Fluke Calibration 9190A Field Metrology Well

The Fluke Calibration 9190A Field Metrology Well (formerly Hart Scientific) 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.

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.

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.
