Exo Terra Digital Thermometer - For Terrarium

The Exo Terra Digital Thermometer measures temperature inside the terrarium using a remote sensor, with a programmable minimum and maximum memory.

Why the Min/Max Memory Matters

A glance at the display tells you the temperature now. It cannot tell you what happened overnight, or during the hottest part of an afternoon while you were out.

That is when things go wrong. Enclosures overheat when afternoon sun reaches the room, or fall far colder overnight than the keeper realises, and an animal can spend hours a day outside its safe range while every spot-check looks perfectly fine. The min/max memory records the extremes, so you see the real daily swing.

This is not a minor detail. Reptiles held too cool stop digesting properly and can develop gut impaction with food still inside them; held too hot, they overheat quickly and have limited means of cooling down.

Why a Remote Sensor

It reads conditions where the animal actually is, rather than on the outside of the glass or up in the canopy. Two ends of the same terrarium can differ by 10°C or more — which is the point of a gradient — so where you put the sensor determines what the number means.

Key Features

• Accurate temperature indication
• Remote sensor held in place with a suction cup
• Programmable minimum/maximum temperature memory
• Single button operation
• Slides into an Exo Terra Compact Top, or mounts with the included hook and loop fastener

Getting Useful Readings

• Ideally run two — one at the warm end and one at the cool end — so you can see the gradient rather than a single point.
• Keep the sensor out of direct lamp light, which will read high.
• For basking surface temperature use an infrared thermometer instead. A basking rock can be far hotter than the air above it, and that gap is how reptiles get burned in enclosures the keeper believed were correct.
