The Fluke Calibration 9190A 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, including 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 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.

The 9190A incorporates the best technology and design expertise gained from decades of dry-block development experience. It conforms to EURAMET cg-13, guidelines for best measurement practices for temperature block calibrators. Specifications for accuracy, stability, axial uniformity, radial uniformity, loading, and hysteresis have been thoroughly and carefully defined and tested. With a 9190A, you can be confident you're using the most accurate and stable ultra-cool dry-block calibrator available.
