The Hart Scientific 5612 PRT Temperature Probe may be calibrated in accordance with ITS-90, which makes it compatible with many excellent readout devices, including Hart’s 1575 and 1590 Super-Thermometers, 1560 Black Stack, and 1502 Tweener.

The 5612 bridges the gap between a 100-ohm industrial RTD and an SPRT. For those applications requiring fast thermal response, or where diameter and immersion depth are problems, order the 9-inch 5612.

These probes are excellent reference probes for comparison calibrations in a Hart dry-well. The 5612 may be calibrated from Tone196C to 420C.
