5 Best Reptile Hygrometer Picks | Reptile Humidity And Temp Gauge

What is the best hygrometer?


While diminished humidity during winter can be an inconvenience for us, it can be fatal for reptiles.


In this article, we’ll take a look at the best reptile hygrometers for maintaining humidity levels. We tried to vary our picks as much as possible to suit different needs. Let’s see!

Best Hygrometer

Hygrometers are necessary for a range of reptiles:

  • skinks and lizards (the pic above is from a local zoo)
  • Geckos and snakes
  • turtles and tortoises


You may also need them for keeping different types of amphibians like frogs and salamanders as well.


Being cold-blooded, reptiles, amphibians, and other ectotherms can’t hold their body’s temperature at a certain level. Instead, they depend on the surrounding environment. That’s why giving them the right setup is crucial.


Here’s a round-up of our top picks for the best digital thermometer hygrometer, with much more info below.

You may decide to get a hygrometer in addition to a reptile thermostat, and you will also need heat lamps and a turtle tank water heater. However, here is some more info on picking the right reptile humidity gauge for your set-up.


Analog Vs Digital


Recently, most terrarium owners have been opting for digital hygrometers for their easier setup and lower price. They tend to maintain accurate calibration over a long period of time, which is ideal for beginners. On the negative side, dependence on batteries opens the way for occasional inaccuracies.


That’s where the analog devices shine. They pick up the humidity directly without power. But they still need frequent calibration to ensure accuracy.


Recently, brands have been equipping their digital hygrometers with built-in memories. This way, they can record the maximum and minimum humidity to know if they stray off when you’re not there. Clearly, this feature can never be seen in an analog device.


Wireless Vs Wired


If you decide on a digital hygrometer, you’ll be left to choose from 2 operation methods: wireless and wired.


Wireless hygrometers suit minimal setups. All you have to do is stick the device on the wall. But as you might imagine, this may not be that accurate. It won’t be enough if you want to pinpoint your testing area.


Wired devices can readily provide this. You can fix their probes in whatever place you want. Some models equip these probes with a waterproof build, which makes them much more versatile.


Best Reptile Hygrometer Review


In each of the following reviews, I’ll dive deeper into each product to find out about the accuracy, suitable setup, range, etc. I’ll also highlight any downside that can impact your experience.



Quntis Hygrometer And Thermometer – Best Wireless

How about a hygrometer that works for you and your reptile at the same time? If you think that suits your needs, you can’t find anything better than Quntis.


If you order this hygrometer, you’ll receive two devices. The first one features a large blue display that shows the clock, temperature, humidity, and weather forecast. The second device is a small solid remote that has nothing but a sensor. Obviously, the remote should be placed inside your reptile enclosure, while the screen remains outside.


On the screen, you’ll find 2 humidity readings. The “inside” reading denotes the humidity at the screen’s position. While the “outside” reading relates to your reptile’s tank. Reading these values couldn’t be easier thanks to the convenient blue backlight.


Since the remote was originally built to be placed outdoors, it features an IP44 waterproof construction.


The only thing I don’t like about it is the large sensor size. Leaving it exposed can invite your reptiles to shred it into pieces. That’s why I’d only recommend it for fairly peaceful species.



  • Humidity range: 20% to 95%
  • Temperature range: 14 to 122 °F (main unit), -13 to 122 °F (remote sensor)



  • Built-in alarm function
  • Features a convenient blue screen backlight
  • High accuracy


  • The internal sensor is too large


Jlenoveg Thermometer Humidity Gauge – Smallest

Got a feisty reptile? The Jlenoveg thermo-hygrometer should be your best bet in that case. Unlike the previous product, this device has the screen and the sensor in one compact gadget.


When it comes to mounting, Jlenoveg gives you two options. First, you can use the adhesive pad placed on the front of the device to mount it on your tank’s wall. Second, you can use the built-in hook to hang it over the tank’s edge.


Luckily, both ways are sturdy enough. The sticky pad, in particular, seems to be the favorite of many. An Amazon customer says that it can support the full weight of his young ball python!


Generally, most users are happy with the quality and clarity of the screen. However, I wish Jlenoveg had placed a backlight to make it easier to read the values in poor lighting conditions. This can’t be viewed as a major flaw, though.



  • Humidity range: 20% to 90%
  • Temperature range: 14 to 122 °F



  • Small, convenient construction
  • Easy mounting
  • The sticky pad can support heavy loads


  • The screen would’ve been clearer with a backlight


Zoo Med Reptile Thermometer – Best Wired

I can’t say how much I love Zoo Med products. Being primarily specialized in reptiles, they produce basking lamps, UV lights, gauges, and pretty much everything you’ll need for your terrarium.


Their humidity gauge comes as a small device with a digital display. Unlike the two previous models, this device picks up the temperature and humidity via 2 separate wired sensors.


The temperature sensor comes as a steel probe that can be submerged underwater or pushed under the substrate. The humidity probe, on the other hand, features small openings from which the air can be analyzed. Naturally, such a design isn’t waterproof by any means.


To facilitate the setup, Zoo Med ships two suction cups that can hold the two probes in place. The device itself has a small recess to hang it next to your turtle tank (or whatever pet you have), probably over a screw or another suction cup.



  • Humidity range: N/A
  • Temperature range: -10 to 122 °F



  • Easy mounting with the shipped suction cups
  • High accuracy
  • Waterproof temperature probe


  • The screen would’ve been clearer with a backlight


Exo Terra Digital Reptile Hygrometer

Until now, all the hygrometers featured on this list detects the temperature as a side benefit. While this can be convenient, it’ll also make the device unnecessarily large for folks who already own a thermometer. If this applies to you, consider this hygrometer from Exo Terra.


The readout unit measures 1” by 5” by 8”. It shows nothing but the RH percentage. It can be mounted with the shipped hook & loop fastener. And if you own a tank made by Exo Terra, you can also slide the hygrometer in the dedicated recess.


The reading is picked with a wired probe that goes into the terrarium. The shipment includes a small suction cup that holds the wire to the terrarium’s wall.


This hygrometer records the minimum and maximum humidity values via its built-in memory. You can easily flip through these values by the small button placed at the front.



  • Compact construction
  • Simple value readout
  • Fits perfectly to Exo Terra tanks


  • Quite pricey, especially as it doesn’t measure temperature


Reptile Thermometer


Choosing the best hygrometer depends majorly on your setup and needs. The Quntis Digital Hygrometer would be ideal if you want to measure your home and terrarium humidity at the same time.


Interested in a more compact device? Jlenoveg Reptile Thermo-Hygrometer will probably suit you. I like that it can easily attach to the terrarium’s wall via its sticky pad.


Lastly, if you want to opt for the good old wires, consider the Zoo Med Digital Humidity Gauge. It comes with small suction cups to instantly fix the wires where you want.
