Monnit wireless water temperature sensor use a 3 foot external water sealed sensor probe to measure temperatures in water or non-combustible liquids. Perfect for monitoring temperatures in water storage tanks, pools, aquariums and natural wet-life environments. User customization allows you to set the frequency of readings and the ability to set conditions for text and/or email notifications from the system.
* Actual range may vary depending on environment.
** Battery life is determined by sensor reporting frequency and other variables.
