A thermometry assembly includes a thermometer and a mount for mounting the thermometer on a wall or other support structure. The thermometry assembly has an anti-theft system for deterring theft of the thermometer. The anti-theft system generally includes a counter that counts the number of uses of the thermometer during a period beginning from the time the thermometer was last on the mount. A microcontroller of the thermometer is programmed to disable further operation of the thermometer when a threshold number has been reached or exceeded by the counter. The counter is reset when the thermometer is returned to the mount. The anti-theft system includes a solid-state sensor that is activated by a magnet in the mount. The sensor signals to the microcontroller to reset the counter when it is activated by the magnet.
