Fluke 9140 | Field Dry-Well Calibrator 35°C to 350°C

Routine plant calibration often involves RTDs, thermocouples and switches operating well above ambient temperature but below the range of furnace-grade calibration equipment. The Fluke Calibration 9140 Field Dry-Well Calibrator provides a portable 35°C to 350°C temperature source for this common process range.

The catalogue states accuracy to ±0.25°C and stability to ±0.02°C. The heating rate can be adjusted from the front panel, allowing technicians to control how quickly the unit approaches a calibration point. The 9140 also supports thermal-switch actuation testing and offers interchangeable multi-hole inserts for different probe sizes. An RS-232 interface facilitates communication, while NIST-traceable calibration supports professional metrology and maintenance requirements.

Mid-Temperature Dry-Well Selection Guide

Choose the 9140 for portable calibration between 35°C and 350°C. Select the 9103 for below-ambient operation.
