Fluke 9172-B-R-156 Metrology Well

Overview

The Fluke 9172-B-R-156 is a precision dry block metrology well with integrated reference thermometry for complete temperature calibration. It provides stable, accurate temperatures from 35°C to 425°C with display accuracy of ±0.2°C at 425°C and exceptional stability of ±0.005°C to ±0.01°C. The integrated Tweener measurement technology eliminates the need for separate external reference thermometers, accommodating 100-, 25-, and 10-ohm PRTs with integrated reference accuracy from ±0.006°C at 0°C to ±0.027°C at 661°C.
