Thermometry bridge accuracy combined with time-saving features

The Fluke Calibration 1594A and 1595A Super-Thermometers combine the accuracy of complex and expensive bridges with innovative features that simplify measurement processes and provide excellent value. They are accurate enough for the primary lab and economical enough for the secondary lab. With temperature-controlled internal reference resistors, six input channels, a large graphical display, and a multitude of temperature-specific measurement functions, PRT, thermistor and SPRT calibration (0 Ω to 500 kΩ) has never been so easy and economical. And with the built-in Ratio Self-Calibration function, you can verify or calibrate the Super-Thermometer’s ratio accuracy in-house with the press of a button—no other single thermometry bridge can do so much, so well!
