High-Low Temp. Test Chamber
Quantity : 100 Price : USD2000-5000
Performance characteristics of low temperature test chamber：
1. In the refrigeration system, the condensation adopts air cooling mode, which has a wide temperature control range, which can meet the user's various needs.
2. With a unique balanced temperature control method, with stable and balanced heating capacity, high precision and high stable temperature control can be carried out;The temperature is displayed by touch screen, easy to read, precise and convenient.
3. Adjust the temperature error value to meet more accurate test conditions.With the setting of temperature, it is easy to operate the refrigeration circuit.
4. The box door is equipped with a large observation window, which can observe the test status of the test sample at any time.
5. with functions of high temperature on, can open the refrigerator when the temperature in the oven to 150 ℃, facilitate continuous round-trip experiment was carried out between the high temperature and low temperature.
6. Self-diagnosis function, overload protection of refrigerator, high pressure switch, overload relay, thermal protection device, etc., to ensure the safety of use.
7. Use the multi-wing fan to supply the wind with strong air circulation and avoid any dead Angle, so that the temperature can be evenly distributed in the test area.
8. Wind circulation is designed with wind return wind. The wind pressure and wind speed are in accordance with the test standard.
9. Temperature rise, cooling and system complete independence can improve efficiency, reduce test cost, increase life span and reduce failure rate.
