The Fluke Calibration 9102S-156 Low Temperature Handheld Dry-Well Temperature Calibrator (HDRC) is a small portable instrument designed for quick on-site checks and calibration of 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 -10°C to 122°C (14°F to 252°F). Temperature display and setpoint resolution are 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 transistor driven thermoelectric devices.

The Fluke Calibration 9102S-156 LED front panel 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.
