Solar LCD Digital Thermometer for Fish Tank Tropical Marine Aquarium Temperature

The solar powered digital thermometer can be used during the day and can be powered by the natural daylight. The solar thermometer then converts the natural and artificial light into energy in order to power the thermometer. It also stores the excess energy that it has gathered so that during the night it can continue to work, even in complete darkness! The high precision aquarium thermometer is accurate to within 1 degree. Can be set to display your Aquarium temp in °C or °F with the push of a button.
