Product information

Description

The TFA-Dostmann 35.1142 Black LCD is a battery-powered indoor/outdoor thermometer and hygrometer that monitors temperature and humidity at up to four measuring points simultaneously. The compact device shows time, date and day of week via radio signal, stores maximum and minimum values and indicates trends for measured parameters. An integrated electronic barometer displays local air pressure and provides a simple weather forecast symbol based on pressure changes.

Advantages

This black LCD unit measures temperature and humidity for the main location plus three additional wireless sensors or outdoor readings, helping to compare climate conditions across rooms or between indoors and outdoors. Trend arrows and stored max/min values make it easy to observe changes over time. The built-in barometer and weather symbol offer a quick forecast, while radio-controlled time and alarm increase convenience. Compact dimensions and battery operation allow flexible placement.

Suitable for

Monitoring indoor climate in living room, bedroom or children's room
Comparing conditions between basement, conservatory and main rooms
Keeping track of outdoor temperature and humidity near the house
