9142-C-156 Metrology Well Overview

The Fluke 9142 Field Metrology Well is lightweight, small, and quick to reach temperature set points, yet is also stable, uniform, and precise. It is useful for transmitter loop calibration, comparison calibration, or a simple check of a thermocouple sensor.

The unit is equipped with a large, easy-to-read LCD display, function keys, and menu navigation buttons. Its "SET PT" button makes it straightforward and simple to set the block temperature. In addition, it features a stability indicator that visually and audibly tells you the 9142 Field Metrology Well is stable to the selectable criteria. Its preprogrammed calibration routines are stored in memory for easy recall, and all inputs are easily accessible via the front panel of the instrument.

9140 Series Field Metrology Wells

Unlike traditional dry-wells, the 9140 Series Field Metrology Wells maximize speed and portability without compromising the six key metrology performance criteria laid out by the EA: accuracy, stability, axial (vertical) uniformity, radial (well-to-well) uniformity, loading, and hysteresis. All criteria are important in ensuring accurate measurements in all calibration applications. Field Metrology Well displays are calibrated with high quality traceable and accredited PRTs. Each device (process and non-process versions) comes with an IEC-17025 NVLAP-accredited calibration certificate, which is backed by a robust uncertainty analysis that considers temperature gradients, loading effects, and hysteresis. The units also accommodate various probe sizes with multiple-hole inserts.
