Laboratory Equipments Temperature And Humidity Chamber Universal Programmable
Usage :
The environmental test chamber in China is applied to test the capabilities of heat-resistance, cold-resistance, dry-resistance and moisture-resistance of materials. It is mainly used in testing the adaptability of electronics, electrical appliances, food, automobile, rubber and plastic, metal and other products, parts and materials in the high and low temperature and humid environment when storage, transport and using.
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.
