Fluke/Hart Intros Field Metrology Wells
Field metrology well.
American Fork, UT — Hart Scientific, a division of Fluke Corporation, has introduced the 9140 series Field Metrology Wells designed for optimum performance and functionality over the range of -25 to +661°C.

Unlike traditional field dry-wells, the new Field Metrology Wells maximize speed and portability without compromising key metrology performance criteria such as stability to ±0.01°C, radial uniformity to ±0.01°C, axial uniformity at 40mm to ±0.04°C, loading to ±0.006°C, and hysteresis to ±0.015°C. These units weigh about 16 lbs. and will reportedly reach 660°C in less than 15 minutes.

The Field Metrology Well "process" option makes possible a turn-key solution for field calibration. Each process version has a built-in reference thermometer readout that will accept reference probes with smart 6-pin DIN connectors which store probe characterization in the connector. The built-in reference readout has a second channel which will measure resistance, voltage, or 4-20 mA current. The process version provides 24V loop power for calibration of temperature transmitters. With every calibration, the process version of Field Metrology Wells can automate and document as-found and as-left data from the reference probe and the unit under test. Each unit has an LCD display and menu driven interface, and have a dedicated temperature set point and °C/°F buttons. Pre-programmed tasks and temperature points can easily be saved and recalled for route calibrations. All inputs and terminals are located on the front of the unit for easy access.
