With the development of the semiconductor component industry, the performance testing of various electronic components in various complex environments has become prominent. High and low temperature testing machines are specialized equipment for simulating and testing the performance of electronic components in various environments.

The high and low temperature testing cold and hot integrated machine is mainly used to simulate high or low temperature experimental environments, conduct environmental adaptability and reliability tests during the transportation and storage of electronic technology products (including components, materials, and instruments), and can simultaneously test the electrical performance parameters of the test pieces when powered on. It is widely used in aviation, aerospace, electronics, national defense, scientific research and other fields.

The PTLD series low-temperature freezer mainly consists of a refrigeration system, a circulation system, a control system, a box, and so on. The refrigeration system adopts steam compression refrigeration, and the compressor and main refrigeration components are all from internationally renowned brands.

Semiconductor thermoelectric cooler, also known as semiconductor chiller, semiconductor temperature control console, precision semiconductor cooler, is composed of semiconductor refrigeration system, circulating water cooling system, temperature control system, and measuring fixture platform. Widely used in semiconductor industry etching devices, CMP laboratory precision devices, high-precision testing instruments, etc
