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.

Process Electronics version.
Lightweight, portable, and fast.
Cool to -25°C in 15 minutes and heat to 350°C in 15 minutes.
Built-in two-channel readout for PRT, RTD, thermocouple, 4-20 mA current.
True reference thermometry with accuracy to ±0.01°C.
On-board automation and documentation.

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.
