Field Metrology Well

Ultra-cool dry-block calibrator

with best-in-class stability

The Fluke Calibration 9190A Ultra-Cool Field Metrology
Well is the most accurate and stable, cold temperature
dry-block on the market. It’s ideal for applications that
demand strict quality control and regulatory process com­pliance. These applications include on-location validation
and calibration of RTDs, thermocouples, thermometers,
and sensors used with process control equipment such
as medical freezers, laboratory refrigerators, cold rooms,
blood banks, sterilizers (autoclaves), and freeze dryers.

Great for cleanroom environments

Calibration baths are the most stable and uniform temperature
sources available, but they aren’t a good fit for cleanrooms. The
size of a bath limits its portability; it uses fluids that produce fumes
that can easily be spilled. The 9190A Ultra-Cool Field Metrology
Well is a great alternative. Its wide temperature range brackets the
coldest and highest temperature ranges required for pharmaceuti­cal, biomedical and food processing applications. The 9190A is
small and lightweight, making it easy to transport. There are no
fluids so cleanrooms stay clean. And the 9190A cooling and heat­ing times are faster than a calibration bath—that means calibration
work gets done more quickly.

Technical Data

An accurate temperature source is critical for
dependable process measurements

Unreliable process measurements can have a damaging impact on
business, leading to poor product quality, recalls, fines, waste, and
lost profits. Ultimately, measurements are only as good as the tem­perature sources used to calibrate the measurement equipment.

The 9190A Ultra-Cool Field Metrology Well incorporates the
best technology and design expertise gained from decades of dry­block development experience. The 9190A conforms to EURAMET
cg-13, guidelines for best measurement practices for temperature
block calibrators. As a result, 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. With a 9190A Ultra-Cool Field Metrology Well, you can
be confident you’re using the most accurate and stable ultra-cool
dry-block calibrator available. And that will have a positive impact
on your business.
