CALIBRATOR The Fluke 9143 Field Metrology Well extends high performance to the industrial process environment by maximizing portability, speed, and functionality with little compromise to metrology performance. It is packed with functionality and are remarkably easy to use. Moreover it is lightweight, small, and quick to reach temperature set points, yet it is stable, uniform, and accurate. This industrial temperature loop calibrator is 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.
