High And Low Temperature Test Chamber

A.Introduction

The high and low temperature test chamber, also known as the environmental test chamber, tests the heat resistance, cold resistance, and dry resistance of various materials. Suitable for electronics, electrical appliances, food, vehicles, metals, chemicals, building materials and other factories.

B.Control Mode

      The Balanced Temperature Control System (BTHC) uses P.I.D. to control the SSR so that the heating amount of the system is equal to the loss, so it can be used stably for a long time.
