## Summary description

The Technoline WL 1020 is a silver indoor thermometer and hygrometer powered by AC or AAA batteries. It measures air quality, humidity, and temperature, displaying trends for both humidity and temperature. Its compact size of 82mm x 25mm makes it suitable for various indoor environments.

## Long description

The Technoline WL 1020 Silver AC/Battery Indoor Thermometer Hygrometer is a compact indoor air quality monitor that measures temperature, humidity and volatile organic compounds (TVOC) to help assess room climate. It displays air quality with a five-star symbol system across 11 levels and shows ventilation recommendations with coloured background lighting. The device runs on AAA batteries or via the included USB adapter; to save battery power, air quality is displayed only while the USB adapter is connected.
Advantages
The built-in mixed-gas (VOC) sensor continuously monitors indoor pollutants and provides analysis and ventilation prompts based on measured values. Air quality is visualised through up to five star symbols and coloured backlighting (yellow = ventilation recommended, red = ventilation strongly recommended). The unit also shows time, temperature and relative humidity and indicates trends for temperature and humidity, while offering a clock and alarm functions. Its compact silver design and dual power options (AC via USB adapter or AAA batteries) make it suitable for various rooms.
Suitable for
Monitoring air quality in bedrooms and living rooms
Keeping track of humidity and temperature in home offices
Assessing indoor pollutant levels in apartments and small offices
Use where a compact, battery/USB powered indoor climate display is required
Key specifications
Model: Technoline WL 1020
Measurements: temperature, relative humidity, TVOC-based air quality indication (approximate CO2 estimation)
Temperature range (indoor): -9.9 to 50 °C
Display: built-in display with five-star air quality indicator across 11 levels and coloured background lighting
Power: AAA batteries or USB adapter (USB adapter included); air quality display shown while USB adapter is connected to save battery
Functions: clock, alarm, trend indicators for temperature and humidity
Colour: Silver
Dimensions (approx.): 82 mm x 25 mm
How to use
Place the WL 1020 on a flat surface in the room to be monitored, away from direct sunlight and heat sources for accurate readings. Power the device with AAA batteries or connect the included USB adapter to enable continuous air quality display; when running on batteries, the air quality indicator is deactivated to conserve power. Read the air quality level from the star symbols and follow the coloured backlight for ventilation guidance: yellow indicates ventilation is recommended, red indicates ventilation is strongly recommended. Use the display to view current temperature, humidity and trend indications, and set the clock and alarm as needed.
Usage recommendations
For best accuracy, position the device at breathing height in a representative location of the room and avoid placing it near windows, radiators or air vents. Interpret the CO2 approximation with caution — the CO2 value is inferred from VOC-related sensor data, not directly measured.
