Fluke 9142-X-P Process Field Metrology Well

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 9142 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 9142-X-P Field Metrology Well extends high performance to the industrial process environment by maximizing portability, speed, and functionality with little compromise to metrology performance. The “Process” version (“9142-X-P”) combines the heat source with a built-in readout eliminating the need for the technician to take two instruments to the field. The process option includes a readout for resistance, voltage, 24V loop power and 4 - 20 mA current with on-board documentation, eliminating the need for a separate computer. With this option there is no need to carry around extra process calibration tools. The 9142 LCD display continuously shows many useful operating parameters including the block temperature, the current set-point, block stability, and heating and cooling status. For the Process version, the reference temperature and secondary input type (UUT) readings are displayed. The display can be set to show the information in one of eight different languages; English, Japanese, Chinese, German, Spanish, French, Russian and Italian.
