Product information

Description

The TFA 30.5045.54 digital thermo-hygrometer is a compact indoor instrument for monitoring room temperature and relative humidity. It measures temperatures from 0 to 60 °C and displays values on a built-in screen with selectable °C/°F units. The device shows trend indications for temperature and humidity, stores maximum and minimum readings with manual or automatic reset, and is powered by a single 1.5 V AAA battery. Colored comfort-level zones on the display indicate whether the air is within a recommended range, too dry, or too humid, helping you maintain a healthy indoor climate for people, plants and furnishings.

Advantages

This thermo-hygrometer provides clear, easy-to-read measurements on a backlit display, making it usable in low-light conditions. Trend arrows and stored max/min values allow quick review of recent climate changes, while the selectable measurement units and calibration option increase versatility and accuracy. Lightweight and compact, the device can also act as a wireless transmitter in compatible TFA weather station systems.

Suitable for

Home rooms (living room, bedroom, nursery)

Rooms with wooden furniture, floors or musical instruments
Additional transmitter for compatible TFA wireless weather stations

How to use

Place the thermo-hygrometer on a stable surface or mount it where it will measure representative indoor air (avoid direct sunlight, heating sources or draughts). Insert a 1.5 V AAA battery and select the preferred temperature unit (°C or °F). Read current temperature and relative humidity on the display; use trend arrows and stored max/min values to assess recent changes. Use the backlight for improved visibility in the dark and perform calibration if required to match a reference instrument.

Usage recommendations

For reliable readings, position the device away from direct heat sources and windows. Use the coloured comfort-level zones to guide ventilation and humidification/dehumidification actions: ventilate to reduce humidity or operate a humidifier to increase low humidity. Replace the AAA battery as soon as display dimming or irregular readings occur. When integrating with a compatible TFA wireless weather station, follow the station’s pairing instructions to use the thermo-hygrometer as an additional transmitter.
