Fluke 9142-DW-P-156 Dry-Well Field Calibrator

Overview

The Fluke 9142-DW-P-156 is a portable field metrology well with integrated process electronics for temperature calibration. The -P designation indicates the presence of built-in readout capabilities for resistance, voltage, 4-20 mA current, and 24 V loop power, eliminating the need to carry additional tools into the field. The unit features fast temperature ramp rates, reaching temperature setpoints quickly while maintaining the stability and uniformity required for metrology-grade calibration.
