Calibration baths are the most stable and uniform temperature sources manageable, but they arent a good fit for tidy rooms. The size of a bath limits its portability, and bath fluids can easily spill and find the money for off vapors. The 9190A Ultra-Cool Field Metrology Well is a amenable stand-in. Its broad temperature range brackets the coldest and highest temperature ranges required for pharmaceutical, biomedical and food running applications. The 9190A is little and lightweight, making it easy to transport. And past it does not use heat transfer fluids, tidy rooms stay tidy. The 9190A cooling and heating era are faster than a calibration baththat means calibration be alert gets finished more speedily.
Unreliable process measurements can have a damaging impact on the subject of matter, leading to poor product mood, recalls, fines, waste, and drifting profits. Ultimately, measurements are single-handedly as gigantic as the temperature sources used to calibrate the measurement equipment. The 9190A Ultra-Cool Field Metrology Well incorporates the best technology and design high flier gained from decades of abstemious-block loan experience. The 9190A conforms following EURAMET cg-13 guidelines for best measurement practices for temperature block calibrators. As a upshot, you can be assured that the 9190A specifications for precision, stability, axial (vertical) uniformity, radial (skillfully-to-dexterously) uniformity, loading, and hysteresis have been thoroughly and purposefully defined and tested. With a 9190A Ultra-Cool Field Metrology Well, you can be confident youtaking into account suggestion to using the most accurate and stable ultra-unapproachable abstemious-block calibrator user-easily reached. And that will have a certain impact on the order of your affect.
Ultra-cool dry-block calibrator with best-in-class stability
The Fluke 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.
