The new 914X Series Field Metrology Wells extend high performance to the industrial process environment by maximizing portability, speed, and functionality with little compromise to metrology performance. Field Metrology Wells are packed with functionality and are remarkably easy to use. They are lightweight, small, and quick to reach temperature set points, yet they are stable, uniform, and accurate. These industrial temperature loop calibrators are perfect for performing transmitter loop calibrations, comparison calibrations, or simple checks of thermocouple sensors. With the “process” option, there is no need to carry additional tools into the field. This optional built-in two-channel readout reads resistance, voltage, and 4 – 20 mA current with 24 volt loop power. It also has on-board automation and documentation. Combined, the three models (Fluke 9142, Fluke 9143, and Fluke 9144—each with a “process” option) cover the wide range of –25°C - 660°C.

• Lightweight, portable, and fast
• Cool to –25°C in 15 min and heat to 660°C in 15 min
• 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
• Metrology performance in accuracy, stability, uniformity, and loading
