Model 5626 reference-grade platinum-resistance thermometer fromHart Scientific Inc.retains the integrity of its sensing element to 1,220oF (660oC). The sensor is designed similar to a primary standards-level SPRT to remain stress-free at high temperatures and resist contamination of its platinum element. Measurement uncertainty after calibration is within +/-0.01oC, and a full NIST-traceable calibration report is included.
