China [CN] Vacuum System: Includes vacuum container, vacuum pump (primary/secondary) and valve components, capable of achieving an ultimate vacuum level of 10-*Pa. For example, a certain model of equipment from China Instrument Network uses a secondary ionization silicon digital display vacuum level, with an accuracy of ±0.001Pa.
Temperature Control System: Achieves wide temperature range control through heat sink and high/low temperature regulation devices. The typical range is -70℃ to 180℃, and the temperature uniformity can reach ±0.8℃ to 2℃. Some high-end equipment adopts dual closed-loop PID temperature control and fuzzy adaptive algorithms, such as Beijing Yashilin equipment, which can control the accuracy within -80℃ to 180℃ temperature range to ±0.3℃.
Measurement and Control Safety System: Integrates PLC control system, data acquisition module (such as PT100 thermocouple) and multiple protection devices (overvoltage relief, ammonia pressure monitoring, etc.). The equipment from China Instrument Network supports 30 temperature step programming, 100 cycle settings, and has USB data export function.If you need more models about our test equipment, please reference our ： chamber-testing（Click）com
