The Fluke Calibration 9100S-B-156 Handheld Dry-Well Temperature Calibrator with Block "B", 35 °C to 375 °C (95 °F to 707 °F) may be used as a portable instrument or bench top temperature calibrator for calibrating thermocouple and RTD temperature probes. This instrument is small enough to use in the field, and accurate enough to use in the lab. Calibrations may be done over a range of 35°C to 375°C (95°F to 707°F). Temperature display resolution is 0.1 degrees.

The temperature is accurately controlled by Fluke's digital controller. The controller uses a precision platinum RTD as a sensor and controls the well temperature with a triac driven heater.

The Fluke Calibration 9100S-B-156 LED front panel continuously shows the current well temperature. The temperature may be set, using the control buttons, to any desired temperature within the instrument's range. Multiple fault protection devices insure user and instrument safety and protection.
