Fluke 9173-A-156 Metrology Well Calibrator

Overview

The Fluke 9173-A-156 is a precision metrology well configured with an aluminum-bronze Insert A, designed for high-temperature calibration of thermometers, RTDs, thermocouples, and thermistors. It minimizes temperature gradients, loading effects, and hysteresis while delivering exceptional display accuracy of ±0.25°C at 700°C. The Insert A features multiple probe hole sizes (3/16", 1/8", 1/4", and 3/8") to accommodate various probe diameters.
