Two Boxes Programmable Temperature Humidity Test Chamber
Product Introduction:
Temperature Environmental Testing Machine is designed for testing the capability of heat-endurance, cold-endurance, dryness-endurance, and humidity-endurance, suitable for quality control of the industries of electron, electrical equipment, vehicle, metal, foodstuffs, chemistry, building materials, luggage, adhesion tape, printing, packaging, etc.
1. The separation of humidifier circuit from electric circuit improves safety and protects the circuit against the leakage of water supply line.
2. Available in Chinese and English LCD touch screen, easy operation and program.
3. Able to display the relative date and information of the whole operating system in running mode, graphic display. Precautions, maintenance and troubleshooting appear on the screen instantly.
4. The Sirocco fan motor provides greater cyclic airflow to avoid dead corner in the chamber so as to obtain an uniform distribution of temperature and humidity.
5. The system of heating up, heating down, dehumidifying, and humidifying can be operated independently so as to reduce the cost of testing, extend the operating life of the machine and decrease the failure rate.
6. Water Supply adopts automatic watering System, Circulating water supply together with water filter.
Advantages:
1. High temperature and humidity uniformity, small temperature and humidity deviation (temperature uniformity <2 ºC, humidity uniformity <3% RH)
2. Good sealing performance, high-quality silicone seals, through layers of inspection, to ensure the tightness of the studio
3. The test noise is small, the noise generated by the test is less than 60 decibels, exceeding the category 2 standard, and close to the level 1 standard. Reduce the noise of the customer's environment and give you a more comfortable and quiet working environment.
4. The sample can be energized for testing, with the energized test function of the tested piece (load test)
