Fluke Calibration 9142-C-P-156 Field Metrology Well

Overview

The Fluke Calibration 9142-C-P-156 Field Metrology Well is a portable temperature calibration instrument enhanced with integrated process electronics. This P-series variant eliminates the need for external measurement devices by providing built-in readout for PRTs, RTDs, thermocouples, and 4-20 mA current loops, with integrated 24 V loop power supply. The combination of metrology-grade temperature control and direct sensor measurement makes it an all-in-one field calibration solution.

The unit maintains the excellent temperature stability and uniformity of the base 9142 design while adding automation capabilities for documentation and data logging. Its compact, portable form factor makes it suitable for demanding field calibration work where efficiency and accuracy are critical.
