Field metrology wells handle 660C environments

Hart Scientific 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 allows a turn-key solution for field calibration.

Each process version has a built-in reference thermometer readout that will accept reference probes with smart six-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 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.
