Quotation for Two Box Cold and Hot Shock Test Boxes

Two box thermal shock test chamber

Two box thermal shock test chamberAlso known as environmental testing machine, it tests the heat resistance, cold resistance, dry resistance, and moisture resistance of various materials. Suitable for use in factories such as electronics, electronics, food, vehicles, metals, chemicals, and building materials.

Control methods and features:

It utilizes low-temperature and high-temperature thermal storage tanks to quickly move the basket into the cold and hot tanks according to operational needs, thereby achieving a rapid temperature shock effect. The balanced temperature control system (BTC) is a specially designed air supply circulation system that controls the SSR in a P.I.D. manner, ensuring that the heating amount of the system is equal to the heat loss, thus enabling long-term stable use
