Calsys 250 Portable, Lightweight, Highly Accurate Liquid Calibration Bath For Industrial/laboratory Field Use 

CALsys 250 offers easy to use portable temperature calibrator with high temperature range from 250 to 250C. It is a highly stable standard furnace for calibrating thermocouples / RTD. It provide superior thermal environment for probe immersion as no air gape exist between the probe and the medium, thermal coupling is therefore much better than the alternatives described and the stirring results in very even heat distribution throughout the medium. Methanol is used for temperature below 0 deg c water from 0 to 80 and silicon oil up to 250. We have seven types of liquid baths. The comparison volume is a diameter of 90 mm and 140 mm depth. The temperature of the calibrator is set and controlled by a self tuned PID controller with automatic super fine adjustment.
