Fluke Calibration 9100S Handheld Dry-Well

The Fluke Calibration 9100S Handheld Dry-Well is a compact dry-block temperature calibrator designed for portable calibration and verification of temperature sensors. Its small footprint and lightweight construction make it particularly suitable for field technicians who need a stable temperature source without the size of a conventional laboratory dry-well.

Compact Temperature Calibration for Field Applications

The 9100S is designed for checking RTDs, thermocouples and small bimetal thermometers. Front-panel controls allow users to set the desired temperature directly, while the built-in display provides a convenient way to compare the calibrator temperature with the reading from the device under test or an external reference thermometer.

Its compact dimensions of approximately 57 × 125 × 150 mm and weight of about 1 kg make it practical for mobile calibration work, maintenance teams and service engineers working away from a laboratory environment.

Stable and Repeatable Temperature Performance

The 9100S uses a Fluke Calibration temperature controller to provide controlled and repeatable temperature conditions. The unit stabilizes in approximately 5 minutes, while heating from 35 °C to 375 °C takes approximately 9.5 minutes.

Portable Dry-Well for Temperature Sensor Verification

Unlike multifunction process calibrators that electrically simulate temperature signals, the 9100S provides a controlled physical temperature source for testing temperature sensors and thermometers. This makes it useful when the sensor itself needs to be inserted into a stable temperature environment for comparison against a reference.

The 9100S uses a 102 mm deep well, with a 1.6 mm hole extending 89 mm deep, allowing compatible temperature probes to be positioned within the controlled heating block.

RS-232 Connectivity and Calibration Data

An RS-232 interface is included for connectivity, supporting integration with calibration workflows. The 9100S also has NIST-traceable calibration data available at multiple temperatures across its operating range, supporting documented temperature calibration applications.
