As a pet lover, you want your bearded dragon to be happy and healthy. One of the best ways for this is by monitoring its environment. This also includes maintaining its proper humidity levels.

Bearded dragons are susceptible to respiratory infections if their humidity isn’t properly monitored. Hygrometers are the best way to monitor humidity levels in your beardie’s habitat.

If you own a bearded dragon and want to monitor his humidity but don’t know which hygrometer is the best for him, we have good news. We have spent a lot of time researching the best-bearded dragon hygrometers available in the market. And we have finalized the top 5 best hygrometers for reptiles.

This article will discuss different kinds of hygrometers for bearded dragons and information on which one to buy.

Before discussing the top 5 hygrometers, let’s first explore what hygrometers are. It’ll help you in choosing the best hygrometer for your little champion.

What is a Hygrometer?

A hygrometer is a device used to measure humidity. It can be as simple as a wet and dry bulb thermometer or as complex as a digital laser sensor. Hygrometers can be analog or digital, but both are equally effective when measuring humidity for bearded dragons.

Types of Hygrometers

There are three different types of hygrometers, each with its distinctive methods of measuring humidity.

  1. The first is the mechanical hygrometer, which relies on natural properties in organic materials to measure humidity levels.
  2. The second type of hygrometer is electrical, which generally uses resistance or capacitance to determine humidity levels.
  3. Finally, the most precise hygrometers are dew point hygrometers, which detect even the smallest amount of moisture in the air.

Here Are Our Top 5 Best Hygrometers for Bearded Dragons

Bearded dragons like a relative humidity of 50-60% in their home cage. Most people build their beardie homes simultaneously in captivity since it looks reasonable compared to what nature provides. However, maintaining a bearded dragon environment below 50 percent humidity causes several health difficulties, including respiratory illnesses that lead to mortality.

So, what controls most bearded dragons’ temperature? Moving or not moving, actively absorbing or shedding heat via evaporation from different body regions are all engaged in thermoregulation. Moving, for example, may effectively increase or drop your body temperature depending on your orientation.

The best approach for a beardie to control its body temperature is to move away from the sun and absorb or lose heat via its skin and lungs (evaporation). The rationale is simple: changing beardie behavior needs energy (in food) and time (in hours each day). That implies avoiding extremes in temperature is the best method.

Finally, we can explain how the Bearded Dragon’s hygrometer works: a cold mirror! Frank Mossman invented this technique for people to monitor humidity in 1972, but it has only been regularly utilized on telescopes since then. The concept is simple: as light enters a slowing medium (like glass), part of it reflects off the interface. In this scenario, distilled water on top of a mirror reflects around 4% of any incoming light. Because lizards absorb energy from light reflected them, the mirror is both an accurate assessment of ambient humidity and a convenient tool for keeping your pet happy.

Consider how a beardie can keep its body temperature in the 80s while the air around it stays at an average temperature. This is because they have a malfunctioning hygrometer in their skull.

Benefits of Using Best Hygrometers for Bearded Dragons

Humidity plays a pivotal role in the overall health of every bearded dragon. There are many different ways to measure the level of humidity in a vivarium. The best way is using hygrometers. It has many benefits, including:

  • It’s easy to mount it or place it inside the vivarium
  • You can check the humidity level anytime you want
  • It has an accurate reading and also comes with a temperature reading
  • Hygrometers are widely available, and they can be bought both online and in pet stores
  • There is a wide variety of them to choose from

How to Choose the Best Hygrometer for Bearded Dragons?

Let’s have a look at the critical factors you should consider while buying the best hygrometers for bearded dragons:

Accuracy

High-quality hygrometers must be accurate to measure humidity correctly. It’s not advisable to use low-cost models for keeping track of humidity levels because they aren’t reliable enough. The accuracy is measured in percentage points; the greater the number, the better.

Replaceable batteries

It’s not advisable to use low-cost devices because they don’t work for long, and you’ll have to replace them regularly. Thus, go for one with an inbuilt battery that allows you only to replace the battery when it dies out instead of purchasing a new device each time.

Price

When purchasing a hygrometer for a reptile tank, you should consider how much you’re willing to spend on it because many models have different budgets. Of course, you should buy a quality item, but it doesn’t have to be expensive.

Responsiveness

Go through its controls and check whether they are easy to use. Read reviews from other users or ask for advice in forums before making a purchase.

Hygrometers are handy devices for all pet owners who want to keep track of humidity levels in their bearded dragon’s habitat. Make the best choice by checking out our list of features above and choosing according to your needs!

FAQs

Where should I put the hygrometer?

To ensure that a bearded dragon can thrive, temperature variation in their home needs to be around 20°C from end to end, with a basking spot of 29°C.

A hygrometer will accurately measure ambient humidity in the home. You can place it anywhere in the tank, but a few factors to keep in mind. First, it should ideally be placed in the center of the rear wall, which is where your basking light is most likely to be. Second, you can place a heat mat or heat tape in that corner if you use a heat mat or heat tape.

If the terrarium does not have a back wall, try to place it in the middle of the largest sidewall, away from any objects that might obstruct readings. Remember to keep it at least 5 cm away from anything that will obstruct the view of the dial (e.g., substrate, decorations, etc.).

If you use a probe to measure humidity in the terrarium, placing it in the tank will influence the humidity reading. Remember that heat rises and cold sinks, so it will measure the humidity in a different part of the tank depending on where the probe is located.

Just because some pet owners cannot place the hygrometers at these recommended places, that’s why they sometimes get faulty readings.

What is bearded dragon thermoregulation, and why do you need it?

To mimic their natural environment, provide a heating source (light bulb) and a basking place (heat mat or heat lamp under the tank). This way, your bearded dragon can benefit from both heating and light sources and thermoregulate properly. It will also synthesize vitamin D3 if the UVB lights are on for 8 hours per day.

Why bearded dragon humidity 60?

Bearded dragons like dry, arid environments and do not need high humidity. High humidity can cause impaction (digestive system blockage) and lead to serious health problems.

What should the humidity be for a bearded dragon at night?

Recommended humidity for bearded dragons at night is around 20%.

Does bearded dragon-like soaking in the water?

Yes, it does! It helps dragons to get rid of waste (urates and feces) if they do not like to use their dish for this purpose.

How is it possible to have bearded dragon humidity 70 at night?

To have 70% humidity at night, you need to run a very wet substrate (soil or sand) and a nearby humidifier.

Why is bearded dragon humidity too high, not favorable?

Having too high humidity can lead to serious health problems for your bearded dragon, such as impaction. It can also lead to respiratory issues.

What do you need to know when you want to order a thermometer for a bearded dragon?

Make sure that the thermometer is not too long since it can burn your dragon’s tummy. Also, make sure you get both temperatures (digital and non-digital).

Where to buy your bearded dragon thermometer?

You can purchase it from Amazon, which offers a variety of options. You can also order it from your local pet store or reptile supplier.
