Fast, portable industrial temperature calibration

Three models of the new Field Metrology Wells make temperature sensors and transmitter calibrations simple with built-in thermometer readout and onboard automation and documentation

Fluke - Hart Scientific, a world leader in temperature calibration products and services, has introduced the 9140 series Field Metrology Wells designed for optimum performance and functionality over the range of -25C to +660C.

Unlike traditional field dry-wells, the new Field Metrology Wells maximise speed and portability without compromising key metrology performance criteria such as stability to +/-0.01C, radial uniformity to +/-0.01C, axial uniformity at 40mm to +/-0.04C, loading to +/-0.006C, and hysteresis to +/-0.015C.

The units weigh about 7.3kg and will reach 660C 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 characterisation in the connector.

The built-in reference readout has a second channel which will measure resistance, voltage, or 4-20mA 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.

Field Metrology Wells have a dedicated temperature set point and C/F buttons.

Pre-programmed tasks and temperature points can easily be saved and recalled for pre-routed calibrations.

All inputs and terminals are located on the front of the unit for easy access.
