About the Fluke 9144-X-P
NB. 'X' in the model number to be replaced with A, B, C, D, E, or F as appropriate for the desired insert. See the inserts illustration and listing on the datasheet.
The Fluke 9144-X-P Field Metrology Well extends high performance to the industrial process environment by maximising portability, speed, and functionality with little compromise to metrology performance. The “Process” version (“9144-X–P”) combines the heat source with a built-in readout eliminating the need for the technician to take two instruments to the field.

|1. The temperature range may be limited by the reference probe connected to the readout. The Built-In Reference Thermometer Readout Accuracy does not include the sensor probe accuracy. It does not include the probe uncertainty or probe characterisation errors.|
2. Measurement accuracy specifications apply within the operating range and assume 4-wires for PRTs. With 3-wire RTDs add 0.05 ohms to the measurement accuracy plus the maximum possible difference between the resistances of the lead wires.
