Thermo-Hygrometer TFA-Dostmann WS 5031
The Thermo-Hygrometer TFA-Dostmann WS 5031 is a compact digital device for monitoring indoor climate parameters. The unit displays temperature, relative humidity and time on a clear digital screen in a rectangular housing. Powered by a single AAA (1.5 V) battery, the instrument is designed for simple placement on shelves, desks or bedside tables to provide continuous readout of current indoor conditions and help maintain comfortable and healthy spaces.
The instrument combines temperature and humidity measurement with a built-in clock in a slim, rectangular case that fits small spaces. Its digital display delivers easy-to-read values and quick recognition of indoor climate changes. Low power consumption ensures extended battery life for uninterrupted monitoring. The compact dimensions allow versatile placement in living rooms, offices and bedrooms while the simple operation requires no technical setup.
Install a single AAA 1.5 V battery in the battery compartment, place the thermo-hygrometer on a stable, level surface away from direct sunlight, heating sources and drafts to ensure accurate readings. Allow the sensor a few minutes to stabilise after placement or after battery replacement. Read current temperature, relative humidity and time directly from the digital display. For relocations, wait a short period for the device to adapt to the new environment before taking readings.
For best measurement accuracy, position the device at breathing height in frequently used rooms and avoid placing it close to windows, radiators or kitchens. Replace the battery when display dimming or irregular readings appear, and periodically clean the housing with a dry cloth. Use the device as part of routine indoor climate checks to support comfort, plant care and safe storage of sensitive items.
