Fluke 9143-D-156 Field Metrology Well

Overview

The Fluke 9143-D-156 is a portable Field Metrology Well for industrial process environments, providing temperature calibration from 33°C to 350°C with metrology-grade performance. Designed for field portability without compromising accuracy, it delivers metrology performance across all six EA criteria: accuracy, stability, axial uniformity, radial uniformity, loading, and hysteresis. The metric Insert D accommodates standard metric probe sizes for comparison calibrations.
