Each xyzReptiles digital reptile thermometer is made from high quality electronics to ensure an accurate temperature reading. These futuristic and functional digital terrarium thermometers are a vital part of every reptile habitat. Our reptile thermometers are key in making sure that your reptile’s habitat is at the optimal ambient temperate. Providing the correct ambient temperature will help ensure that you have a healthy and happy reptile pet. Our reptile thermometer easily switches between Celsius and Fahrenheit with a pin push to suite your preference. The pinhole is located under the left side of the suction cup on the back of the thermometer. It also features a powerful suction cup to ensure a solid connection to your reptile pet’s terrarium so that it stays put. Pair it with our under tank heater (ideal for 10-15 gallon tanks) and create the perfect warm reptilian environment.
