Fluke 9170-D-R-156 Metrology Well

Overview

The Fluke 9170-D-R-156 is a precision metrology well designed for temperature calibration and measurement applications. This model achieves the lowest temperatures in the 9170 series, reaching -45°C in normal room conditions. With exceptional stability of ±0.005°C across its full temperature range (up to 140°C) and an immersion depth of 160 mm, it delivers precise temperature calibration for laboratory and field use. The model includes built-in reference thermometer input using Fluke's Tweener measurement technology, enabling direct connection and measurement with precision PRTs.
