EMR963HG - Wireless Temperature & Humidity Meter with 1 Remote Sensor
Set high and low alarms for temperature and humidity. An alarm condition causes the display to flash on and off and an audible alarm to sound for one minute. After one minute, the audible alarm stops in order to conserve battery life, but the display continues to flash on and off until any button has been pressed. Alarms can be disabled if desired. It’s great for monitoring coolers, refrigerators and freezers, computer equipment and more.

Just place the smaller remote sensor outdoors, in your computer room, in your cooler or wherever you want to monitor a remote temperature then place the base unit in a convenient location. You'll then be able to view the remote and local temperatures at the same time. You can add up to two additional remote sensors and monitor 3 remote locations at once.
