Fluke 9144-X-P-256 Field Metrology Well w/ Process Electronics & Disc
The Fluke 9144-X-P-256 Field Metrology Well with Process Electronics and Selectable Disc is available in seven models; these models differ only in regards to their selectable discs. For further information regarding these models and their selectable discs, please see the table below.

Each of these models functions as an alternative to dry well temperature calibrators and has a temperature range of 50-660°C. The Fluke 9144-X-P-256 takes just fifteen minutes to heat to the highest temperature from the lowest and remains stable to ±0.05°C at 660°C; each model is fitted with a stability indicator which visually and audibly alerts the user to the product’s stability. In addition to this, ±0.01°C uniformity performance is maintained by thermal block characteristics, whilst the dual-zone control helps to facilitate an axial uniformity of ±0.05°C at 40mm.
Despite its lightweight, compact size and quick operational procedures the Fluke 9144-X-P-256 Field Metrology Well fulfils metrology performance criteria as specified by EA:
- Accuracy
- Stability
- Axial (vertical) uniformity
- Radial (well-to-well) uniformity
- Loading
- Hysteresis
Fluke Calibration’s 914X-X-P-256 models are all calibrated using high-quality, traceable, accredited PRTs and are supplied with IEC 17025 NVLAP accredited calibration certificates. These certificates are informed by thorough uncertainty analysis which takes into consideration temperature gradients, loading effects and hysteresis. As a result, the Fluke 9144-X-P-256 Field Metrology Well has a display accuracy of ±0.35°C at 420°C and ±0.5°C at 660°C.
In addition to the Fluke 9144-X-P-256’s practicality, speed and accuracy, it is also easy-to-use. It features characteristics such as menu navigation buttons and function keys which help to facilitate easy access, via the front panel, to the field metrology well’s inputs as well as its pre-programmed calibration procedures. Its ‘SET PT’ button allows the user to set the block temperature quickly and easily, while the large, easy-to-read LCD display ensures that the user is able to see and record measurements.
Like the simpler version of this temperature calibration instrument, the Fluke 9144-X-256 Field Metrology Well (available here), the Fluke 9144-X-P-256 Field Metrology Well with Process Electronics features auto and manual setup of automated thermostatic switch test procedures. The auto-setup only requires the user to enter the nominal switch temperature in order to run an automatic three-cycle calibration procedure which will provide the user with a final result for the dead band temperature, whilst the manual-setup allows the user to customise the calibration procedure, for example by adding additional cycles or altering the ramp rate.
Where this instrument differs from the aforementioned Fluke 9144-X-256 is the inclusion of integrated process electronics which facilitates a number of functions not available on the non-process electronics model. See below for further details.
Two-Channel Thermometer Readout
The two-channel thermometer readout has an accuracy of ±0.01°C to ±0.07°C depending upon the temperature being measured and is capable of checking PRTs, RTDs, thermocouples and 4-20mA transmitters with 24V loop supply to the power transmitter. This instrument will accept ITS-90 reference PRTs. The metrology well's reference PRTs contain calibration constants stored in a memory chip located within the sensor's housing, allowing sensors to be used interchangeably. Further to this, the second channel of the Two-channel Thermometer Readout is user selectable for 2-,3- or 4-wire RTDs, thermocouples, or 4-20mA transmitters, thereby allowing the user to perform comparison calibration using a single test instrument.
Transmitter Loop Calibrations
The Fluke 9144-X-P-256 Field Metrology Well’s ability to perform transmitter loop calibrations helps to reduce the 75% of errors caused by uncalibrated transmitter sensors. The user can calibrate the transmitters’ electronics and sensors by placing the sensor in the well with the reference PRT and connecting the electronics to the front panel, by doing this the user is able to power and measure transmitter current while sourcing and measuring temperature, providing the user with as-found and as-left data.
On-Board Non-Volatile Memory
This feature allows the instrument to function as a turnkey solution, providing memory space to record up to twenty tests along with each test's unique alphanumeric ID, block temperature, reference temperature, UUT values, error, date and time. This information can be viewed using the front panel, or the raw data can be exported into calibration reports or ASCII files using the included Model 9930 Interface-It Software.
The Fluke 9144-X-P-256 Field Metrology Well with Process Electronics and Selectable Disc Insert’s eclectic array of features and practical, ergonomic physical design make it suitable for temperature calibrating 4-20ma transmitters with or without 24V loop supply to the power transmitter; simple thermostatic switches and a number of other sensor types.
