Fluke 9171-B-R-156 Metrology Well

Overview

The Fluke 9171-B-R-156 is a precision dry-block metrology well with an integrated built-in reference thermometer input. It provides 203 mm (8 inches) of immersion depth with temperature range from -30°C to 155°C and exceptional stability of ±0.005°C across the full range. The built-in reference input can accommodate 100-, 25-, and 10-ohm PRTs and accurately reads thermometer probes from ±0.006°C at 0°C to ±0.027°C at 661°C, making it suitable for use as a reference standard.
