Liquid environment thermometer tfa dostmann 14.6015 for outdoor use, °C, 235×103×26 mm, silver

Liquid environment thermometer tfa dostmann 14.6015 is an analogue outdoor thermometer with a Celsius scale designed for wall or window mounting. The compact housing (235×103×26 mm) and silver finish fit patios, balconies and garden walls. A sealed coloured liquid column gives a direct, battery-free reading of ambient air temperature. The instrument is manufactured in Germany and calibrated at two points to ensure reliable accuracy across its measurement range.

Advantages

The thermometer provides a clear analogue display that can be read from indoors when mounted on a window or attached to an external wall with the supplied stainless steel holder. Weatherproof construction and a durable plastic and stainless-steel combination resist outdoor conditions without electrical components. A coloured, non‑mercury liquid in the capillaries gives safe, visible temperature indication while the two-point calibration improves measurement precision.

Suitable for

• Monitoring outdoor ambient temperature from inside a home
• Mounting on window frames to read temperature without going outside
• Use on patios, balconies, garden walls or other exterior mounting locations
• Simple analogue temperature checks where no power source is available

How to use

Attach the stainless-steel holder to the outside of the window frame or to an exterior wall using appropriate screws. Position the thermometer so the dial is easily visible from the intended viewing location indoors or outside. Ensure the instrument is mounted vertically and avoid direct heat sources (sunlight striking the housing directly) to obtain representative ambient air readings. Read the temperature on the analogue liquid column; no setup or power is required.

Usage recommendations

For optimal accuracy, mount the thermometer in a shaded, ventilated location away from direct sunlight, radiators or other heat sources. Regularly check that the holder and screws remain secure; clean the housing with a soft cloth. The coloured liquid is non‑mercury and sealed, but damaged units should be replaced rather than repaired.
