9190A-DW-156 - FLUKE CALIBRATION

9190A Ultra-Cool

Field Metrology Well

Ultra-cool dry-block calibrator

with best-in-class stability Technical Data

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

pli

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.

demand strict quality control and regulatory process com-

ance. These applications include on-location validation

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 pharmaceuti-

cal, 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 heat-

ing times are faster than a calibration bath—that means calibration

work gets done more quickly.

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 tem-

perature 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 dry-

block 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.
