## Long description

Compact digital indoor environment thermometer tfa dostmann 30.2025 measures ambient temperature in °C and °F and is designed for small spaces at home, office, car or caravan. The unit is powered by a single LR44 1.5 V battery and offers a clear digital readout in a slim housing measuring approximately 65 × 33 × 20 mm with a removable black frame and a slightly smaller white insert. A stainless-steel sensor probe on a 300 cm silicone cable allows the sensor to be routed to a different location for remote measurement.
Advantages
The thermometer provides straightforward numerical temperature display in both Celsius and Fahrenheit, suitable for quick ambient checks. Its compact dimensions and thin mounting depth make it suitable for installation in confined spaces or flush mounting behind the included frame. The stainless-steel probe with a long silicone cable enables measurement at a remote point while the main unit remains protected indoors. Battery operation with a single LR44 cell ensures simple, low-maintenance power supply.

How to use

Insert a single LR44 battery into the battery compartment following polarity markings, then replace the cover. The digital display will show the current temperature; select or interpret the reading in °C or °F as provided by the device.
Usage recommendations
Place the main unit in a dry, sheltered location away from direct heat sources or sunlight for reliable indoor readings. Ensure the stainless-steel probe is not in direct contact with water; use the probe outdoors only where brief exposure to moisture is acceptable and avoid submersion. Replace the LR44 battery when the display becomes dim or unstable.
