The 3125 takes advantage of the 2200 Temperature controller to deliver the best conditions for calibrating surface sensors. It can be used with a reference surface sensor or PRT. PRTS may be inserted into a hole in the centre of the block for use as reference thermometers or for calibration of the unit’s display.
Temperature range is 35°C to 400°C, with stability within ±0.3°C.The unit can calibrate almost any surface probe, thermistor, thin film sensor, RTD, thermocouple, ribbon sensor, or surface mount cutouts, fuses, and switches.
