Fluke 9172-DW-156 Metrology Well

Overview

The Fluke 9172-DW-156 is a laboratory metrology well designed for precision temperature calibration without a pre-installed insert. It provides temperatures from 35°C to 425°C with a calibrated display accurate to ±0.2°C at 425°C. With 203 mm (8 in) of immersion depth, the 9172 significantly reduces stem conduction errors at high temperatures. The unit features exceptional stability of ±0.01°C and minimal temperature gradients, making it ideal for calibrating RTDs, thermocouples, and thermistors in laboratory and field environments.
