Fluke 9172-D-R-156 Metrology Well

Overview

The Fluke 9172-D-R-156 is a laboratory metrology well with integrated reference thermometry for precision temperature calibration and measurement. 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 and built-in Tweener reference measurement electronics, the 9172-D-R-156 significantly reduces stem conduction errors while enabling direct PRT readout with ITS-90 characterization coefficients.
