The aging test chamber is used as a thermal aging test for plastic materials (rubber, plastic), electrical insulation and other materials by scientific research units and chemical rubber plants. The results of aging tests depend on temperature adjustment, accuracy and temperature distribution inside the box. The condition, so the temperature of the aging test chamber is the most critical process parameter in the heat aging test process. The original aging test has been controlled by a bimetal temperature regulator. The bimetal temperature device is manually adjusted according to the reading displayed by the mercury thermometer, so the temperature control accuracy is not very high, and the contact point of the bimetal temperature device is often oxidized, which may cause control failure, in order to prolong the continuous operation cycle and service life of the aging test box. To improve the accuracy of the test, Yashilin Instrument has modified the temperature control system of the aging test chamber. YASELINE aging test chamber temperature control instrument adopts imported Korean ternary ST190 digital display high-precision integrated controller, which adopts thermal balance temperature regulation and humidity control mode, PID+SSR system co-channel coordinated control, and automatic calculus function, which can change temperature conditions. Correct immediately to make temperature control more precise and stable. It also has fault alarm and cause, processing prompt function; power-off protection function; calendar timing function; self-diagnosis and other functions.
