The PR551 series portable refrigeration thermostatic bath integrates functions such as temperature control, automatic temperature calibration, and precision measurement. It has excellent static and dynamic temperature control characteristics, built-in independent full-function temperature measurement channels and standard instrument measurement channels, and can edit complex calibration tasks. It can realize the full automatic calibration of thermocouples, thermal resistors, temperature switches, and electrical signal output temperature transmitters without other peripherals. It is very suitable for industrial sites and laboratories.

 Fully sealed design, no fear of medium spillage during transportation.

 Intelligent temperature control, the control algorithm automatically controls the working status of components such as heaters, refrigeration compressors, and cooling fans without manual intervention.

 Full-function electrical measurement channel, which can calibrate various thermal resistors, thermocouples, temperature transmitters and temperature switches.

 Reference temperature sensor, standard winding platinum resistance as reference temperature sensor.

 Editable task mode, which can realize the full automatic calibration process of multiple temperature calibration points.

 Support USB storage devices for easy export of calibration data.
