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.

High performance for the industrial environment

Field Metrology Wells are designed for the industrial process environment. They weigh less than 8.2 kg (18 lb) and have a small footprint, which makes them easy to transport. Optimized for speed, Field Metrology Wells cool to –25 °C in 15 minutes and heat to 660 °C in 15 minutes.

Field environment conditions are typically unstable, having wide temperature variations. Each Field Metrology Well has a built-in gradient-temperature compensation (patent pending) that adjusts control characteristics to ensure stable performance in unstable environments. In fact, all specifications are guaranteed over the environmental range of 13 °C to 33 °C.

• Smallest dry-wells in the world
• Ranges from –10°C to 375°C
• Accuracy to ±0.25°C, stability of ±0.05°C at 0°C
• RS-232 interface with 9930 Interface-it v3.81 software
• Fluke Calibration's line of portable dry-wells is incredible. They’re the smallest, lightest, and most portable dry-wells in the world. And now they're better than ever!

• Range to 661°C
• Meets all ITS-90 requirements for resistance ratios
• Rtp drift < 20 mK after 500 hours at 661°C
• Calibrated accuracy of ± 0.006 °C at 0 °C
• Fluke Calibration's high-temp secondary standards fill the gap between affordable, but temperature-limited secondary PRTs (platinum resistance thermometers) and more expensive, highly accurate SPRTs (standard platinum resistance thermometers).

• Measure, graph and record three sensor types with one tool
  • The Fluke 1523 and Fluke 1524 Reference Thermometers from Fluke Calibration measure, graph, and record PRTs, thermocouples, and thermistors. These thermometer readouts deliver exceptional accuracy, wide measurement range, temperature logging, and trending, all in a handheld tool you can take anywhere.
    
  • The Fluke 1523 and Fluke 1524 let you handle field applications, laboratory measurements, and data logging with ease. And with the dual channel measurement capabilities of the model Fluke 1524, you can do twice the work in half the time.
