The RWDX-1 thermal stability tester is a new type of tester developed by our company according to the GB/T2951.32-2008 and 1EC60811-3-2:1985 standards. Its temperature control instrument adopts an intelligent instrument with PID self-tuning function, and on this basis, it is manually optimized to achieve optimal temperature regulation. Combined with a magnetic mixing device, the temperature of the working medium in a 1000m beaker can reach 2000.5C uniformly with minimal overshoot, In order to improve anti-interference ability and meet the requirements of continuous operation under laboratory conditions, high-quality power filters, fast response time and temperature sensors are used, and the thermal stability tester fully meets the requirements of the test standards
