According to the technical requirements of Shanghai Jiao Tong University, after careful design and testing, our company has finally developed a successful programmable alternating oil bath. It adopts touch screen technology and uses multi-channel heating and cooling technology, multi-threaded measurement and control, to control the alternating temperature of oil temperature in the range of 0-200 degrees through multiple cycles. It can be applied in the research and development field of special new materials, testing the impact test of new materials at specific temperatures, and has received high praise.
