WeatherHawk’s myBlue-T temperature monitoring tag can be used anywhere you need to know the current temperature. It is waterproof to 3 feet, so use it hiking, camping, in coolers, in hot tubes, pools, the babies bath water, saunas, outside a window, indoors, or anywhere knowing temperature is important. This App allows you to connect to up to five myTemp-T tags at a time for current and min/max temperature during the time the App is connected. Customize the name of a tag on your mobile device, and even change the units of measure. Monitoring ambient temperature has never been so convenient.
