Fluke 9144-DW-P-156 Dry-Well Field Calibrator

Overview

The Fluke 9144-DW-P-156 is a portable field metrology well with integrated process electronics for comprehensive on-site temperature calibration. It provides accurate, stable temperature control from 50°C to 660°C, making it ideal for industrial transmitter loop calibration and sensor verification outside the laboratory. Unlike traditional dry-wells, it maximizes speed and portability while maintaining superior metrology performance across accuracy, stability, and uniformity.
