Fluke 9142-DW-156 Dry-Well Field Calibrator

Overview

The Fluke 9142-DW-156 is a lightweight, portable field metrology well calibrator without included inserts for temperature measurement and sensor calibration. It maintains the 9140 Series standards for accuracy, stability, uniformity, loading, and hysteresis. This model is ideal for users who already have compatible inserts or prefer to select specific probe hole configurations separately.

The 9142-DW-156 features two-channel readout capability for PRTs, RTDs, and thermocouples. The model accommodates various probe sizes through optional multiple-hole inserts available separately, supporting all standard insert configurations.
