A hygrometer is a humidity sensor or air moisture sensor and is a great addition to any home or garden.
Our ClimeMET Hygrometer Dial can be used as an indoor hygrometer for keeping your home at a safe humidity level to avoid mold and damp,. It can also be used in the garden or greenhouse as an outdoor hygrometer to help you keep an eye on humidity levels for your plants.
The 4303 is self-contained and continually measures surrounding air conditions without the need for external wires or sensors. Humidity is displayed on a clear expanded scale carefully set in a large 9-inch weather-proof casing.
If you would like your weather dial engraved, please select personalisation when adding this item to your shopping basket, and enter the required text (up to 25 characters). Engraved items are suitable for indoor use only.
