Professional Temperature Humidity Test Chamber Stability -70℃
Usage :
This equipment can simulate different environment condition. It's appropriate for testing material performance, such as resist heat, LED,resist dry,resist humidity and resist cold. That can define performance of material.
Character:
1. Use the high precision microcomputer touch temperature and humidity controller with high stability of platinum resistance to temperature and wind speed in the circulatory system of temperature and humidity test.
2. control temperature&humidity well-distributed, precisely and steady.
3. Completely independent system separate for testing in high
temperature, low temperature and constant temperature&humidity
environment.
