Analog Hygrometer

  • For monitoring terrarium humidity levels
  • Easy-to-read display
  • Easy to install

The Exo Terra® Analog Hygrometer allows you to carefully monitor the humidity level in your terrarium. Correct humidity levels are essential for the overall health of reptiles and amphibians. Incorrect humidity levels may lead to electrolyte imbalance, dehydration, dysecdysis (improper shedding), hyperkeratosis (thickening of the horny layers of the skin), respiratory infections, etc… Humidity requirements vary greatly depending on the species and their natural environmental conditions. Carefully research the specific humidity needs of your reptile or amphibian species.

1. Remove paper backing.
2. Ensure surface is clean and dry.
3. Press thermometer firmly onto surface


Reptiles are ectotherm, and use heat from an external source to thermoregulate their optimal body temperature. Providing the correct species related temperature gradient and humidity levels in the terrarium is an important factor for the long term husbandry of reptiles and amphibians. With the Exo Terra® Monitoring Devices you can monitor the temperature and humidity levels in your terrarium 24/7, to make sure that the values are similar to those found in a desert or tropical environment. Keeping a keen eye on the temperature and humidity levels with the Exo Terra® Monitoring Devices will also help you to prevent overheating and undercooling during hot summer days or cold winter nights. 


Every reptile-, amphibian- or insect species thrives only in its own specific climatic environment. Often these species live in a microclimate, where the climatic conditions differ greatly from the macroclimatic conditions of a particular region. Thoroughly research the preferred optimum temperature (POTR) and humidity range for your specific animal, so you can create the correct temperature gradients and humidity inside the terrarium for your animals. The Exo Terra® Monitoring Devices can assist you in creating the right climatic conditions and allow you to monitor these values 24/7 to make sure your animals are kept under optimal conditions.


Exo Terra® Monitoring Devices are very accurate devices that allow you to monitor temperature and humidity levels inside your terrarium. The Exo Terra® Monitoring Devices are easy to install and the displays easy to read, facilitating the monitoring. Exo Terra® offer various types of Monitoring Devices, from simple analog Thermometers and Hygrometers, to Digital Thermometers and Hygrometers with remote sensor and min/max memory. Exo Terra® even offers pocket sized, “point-and-click” thermometer to instantly determine the temperatures of basking sites, hiding caves, incubation media, hibernation temperatures, your reptile’s body temperature, or to measure temperatures “on-the-spot” during field trips.
