Window Thermometer Keltin 205×17 mm, white — outdoor/indoor temperature gauge

The Keltin window thermometer 205×17 mm in white is a compact linear temperature gauge designed for mounting on window frames, glazed doors or nearby walls. Its narrow profile and clear scale provide a direct visual indication of ambient temperature for indoor and outdoor use where a simple, economical display is required. The device shows temperature via a sliding indicator along a printed scale, allowing quick assessment of conditions in homes, offices, balconies and small greenhouses.

Advantages

The thermometer’s slim 205×17 mm design saves space and fits neatly on most window profiles without obstructing views. A high-contrast scale and marker make reading easy from short distances, while the white finish integrates unobtrusively with typical window and wall surfaces. The product requires no power source or maintenance beyond occasional cleaning and provides an affordable, low-tech solution for continuous temperature monitoring.

How to use

Mount the Keltin window thermometer on a clean, dry section of a window frame, glazed door or interior wall using the recommended adhesive or mounting method. Position it so the scale is easily visible from the usual viewing angle. Allow the thermometer to equilibrate for several minutes so the sliding indicator stabilizes at the current ambient temperature. Read the temperature by noting the marker position against the printed scale. For more accurate comparison between indoor and outdoor conditions, place one unit inside and one in a sheltered outdoor spot at similar height.

Usage recommendations

To ensure consistent readings, avoid mounting the thermometer in direct sunlight, immediately above heat sources or near vents. For outdoor placement choose a sheltered, shaded location to reduce direct weather exposure. Clean the scale surface gently with a soft cloth when necessary and avoid abrasive cleaners that could damage the printed markings.
