The Fluke 9103 Dry-Well Calibrator is designed for temperature calibrations below ambient conditions, offering a temperature range down to –25 °C under normal operating environments. It provides excellent performance with stability of ±0.02 °C and a display accuracy of ±0.25 °C across its entire range. Fast temperature transitions improve productivity, reaching 0 °C in just 8 minutes and 100 °C in approximately 6 minutes. The 9103 achieves temperatures up to 50 °C below ambient, allowing true sub-zero calibrations without requiring a cold room. It also offers flexibility through a range of interchangeable inserts, accommodating sensors from 1/16″ to 1/2″ diameter. Multiple insert options support single-sensor, comparison, and multi-sensor calibrations, making the instrument suitable for a wide variety of calibration applications.
