The Fluke 9190A ultra-cool field metrology well from Fluke Calibration provides excellent stability and uniformity and plenty of well depth for calibrating platinum resistance thermometers (PRTs), thermocouples and other industrial thermometers.

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, sterilisers (autoclaves), and freeze dryers.

The Calibrator has two models: the 9190A and the 9190A-P. The 9190A-P is a “Process” version of the 9190A that combines the heat source with a built-in thermometer input panel.


Dual heater zone: Active heater zone control compensates for differential temperatures between zones.
All controls and inputs on the front panel.
Two-handed carry; built-in handles on front and back. All controls and inputs on the front panel.
Define up to eight set-point temperatures; automatically ramp to and “soak” at each set-point.
Stability indicator: Indicates when the block temperature is stable and within limits defined by the user.
Fast time to temperature and small footprint: Uses compact, efficient free piston stirling cooler technology (FPSC).
Remote operation: USB and RS-232 communications interfaces support remote operation from a computer.
4-20 mA connectors: Power a 4-20 mA transmitter from the drywell. Supplies 24 V dc loop power (process version).
4-wire PRT/RTD input: Reads a 4-wire, 3-wire, or 2-wire PRT/RTD. Accuracy ±0.02 ºC (process version).
Reference thermometer input automatically reads Fluke Calibration PRTs terminated with a “smart” connector.
Thermocouple input: Accepts common thermocouples with mini-jack termination. Types: J, K, T, E, R, S, M, L, U, N, C.


Wide temperature range: –95 °C to 140 °C.
Accuracy using built-in reference thermometer readout:  ± 0.05 °C full range.
Display accuracy: ± 0.2 °C full range.
Best-in-class stability: ± 0.015 °C full range.
Fast cooling time: 23 °C to –90 °C: 80 min, 23 °C to –95 °C: 90 min, 140 °C to 23 °C: 60 min.
Portability: Weighs only 16 kg (35 lbs)
Best measurement practices: Conforms with EURAMET cg-13 guidance.
