The Fluke 9143 Field Metrology Well is designed to be a reliable, stable heat source that can be used in the field or laboratory. It offers accuracy, portability, and speed for nearly every field calibration application. The instrument has been designed with the field user in mind and is easy to use while maintaining stability, uniformity, and accuracy comparable to some laboratory instruments.

The Fluke 9143-X 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 provides a built-in two-channel thermometer readout that measures PRTs, RTDs, thermocouples, and 4-20 mA transmitters which includes the 24 V loop supply to power the transmitter.

Each process version accepts an ITS-90 reference PRT. The built-in readout accuracy ranges from ± 0.01 °C to ± 0.07 °C depending on the measured temperature. Reference PRTs for Field Metrology Wells contain individual calibration constants that reside in a memory chip located inside the sensor housing, so sensors may be used interchangeably. The second channel is user-selectable for 2-, 3-, or 4-wire RTDs, thermocouples, or 4-20 mA transmitters.

The process option makes transmitter loop calibrations easy. The transmitter sensor is placed in the well with the reference PRT and the transmitter electronics are connected to the front panel of the instrument. With 24 V loop power, you are able to power and measure the transmitter current while sourcing and measuring temperature in the Field Metrology Well. This allows for the measurement of as-found and as-left data in one self-contained calibration tool.


Large LCD display is easy to see even in poorly lighted environments.
Function keys and easy-to-navigate menus.
Visual and audible stability indicator lets you know when you are ready to calibrate.
Pre-programmed calibration routines take the guesswork out of what to do.
One-button push to set the temperature.
Reference readout accepts “plug-and-play”.
