Our company provides necessary hardware for temperature control including temperature sensor, thermostat, heater or refrigerator. The main applications include ultra-high vacuum heating table, ultra-high vacuum steam source, heating device under atmosphere, low temperature thermostat in 77K temperature zone and 4K temperature low temperature thermostat. The temperature control range is 4K-2000K, of which the temperature control accuracy of 1.5K-77K temperature range is 1mk, and the temperature control accuracy of 77K-2000K temperature range is 0.1K. The temperature control can be closed-loop control or open-loop control. The closed-loop and open-loop can communicate with the computer to realize the remote control of temperature and the real-time collection of temperature data. The closed-loop temperature control mode can be selected as ON-OFF control mode, linear proportional control, PID control, etc. The temperature sensor can be selected from various thermocouple thermometers, resistance thermometers, diode thermometers, semiconductor thermometers, etc. it is suitable for different applications.
