DIGITAL AQUARIUM THERMOMETER

It has a high and low temperature alarm function which is set at 28°C for the high limit and 18°C for the low limit.

This thermometer should be fixed onto the outside glass of the aquarium, making sure that the metal part at the back is placed a few centimetres below the water line so that the water temperature is as accurate as possible.

Furthermore, as this thermometer is placed on the glass outside the aquarium, it will not be covered by algae. So there is no need to clean it to check the temperature!

IMPORTANT
Avoid contact with water and never immerse the thermometer in water. This would make it unusable!
