Fluke 9171-E-R-156 Metrology Well

Overview

The Fluke 9171-E-R-156 is a precision dry-well calibrator designed for high-accuracy temperature measurement and sensor calibration. Offering 203 mm (8 in) of immersion depth and operating from -30°C to 155°C, it provides display accuracy of ±0.1°C and exceptional full-range stability of ±0.005°C. The -R variant integrates built-in reference thermometry using Fluke's Tweener technology, enabling independent PRT measurement while Insert E accommodates metric probe sizes.
