic conditions: holding test, cooling-off test, heating-up test, moistening test and drying test…

3. Cable port with flexible silicone plug for cable routing to provide the condition of test unit under operation

4. Uncover test unit weakness in a short-term test with accelerated time effect

Fulfill the Standard:
The performance pointer meets the requirements of GB5170, 2, 3, 5, 6-95, "Basic parameter verification methods for environmental test equipment for electric and electronic products, low temperature, high temperature, constant humidity and heat, alternating humidity and heat test equipment"
Basic environmental test procedures for electric and electronic products Test A: Low temperature test method GB 2423.1-89 (IEC68-2-1)
Basic environmental test procedures for electric and electronic products Test B: High temperature test method GB 2423.2-89 (IEC68-2-2)
Basic environmental test procedures for electric and electronic products Test Ca: Constant humidity test method GB / T 2423.3-93 (IEC68-2-3)
Basic environmental test procedures for electric and electronic products Test Da: Alternating damp heat test method GB / T423.4-93 (IEC68-2-30)

Control methods and features:
The balanced temperature control system (BTHC) controls the SSR in the P.I.D. mode, so that the heating and humidification amount of the system is equal to the damp heat loss amount, so it can be used stably for a long time.
