Fluke Calibration 9144-A High Temperature Dry-Well Calibrator

Overview

The Fluke Calibration 9144-A is an advanced high-temperature field metrology well for comprehensive temperature sensor and transmitter calibration in industrial environments. Covering 50°C to 660°C, this metrology-grade dry-block calibrator includes a built-in two-channel thermometer readout for measuring PRTs, RTDs, thermocouples, and 4–20 mA transmitters with 24 V loop power. This single-instrument solution eliminates the need to carry multiple tools to the field.
