Hart Scientific Model 3125 Surface Calibrator

Surface probes are difficult to calibrate because it's hard to find a flat, heated surface that's stable and uniform. The Hart Scientific Model 3125 surface calibrator takes advantage of the proprietary Hart Scientific 2200 temperature controller and gives you the best possible conditions for calibrating surface sensors.

Why buy a non-temperature calibration device designed for test tube sterilization or PC board repair when you can have a true calibration instrument? The Hart Scientific Model 3125 surface calibrator has a uniform surface temperature and reaches temperatures as high as 400 degrees C.

The Hart Scientific Model 3125 surface calibrator's test surface is milled aluminum for an absolutely smooth and true calibration work area with maximum thermal conductivity. The 12.25-square-inch test surface is large enough to calibrate more than one sensor at a time. The Hart Scientific Model 3125 surface calibrator can be used with a reference surface sensor or PRT. PRTs (3/16" diameter) may be inserted through a drilled hole into the center of the block for use as reference thermometers or for easy recalibration of the unit's display.

With an accuracy of +/-0.5 degrees C to 200 degrees C and +/-1 degrees C to 400 degrees C, you can use the Hart Scientific Model 3125 surface calibrator to calibrate almost any surface probe, thermistor, thin film sensor, RTD, thermocouple, ribbon sensor, or surface mount cutouts, fuses, and switches. The Hart Scientific Model 3125 surface calibrator's stability is within +/-0.3 degrees C at 400 degrees C, and uniformity within the center three inches of the surface is +/-0.6 degrees C at 200 degrees C.
