## Long description

The mechanical environment thermometer TFA-Dostmann 12.2057 is an analog outdoor thermometer designed to show ambient temperature in °C on a 13.8 cm diameter dial. The instrument requires no external power supply for temperature measurement and uses a mechanically filled capillary with coloured thermometer fluid; mercury is not used. The housing is lacquered metal with high-grade acrylic glass for the dial, finished in silver. The unit is built for outdoor placement in gardens, patios, balconies and other external utility areas where a simple, durable temperature display is required.
Advantages
This outdoor thermometer provides a clear, large-scale analog display that is easy to read from a distance. Its mechanical sensing eliminates the need for batteries for temperature measurement, while weather-resistant materials—lacquered metal and acrylic glass—offer durability throughout seasonal changes. A solar-powered light activates automatically at dusk to illuminate the scale for nighttime readability, and the product is designed for straightforward ground insertion.
Suitable for
Garden beds and borders
Patios and terraces
Balconies and small outdoor spaces
Utility areas such as sheds and greenhouses

How to use
Insert the provided spike into firm ground at the chosen outdoor location so the dial is easily visible. Ensure the solar cells receive daylight to charge during the day so the integrated illumination will operate automatically after dark. Read the ambient temperature on the analog dial in degrees Celsius; no batteries or external power are required for temperature sensing. Clean the acrylic glass and metal housing with a soft, damp cloth to remove dirt and debris as needed.
Usage recommendations
Position the thermometer in an open area away from direct heat sources (radiators, grills or reflective surfaces) to obtain accurate ambient readings. During severe winter conditions, check that the spike remains firmly anchored and remove heavy snow buildup from the dial to maintain visibility and function.
