(Fluke Corp.: Everett, WA) --  Electronic test-and-measurement technology provider Fluke Corp. has introduced the 1594A/1595A Super-Thermometers from Hart Scientific, designed to combine accuracy, value, and innovative features for calibrating SPRTs, PRTs, and thermistors.

The Fluke 1594A and 1595A Super-Thermometers are accurate enough for the primary lab, providing accuracy as good as 0.06 ppm (0.000015 °C), and economical enough for the secondary lab. Measurements made with the super-thermometer fall within expected limits and are easily verified. Their features include:

Ratio self-calibration. The 1594A and 1595A feature “ratio self-calibration” that enables users to test the accuracy or calibrate the resistance ratio linearity of the super-thermometer’s measurement circuit—without requiring external devices or special training. Metrologists can verify accuracy and performance automatically in about 30 minutes at the touch of a button. Although unlikely, measurement-circuit defects would be detected and reported automatically.
