This machine is designed for determining changes in physical property of leather, plastics, rubber, and fabric after or before heating and ozone aging. The aging property is determined by measuring changes in physical property of a specimen. This machine uses the touch screen as a operation interface, simple and smart.

The P.I.D.tuning method and SSR control method are used for controlling temperature. The explosion –proof glass and the built-in lighting lamp are convenient for observing changes in specimen during testing air outlet on the top of the chamber discharges harmful gas out of the chamber. The circulating system in the chamber can reduce temperature deviation. The specimen turntable makes the specimen to be heated equally and fully. The over-temperature protector will be trigged when the temperature limit has been reached. The alarm message will appear on the touch screen.
