Elektronische omgevingsthermometer TFA-Dostmann 30.5054.01 binnen digitaal zwart wit

The TFA-Dostmann 30.5054.01 Electronic environment thermometer is a compact indoor thermo-hygrometer with a high-contrast e-ink display that shows temperature and humidity clearly and glare-free. The device displays values in an easy-to-read black-on-white or inverted white-on-black layout, stores minimum and maximum readings, and includes a clock with date or weekday display. It is powered by a CR2032 battery and has a slim, portable design (75 × 13 × 75 mm).

Advantages

The e-ink display offers paper-like readability with high contrast and no glare; two display modes (black on white or inverted) increase legibility in different lighting. The thermo-hygrometer records minimum and maximum values for quick review and provides a comfort indicator (smiling face) when temperature and humidity are within optimal ranges. Multiple mounting options — fold-out stand, adhesive wall mount, nail hanging or rear magnet — allow flexible placement around the home. The device measures temperature in °C (also supports °F) within a practical indoor range and is lightweight for easy repositioning.

Suitable for

• Monitoring room climate in living rooms and bedrooms
• Checking humidity and temperature near plants or instrument storage
• Placement in nurseries and home offices for comfort control
• Use in kitchens or basements where compact, wall- or magnet-mounted sensing is useful
