DESCRIPTION
It 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. It is suitable for testing the quality of products such as electronics, electrical appliances, communications, instruments, vehicles, plastic products, metals, food, chemicals, building materials, medical treatment, and aerospace.
Feature
1. The three-in-one design is easy to use and does not take up space.
2. Each test area can individually test three different control conditions of high temperature, low temperature or constant temperature and humidity.
3. All systems are individually independent: three sets of refrigeration systems, three sets of heating and humidification systems, and three sets of control systems are adopted, so the control is stable and accurate, and the service life of the parts can be prolonged.
4. Touch setting mode, completely controlled and locked by microcomputer, and has PID value automatic calculation function
