Thermometers help ensure that your beardie’s tank is at the optimal temperature. The best bearded dragon thermometer is actually having two thermometers!

Check out our guide below for recommendations and how to use bearded dragon thermometers properly.

In this guide, you’ll learn:

  • Which bearded dragon thermometer do you need?
  • Why do you need a thermometer?
  • How to properly use a thermometer in your beardie’s tank.

Pro-tip

We recommend owning 2 thermometers– one to keep at the warmer, basking section of your tank and one for the cooler area of your bearded dragon’s enclosure. It’s also a good idea to own a spot check thermometer for quickly checking the accuracy of each section in your tank.

Maintaining the recommended temperature in your bearded dragon’s tank accurately is essential for its health and a good thermometer is required to monitor this. A lot of your bearded dragon’s metabolic functions, such as digestion, depend on the correct temperature in its habitat. The guide below will help you with important points regarding the temperature setup in your pet’s habitat and help you decide which thermometer is best for you.

Best Thermometer for Bearded Dragons

Thermometers are one of the key features to include in your bearded dragon’s habitat. It’s a simple, yet important device to have in your set-up. While it may seem hard to go wrong when choosing a thermometer, there are certain features you should definitely look out for to make sure you’re making the best choice. You’ll also want to have at least two to check on the hot and cool parts of your enclosure.


🏆 Our Overall #1 Top Pick

We recommend adding this temperature gun to your bearded dragon care kit along with an in-tank thermometer. The Etekcity Lasergrip IR Temp Gun is perfect for quick spot-checking in your beardie’s enclosure. Laster temperature guns like this one let you quickly check basking areas and cooler spots to make sure you’re providing the best environment possible.

If you’re serious about bearded dragon keeping, this tool is a must-have. We don’t love that it takes 9V batteries, but we’ve found the battery lasts a very long time and the auto-shutoff feature is handy. Do not point this laser in your eyes, someone else’s eyes, or your bearded dragon’s eyes.

How to Choose a Good Thermometer?

Durability

You will use your thermometer quite often so it’s good to invest in a good quality one that is durable. Especially for the thermometer near your basking spot which can take a lot of beating in the extreme temperatures. The durability of a thermometer will also ensure that it doesn’t break down unexpectedly, and possibly without you noticing it, which can lead to inaccurate temperature readings. These can lead to health problems for your beardie such as loss of appetite if the temperatures drop too much.

Accuracy

It goes without saying that you need accurate temperature readings to ensure that you are getting the correct temperature ranges for your dragon’s habitat. This is a non-negotiable since your bearded dragon’s health depends on it! It’s good practice to always keep an extra thermometer handy to check the accuracy of the ones in your enclosure.

Power Source

Most digital thermometers will need batteries to run so you should factor these in when you choose. It’s good to invest in rechargeable batteries so you can cut down on waste and running costs using disposable batteries. However, there are also some thermometers that you can plug in so you won’t have to worry about changing (or forgetting to) the batteries.

Method of reading the temperature

Thermometers can read the temperature of an object directly using a probe by measuring the resistivity of the object. This is quite accurate but will measure the temperature of an object directly so it may not accurately represent the ambient (or air) temperatures in your tank. 

Another method is via infrared (IR) light which is the most advanced and quickest way to get a reading. These are found in temperature guns and are quite useful and handy since you can just point at anything and read the temperature accurately. 

Lastly, some thermometers take the ambient temperature of an area. These usually take some time to stabilize and read the temperature of an area accurately.

Usually, you’ll want to know the exact temperature for your basking spot so probe type or IR temp guns are highly recommended thermometers. 

Unit of reading (Fahrenheit vs. Celsius)

Though most thermometers are able to switch between different temperature units, you should make sure that the one you’re getting displays the unit you are comfortable with. You don’t want to have to convert every time! You may also want to go for thermometers with a large display so that you don’t have to peer into your tank so much when reading the thermometer. 

Different Types of Thermometers

There are generally three types of thermometers to choose from, each differing mainly in the accuracy of a reading, how quick you can get a reading, or how to take a reading. Thermometers with built in hygrometers are also available.

Digital Thermometer

Digital thermometers are battery operated thermometers that usually come with a probe that uses a resistor. They display the temperature reading on a small digital LCD screen and are usually quite accurate. The probe type digital thermometers are great for taking the temperatures of exact spots like the hot or cool zones of your tank.

Analog Thermometer

Analog thermometers do not require batteries and have a dial against a printed temperature scale to show the temperature reading. They work by using differential thermal expansion of a bimetallic strip. 

Chemical Thermometer

Chemical thermometers usually use mercury or another thermosensitive substance in a thin glass bulb and strip. Changes in temperature cause the chemical substance to expand or contract moving up or down the strip. The temperature is read against a graduated scale or background (calibrated with measurements like a ruler).

2-in-1 types (with built in hygrometer)

Some thermometers have a built in hygrometer or humidity gauge to read the humidity levels in your enclosure. These are also great since you can just have one device to read both temp and humidity levels in your tank. For these, make sure you are getting a good kind as well since you need to make sure both readings are accurate. 

#1: Etekcity Lasergrip IR Temp Gun

What’s The Best Temperature For My Bearded Dragon Enclosure?

Proper Temperatures for a Baby Bearded Dragon

The basking spot temperature should be 100-110 °F for babies (0-2 months) with the cooler part of the tank ranging from 80-90°F. The heat helps with your dragon’s digestion which helps them grow well.

Proper Temperatures for a Juvenile Bearded Dragon

At the early part of the juvenile stage (2-6 months) of a bearded dragon, about 2-3 months, they can maintain warmer temperatures at about 98-100°F to aid with their growth. Juveniles will do fine with slightly cooler temperatures in the 95-100°F range for their basking spot and 75-80°F for the cool side.

Proper Temperatures for an Adult Bearded Dragon

Adult bearded dragons (8 months onwards) can tolerate cooler temperatures so their basking spot can be 95-100°F with the cooler part of the tank at 75-80°F.

Nighttime Temperatures

Nighttime temperature in your terrarium should be between 70-75°F. However, you may have to adjust this depending on your tank’s size or the ambient temperature at your home. If the weather is a bit cooler, then you should consider using a heating pad or a ceramic heating element to maintain the temperature at night.

Where to Place the Thermometer in a Bearded Dragon Enclosure

You will need two thermometers one on the highest perch of your basking spot (nearest to your bearded dragon basking lamp) and another at the cooler side of your tank on the other end. It’s also good to have another back-up thermometer or a temperature gun which will be quite useful for spot checks.

You should also watch for excess humidity or stale air in your enclosure which can lead to inaccurate temperature readings. Avoid this by making sure your tank has good ventilation using a screen cover and placing it in an area with good airflow.

FAQs

What Temperature Should a Bearded Dragon’s Tank Be?

The temperature in a bearded dragon’s tank should range from 75-80°F in the cooler part and 95-100°F in the hotter part near the basking spot during the day.

At night, the temperature should be between 70-75°F. If the ambient levels fall below 65°F at night, consider using a heating pad or a ceramic heating element to heat up the tank at night. Take note that babies and juveniles will need slightly higher temperatures in their basking spot during the day to aid with their digestion and hence, growth.

Where Should I Put The Thermometer In My Bearded Dragon Tank?

Put one thermometer on each end of your tank to monitor the hot and cool part of the tank. Put the thermometer on the hot part near the highest perch of your basking spot right below the heating lamp where your bearded dragon basks.

It’s important to keep a good temperature range in your tank to help your beardie regulate its body temperature as it pleases. Providing a few hiding spots and several levels near the basking lamp will help as well.

How Long Can Bearded Dragons Go Without Heat?

As long as the temperatures do not fall below 65°F, bearded dragons can survive without heat for 24 hours (1 day). After that, the lack of heat will start to have consequences on their health since they will not be able to digest their food properly. It can also lead to lethargy and a loss of appetite. They may start to go into brumation as well which is not good if they are babies or juveniles since this will affect their growth.

Pro-tip

Keep a spare heat lamp or basking lamp in the event that the one in your tank breaks. If you don’t have one, keep a covered heat pad near your beardie or run to the nearest hardware store and purchase a 65W flood lamp to use temporarily.

Can Bearded Dragons Die From Too Much Heat?

Yes, bearded dragons can suffer from too much heat. They can die from a stroke or overheating. Pay closer attention to your tank’s temperature especially when you have a smaller tank that may not retain a big enough temperature range from hot to cold. If you notice your bearded dragon digging or trying to escape the tank, then it may be too hot.

Pay attention to the temperature on your basking spot as well (the surface your dragon perches on to bask) – the temperature of the rock or driftwood should not exceed 120°F because this can easily scald their tummies. The skin on their bellies is quite thin and a temperature of 122°F and above can lead to cell injury or death.

Conclusion

If you have the budget for it, go for a handheld temperature gun in addition to a digital probe-type thermometer for your basking spot and an ambient temperature reader in your cool spot. This allows you to monitor any spot of your tank with the temp gun but also quickly check the hot and cool side at a glance. However, a lot of budget friendly options also exist with several digital thermometers (both probe and ambient type) available in the market. 

Though a thermometer may be a simple gadget for your bearded dragon set-up, your dragon’s health and well-being relies a lot on it. Small changes in your temperature can lead to loss of appetite and indigestion so make sure you are able to monitor your temperatures well with a good quality and accurate thermometer.
