iPower 8 by 12-Inch 16 Watts Reptile Heating Mat with Temperature Controller Under Tank Warmer Terrarium Heat Pad for Reptiles and Amphibians, Black

The Reptile Heat Pad is for indoor use only.

Do not submerge the heat pad for any reason.Inspect cord periodically.

Do not use if cord is damaged or frayed.

WARNING: Risk of Electric Shock.

The side mounting of the Reptile Heat Pad is the preferred application.

Please leave your pet heating pad with a cooling area.

Placement of Terrarium: Do not place on heat sensitive surfaces (i.e.

antique furniture, plastic, carpet, etc...)Do not place the terrarium where it may receive direct sunlight.

The heating pad uses positive temperature coefficient (PTC) ink technology, and its characteristic is that the resistivity increases as the temperature rises.

When the resistivity reaches a certain level, the resistance will effectively block the current and prevent further heating of the material, avoiding overheating, achieving self-heating temperature control.
