Fluke Calibration 9190A Ultra-Cool Field Metrology Well

The 9190A Ultra-Cool Field Metrology Well from Fluke Calibration is a small, lightweight dry-block calibrator.

The 9190A is suitable for pharmaceutical, biomedical and food processing applications that demand strict quality control and regulatory process compliance. This includes on-location validation and calibration of RTDs, thermocouples, thermometers and other temperature sensors.

The 9190A conforms to EURAMET cg-13 guidelines for best measurement practices for temperature dry-block calibrators. This means its specifications for accuracy, stability, axial (vertical) uniformity, radial (well-to-well) uniformity, loading and hysteresis have been thoroughly and carefully defined and tested.

The 9190A has a wide temperature range (-95 to 140°C) to cover the coldest and warmest temperatures required in pharmaceutical, biomedical and food processing applications. Operating at ultracold temperatures is not typically available with a calibration bath. The 9190A uses no bath fluids, which keeps cleanrooms clean, makes it easier to transport and delivers faster heating/cooling rates. It offers temperature stability of ±0.015°C for consistent and accurate results.

The 9190A with ‘process’ option features 4-20 mA connectors, a reference thermometer input and a 4-wire PRT/RTD input with an accuracy of ±0.02°C. It also has a reference sensor control to minimise the effects of the axial gradient when a reference PRT is aligned with short sensors.
