Product information

Description

The Indoor Outdoor Hygrometer GARNI GARNI439 Line Black AC Thermometer is a compact weather-monitoring device designed for household use. It measures both indoor and outdoor temperature and humidity, displays current readings on a built-in display and shows temperature trends. The unit is powered primarily by AC with a 3V battery backup and communicates at a transmission frequency of 433.92 GHz for the outdoor sensor signal. Its compact dimensions and black finish make it suitable for placement on a table, shelf or wall-mounted position.

Advantages

The device provides simultaneous indoor and outdoor measurements with clearly visible readouts on the integrated display. Temperature trend indication helps monitor gradual changes, and the combined thermometer and hygrometer functions allow users to assess comfort and conditions quickly. The AC power supply with a 3V battery option ensures continuous operation in typical home environments, while the compact size and lightweight construction allow flexible placement. The transmission frequency used by the remote sensor supports reliable signal transfer within a normal household range.

How to use

Place the main unit indoors on a stable surface or mount it on a wall where the display is easily visible. Install the outdoor sensor in a sheltered outdoor location away from direct sun and precipitation but exposed to ambient air for accurate readings. Connect the main unit to AC power and insert a 3V battery if required for backup operation. Allow several minutes for the outdoor sensor signal to synchronize with the base unit; the display will show both indoor and outdoor temperature and humidity along with the temperature trend. Adjust placement of the sensor or main unit as needed to obtain stable signal reception and accurate environmental readings.

Usage recommendations

To ensure accurate measurements and reliable wireless transmission, avoid placing the outdoor sensor near heat sources, direct sunlight or heavy metallic obstructions. Regularly check battery status if using the 3V backup and perform periodic cleaning of the sensor housing to prevent dust accumulation that could affect humidity readings.
