Frequently Asked Questions

Q: How do I install the 3D Digital LED Aquarium Thermometer?

A: Simply peel off the adhesive backing and stick the thermometer firmly to the outside surface of your aquarium glass. Once in place, pull out the transparent insulation sheet from the back of the LCD screen to activate the display. The digital readout will begin showing temperature readings within moments.

Q: Can I use this thermometer inside the water?

A: No — this thermometer is designed exclusively for external use. Attach it to the outside of the glass or acrylic wall of your tank. Submerging the unit may damage it and void any functionality.

Q: How accurate is the temperature reading?

A: Because the sensor reads through the tank wall (glass or plastic), readings may differ from actual water temperature by approximately 2–5 °C. The reading should be treated as a helpful reference guide rather than a laboratory-precise measurement.

Q: Is this thermometer suitable for turtle tanks and reptile enclosures?

A: Yes! The thermometer works with any tank or enclosure that has a glass or clear plastic wall, including fish tanks, turtle habitats, reptile terrariums, and similar setups.
