Dryzone Digital Hygrometer - White - 6-Pack

The display will typically become faint or erratic. You may also notice consistently inaccurate readings. Replace with a CR2032 battery.

No, the Dryzone Hygrometer is designed for indoor use only and is not weatherproof.

For optimal use, check the readings daily or whenever you suspect a change in air quality, especially in areas prone to dampness.

The emoticons indicate humidity levels: a neutral face generally means ideal conditions, a slightly frowning face suggests high humidity (potential for condensation/mould), and a face with closed eyes suggests low humidity.

The temperature readings are accurate to within ±1 °C.

Yes, each hygrometer comes with a pre-installed CR2032 battery and an activation tab.

This device is not user-calibratable. It is designed to provide reliable readings out of the box within its specified accuracy range.

Ensure the plastic activation tab has been fully removed. If removed, try replacing the battery with a new CR2032.

Ensure the device is placed away from direct heat sources, drafts, or high humidity areas that could skew readings. Allow the device a few hours to acclimatize to a new environment. Check if the battery is low.

The emoticon changes based on pre-set humidity thresholds. Allow sufficient time for the environment's humidity to change significantly. Ensure the device is functioning and displaying temperature/humidity values.
