What to Look For When Choosing A Thermometer For Your Bearded Dragon

Choosing the right thermometer is not as easy as it sounds. It may get overwhelming when you see multiple products offering the same features at different prices.

However, we are here to guide you on how to prioritize your thermometer purchase.

Size Of Thermometer

Make sure to buy a thermometer according to the size of your enclosure. Some thermometers don’t give accurate readings in a large terrarium while working fine in a small one.

Response Time

Response time helps you to be as accurate as possible. Look for a thermometer that offers a quick response time.

Temperature Range

If you’re living in an area with extreme weather conditions, get a thermometer that has a high range for measuring temperature levels.

Attachment Technology

The thermometer’s attachment technology is very important. If your meter cannot stay attached, it’ll give you fluctuating temperature readings, which are of no use. Therefore, suction thermometers are better than adhesive ones.
