Green Frog Thermometer Hygrometer

The metal frog frame thermometer hygrometer combines temperature and humidity measurement in a 9.8-inch decorative dial. It suits gardeners, greenhouse keepers and homeowners who want an attractive wall-mounted gauge for patio, garden or indoor spaces. The green frog design adds visual interest while providing practical climate monitoring for plants and comfort.

Temperature range -40 to 60 Celsius

The dial displays both Fahrenheit and Celsius across a -40°F to 140°F and -40°C to 60°C span, covering most outdoor and indoor conditions. Humidity reads from 0 to 100 percent, useful for greenhouse climate control and room comfort. Extreme environments beyond these limits will exceed the instrument's calibrated range.

Battery-free copper movement

The built-in copper plate movement operates without batteries, using automatic calibration after one to two hours of rest or manual gear adjustment for immediate readings. The metal frame and waterproof construction support permanent outdoor mounting on walls or fences. No power source or wiring is required for continuous operation.

Questions about this item

Will the 9.8-inch dial still be easy to read if I mount it on a shaded patio wall?

The dial shows both Fahrenheit and Celsius across a -40°F to 140°F range with large markings, so it remains legible in lower light conditions on a shaded wall.

How can I verify the hygrometer is giving accurate humidity readings after I hang it?

Let the unit sit for 1 to 2 hours so the internal copper plate movement can auto-calibrate, then check that the needle falls within the 0 to 100% scale for the current environment.

Does the package include mounting hardware, or do I need to buy screws separately?

The thermometer hygrometer arrives ready to hang with a built-in mounting point; only basic wall fixings such as a screw or nail suited to your surface are needed.
