Fluke 9142-D-P-156 Dry-Well Field Calibrator

Overview

The Fluke 9142-D-P-156 is a lightweight, portable field metrology well calibrator with Insert D metric probe holes (2×3mm, 2×4mm, 2×6mm) and built-in process electronics. This model is designed for temperature measurement and sensor calibration in field environments without needing to carry additional tools. The 9140 Series maintains the six key metrology performance criteria: accuracy, stability, axial uniformity, radial uniformity, loading, and hysteresis.

The unit features comprehensive process electronics including readout for resistance, voltage, 4-20 mA current, and 24 V loop power, making it ideal for transmitter loop calibration and comparison calibration work.
