Zoo Med Dual Thermometer/Humidity Gauge
One dial shows both temperature and humidity, so you can check your terrarium at a glance. The Zoo Med Dual Thermometer/Humidity Gauge combines a temperature dial and a humidity dial in a single analog unit, known on Zoo Med's own site as the Precision Analog Thermometer & Humidity Gauge, giving keepers an at-a-glance read on two of the most important numbers in any reptile enclosure.
Key features
- Two readings, one gauge – temperature and humidity combined in a single analog dial.
- Wide range – reads temperature from -6°C to 49°C and humidity from 0% to 100%.
- No batteries – analog dial, nothing to charge or replace.
- Backed by a Zoo Med warranty – 6 months from Zoo Med.

Suitable for, and not suitable for
Suitable for monitoring air temperature and humidity in reptile and amphibian terrariums. Zoo Med doesn't publish a stated accuracy tolerance for this dial, so treat it as a general guide alongside a separate digital probe thermometer if you need precise readings for a temperature-sensitive species.
Care and maintenance
Zoo Med doesn't publish specific calibration steps for this gauge. If a reading looks consistently off against a known-accurate thermometer, replace the unit rather than attempting a field calibration.
Warranty and delivery
Zoo Med backs this gauge with a 6-month warranty, in addition to the consumer guarantees that apply automatically under Australian Consumer Law. Standard parcel delivery Australia-wide.
Common questions
Does this need batteries?
No. It's a fully analog dial gauge – there's nothing to charge or replace.
How accurate is it?
Zoo Med doesn't publish an accuracy figure for this gauge. For species with a narrow temperature tolerance, we'd suggest pairing it with a digital probe thermometer for a precise check.
Where should I mount it?
Zoo Med doesn't specify a mounting method for this model. Position it away from direct heat sources such as basking bulbs so it reads ambient conditions rather than the heat source itself.
What's the difference between this and Zoo Med's other dual gauges?
Zoo Med also sells a hook-and-loop mounted dual gauge with a different temperature range. Check your model's range against your enclosure's needs before buying spares.
