DTS-B Portable Smart Calibration Bath is a high-precision, self-regulating temperature calibration device. It features excellent stability, a uniform temperature field, and accurate temperature control. Utilizing a fully enclosed compressor refrigeration system and intelligent PID regulation, it achieves automatic temperature control. The unit has a compact structure, is lightweight, portable, and durable. It is suitable for on-site calibration/verification of various temperature sensors, including industrial platinum resistance thermometers, low-temperature thermocouples, sheathed thermocouples, working liquid-in-glass thermometers, standard mercury thermometers, bimetal thermometers, and pressure thermometers.

Product Features

Unaffected by ambient conditions: The -40 °C calibration point remains stable and unaffected in ambient temperatures ranging from 15 °C to 35 °C.

Intelligent rapid cooling: Cooling from 150 °C to 25 °C takes as short as 30 minutes and passes multi-cycle hysteresis testing.
Press-seal design: Features a quick-press sealing structure for leak prevention and convenient on-site transport.
Smart touchscreen interface: Equipped with an intelligent touchscreen and user-friendly interface. Temperature resolution is up to 0.001 °C.
Real-time curve display: Displays live temperature curves and automatically calculates stability.
Multi-point calibration: Supports calibration at multiple temperature points; temperature sensors allow segmented multi-point correction with fully automatic segmented control.
Communication functionality: Equipped with RS-232 communication port for connection with an upper-level host system.
