• Product Name

Two box thermal shock test chamber

Divided into two parts: high temperature zone and low temperature zone, the test sample is placed in one of the working rooms and passed throughhas-beenRealize the switching of samples between high and low greenhouses through dynamic mode, and complete the cold and hot temperature shock test. The unique heat and cold storage structure ensures good constant temperature performance of the test chamber.

• Product Model

COK-50-2H

Note: The air-cooled type does not require the installation of a cooling tower, while the water-cooled type requires installation, depending on customer requirements.

• Sample limitations

This experimental equipment prohibits:

① Testing or storage of samples of flammable and volatile substances

② Testing or storage of corrosive substance samples

③ Testing or storage of biological samples

④ Testing or storage of strong electromagnetic emission source samples
