The SANSEL Ultra Low Temperature Liquid Calibration Bath is designed for highly accurate temperature calibration in laboratories and industrial environments. Built with an advanced microcontroller-based system and auto-tune FUZZY PID control algorithm, this calibration bath delivers exceptional temperature stability, fast response, and precise control across ultra-low temperature ranges. The intuitive 4.3-inch TFT touch screen display allows users to monitor both set and liquid temperatures simultaneously for efficient calibration operations. Ideal for calibrating thermometers, thermocouples, RTDs, and temperature sensors, this system ensures reliable comparison with master RTD standards in pharmaceutical, research, food processing, and calibration laboratories.
