Fluke 9173-D-R-156 Metrology Well

Overview

The Fluke 9173-D-R-156 is a high-performance metrology well designed for precision calibration of thermometers from 50°C to 700°C. With display accuracy of ±0.25°C at 700°C and an immersion depth of 203 mm (8 inches), it provides excellent temperature control for demanding calibration applications. The unit features built-in reference thermometer input using Fluke's Tweener technology, which accommodates 100-, 25-, and 10-ohm PRTs and provides highly accurate readings from ±0.006°C at 0°C to ±0.027°C at 661°C.
