Ultra-Cool Field Metrology Well delivers best-in-class stability

March 2016 Maintenance, Test & Measurement, Calibration

Fluke has introduced the 9190A Ultra-Cool Field Metrology Well – a small, lightweight and accurate dry-block calibrator with best-in-class stability. The instrument is ideal for food processing, pharmaceutical and biomedical applications that demand strict quality control and regulatory process compliance, including 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 ensures that the specifications for accuracy, stability, axial (vertical) uniformity, radial (well-to-well) uniformity, loading, and hysteresis have been thoroughly and carefully defined and tested.

It has a wide temperature range (-95°C to 140°C) to cover the coldest and warmest temperatures required in pharmaceutical, biomedical and food processing applications, operating at ultra-cold temperatures not typically available with a calibration bath. The 9190A uses no bath fluids, keeping clean rooms clean, making it easier to transport, and delivering faster heating/cooling rates. It offers best-in-class temperature stability for consistent, accurate results.

The 9190A with ‘process’ option features 4-20 mA connectors, a reference thermometer input, 4-wire PRT/RTD input with an accuracy of 0,02°C, and a reference sensor control to minimise the effects of the axial gradient when a reference PRT is aligned with short sensors.
