The Fluke Calibration 9190A-A-P-156 Ultra-Cool Field Dry-Block Metrology Temperature Calibrator with Model 9190-INSA ("A" Insert) and Process Electronics is the most accurate and stable, cold temperature dry-block on the market. It is 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-A-P-156 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-A-P-156 is small and lightweight, making it easy to transport. There are no fluids, so cleanrooms stay clean. And the 9190A-A-P-156 cooling and heating times are faster than a calibration bath, which means that calibration work gets done more quickly.
