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

Home Engineering Electronic - Instrumentation & Control Ultra-Cool Field Metrology Well delivers ‘best-in-class’ stability

COMTEST is offering the Fluke 9190A Ultra-Cool Field Metrology Well, a small, lightweight, and accurate dry-block calibrator with what the company says is “best-in-class stability”.

It describes the 9190A as ideal for pharmaceutical, biomedical and food processing 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 9190A specifications for accuracy, stability, axial (vertical) uniformity, radial (well-to-well) uniformity, loading, and hysteresis have been thoroughly and carefully defined and tested,” the company said in a statement.

“It has a wide temperature range (-95 to 140 degrees Celsius) 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.”

It added that 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 (plus-or-minus 0.015 degrees Celsius) 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 plus-or-minus 0.02 degrees Celsius, and a reference sensor control to minimize the effects of the axial gradient when a reference PRT is aligned with short sensors.
