Environmental simulation chamber for testing materials by simulating conditions at desired temperature and humidity levels

These chambers provide an economical option for simulating a variety of temperature and humidity conditions. They are suitable for high- and low-temperature tests, constant climate exposure, and alternating cycles to check how materials and components respond to changing environments.

Power supply			380V (three phase four wire protective grounding wire)
Condensing method			Air-cooled/water-cooled (Models ending with “A” are configured as air-cooled,while those ending with “W” are water-cooled versions. For example,ER-02JA refers to an air-cooled chamber,and ER-02JW indicates a water-cooled chamber.)

For air-cooled models, performance specifications are based on an ambient temperature of 25 °C and relative humidity of ≤85% measured with the chamber empty. For water-cooled models, reference conditions are an ambient temperature between 15 °C and 35 °C, relative humidity of ≤85%, and cooling water temperature of ≤ 28℃, also measured without test samples inside the chamber.
