Our product experts are here to help you find the right solution for your application!

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.

The 9190A is small and lightweight, making it easy to transport. And since it does not use heat transfer fluids, clean rooms stay clean.  It has a wide temperature range that is suitable for pharmaceutical, biomedical, and food processing applications.  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 dry-block development experience. The 9190A conforms with EURAMET cg-13 guidelines for best measurement practices for temperature block calibrators. As a result, you can be assured 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. 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.
