How to use

Place the thermo-hygrometer in the room or area where you want to monitor conditions, avoiding direct sunlight, radiators or other localized heat sources that can skew readings. For wall mounting, use the integrated hanger slot; for tabletop use, position it on a flat surface at eye level for easy reading. Allow the device to stabilize for several minutes after placement to obtain accurate measurements. Check the display periodically to monitor changes in temperature and humidity.

Usage recommendations

For consistent results, position the device away from drafts, windows and doors. Perform measurements at a typical room height (about 1–1.5 m above the floor) and avoid placing the unit within three feet of heating or cooling vents. Replace batteries when display dims or updates become slow to maintain measurement reliability.
