Electrical Temperature Humidity Test Chamber / Controlled Environmental Chambers
Introduction:
Temperature humidity chambers (also known as climatic or climate test chambers) simulate the effects that a range of temperature and humidity conditions have on a product or material.Temperature and Humidity Test Chamber Maintenance principle: Since the chamber is composed of several systems including electric, cooling and mechanical system. Once any problem emerges, the whole equipment shall be checked and analyzed systematically. Generally, the “other reason first, equipment problem then” principle shall apply, which means firstly check if the problems are caused by external factors like the cooling system & power, then check the equipment step by step, for example, firstly check the electric system according to the electric wiring diagram, then check if there is any problem with the cooling system. It is not advisable to remove or replace any part before the reason is clear, or it might cause many troubles.
