Fluke 9170-DW-156 Metrology Well

Overview

The Fluke 9170-DW-156 is a precision metrology well designed for temperature calibration and measurement. 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 applications. The well features interchangeable probe sleeves and PRT-based temperature control, minimizing temperature gradients and loading effects for accurate, repeatable calibrations.
