Control Method and Features:

The Balanced Temperature and Humidity Control (BTHC) system uses a P.I.D. method to control the SSR, ensuring that the system's heating output equals the damp heat loss, thus enabling long-term stable operation.

The thermal aging test chamber is used in research institutions and factories for thermal aging tests on plastic materials (rubber, plastics), electrical insulation materials, and other materials. It conforms to national standards such as GB/T 3512-2014 and ISO 188:2011.

I. Performance:
