Fluke 9173-B-R-156 Metrology Well

Overview

The Fluke 9173-B-R-156 is a high-performance metrology well designed for temperature calibration between 50°C and 700°C. With 203 mm (8 inches) of immersion depth, exceptional stability and uniformity, and a built-in reference thermometer input (Tweener technology), this unit minimizes temperature gradients and loading effects for highly accurate thermometer calibrations. Insert B accommodates comparison holes in multiple standard sizes.
