Fluke Calibration 9100S Handheld Dry-Well

Compact. Powerful. Field-Ready.

9100S Dry-Well, The Original Handheld Calibrator

The Fluke 9100S was the world’s first truly handheld dry-well, and it continues to set the standard for portable temperature calibration. Many have attempted to replicate its compact size and performance—but none have succeeded.

Ultra-compact: Only 2¼ inches high and 5 inches wide
Lightweight and durable: Built for demanding field environments
Outperforms every dry-well in its class worldwide

Fast, Easy, and Accurate

Designed with simplicity in mind, the 9100S is easy to operate—most users are up and running in less than 15 minutes.

Temperature Range: Up to 375 °C (707 °F)
Ideal for checking RTDs, thermocouples, and small bimetal thermometers
Front-panel buttons allow easy temperature setting
Compare readings using the built-in display or an external reference thermometer
