ABOUT THE FLUKE 9190A-X-P:
‘X’ in the above model numbers to be replaced with A, B, C, D, E, and F as appropriate for the desired insert.
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 Input Panel includes an input for an external reference/control thermometer that makes it possible to perform a transmitter loop calibration, comparison calibration, or a simple check of a temperature sensor. In addition, the Input Panel can read resistance and current from a probe. For probes that require power to operate, the 4-20 mA input has a loop-power function that can source up to 24 volts of power.
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.

 For ambient temperature of 23 °C.
 Time from when the SETPOINT is reached to when the unit is with in stability specification.
 The temperature range may be limited by the reference probe connected to the readout.
The built-in reference accuracy does not include the sensor probe accuracy. It does not include the probe uncertainty or probe characterisation errors.
 Measurement accuracy specifications apply within the operating range and assume 4 wires for PRTs. With 3-wire RTDs add 0.05 Ωto the measurement accuracy plus the maximum possible difference between the resistances of the lead wires.
 The thermocouple input readout is sensitive to EM fields in the frequency range of 500 MHz to 700 MHz.
