ReptiZoo Infrared Thermometer SH138 | Reptile Vivarium Thermometer

The RZ Infrared Thermometer SH138 is a handheld non-contact thermometer designed for reptile keepers who need accurate surface temperature readings without disturbing their animals or opening the enclosure. Point, shoot, read — it is that straightforward, and for keepers managing heat-sensitive species or glass-fronted terrariums, that matters.

How It Works

The SH138 reads the surface temperature of objects within the enclosure from a safe distance, meaning you can check basking spots, cool zones, and substrate surfaces without introducing stress or heat loss by opening the vivarium. This is particularly useful for shy or defensive species where hands-in disturbance should be minimised.

Important: Surface Temperature, Not Ambient Air

This thermometer measures the temperature of surfaces — glass, slate, wood, substrate, hides — not the air temperature inside the enclosure. For ambient air readings, a separate probe or digital thermometer is required. Used correctly alongside an air thermometer, the SH138 gives you a more complete picture of your thermal gradient than either tool alone.

Designed for Terrarium Use

The handheld format makes it practical for daily checks across multiple enclosures, and its non-contact operation is well-suited to glass-fronted vivariums where inserting a probe repeatedly is impractical. Reptile keepers managing collections will find it saves time without compromising the accuracy of their monitoring routine.

A reliable surface thermometer is one of the most underused tools in reptile keeping — the RZ SH138 makes it easy to know exactly what temperature your animal is actually sitting on, not just what the air around it reads.
