Fluke Calibration
Fluke Calibration 9142 Field Metrology Well
Model No :
Fluke Calibration 9142
Part Code :
3054130

Overview

The 9142 Field Metrology Wells extend high performance to the industrial process environment by maximizing portability, speed, and functionality with little compromise to metrology performance.
They are lightweight, small, and quick to reach temperature set points, yet they are stable, uniform, and accurate. With the “process” option, there is no need to carry additional tools into the field. This optional built-in two-channel readout reads resistance, voltage, and 4–20 mA current with 24 volt loop power. It also has on-board automation and documentation. Combined, the three models (9142, 9143, and 9144—each with a “process” option) cover the wide range of –25 °C to 660 °C.
