## Long description

The TFA-Dostmann Zeno Black indoor/outdoor thermometer provides clear time, temperature and weather information on a large digital display. A radio-controlled clock ensures accurate timekeeping and offers alarm with snooze. The unit measures indoor temperature and receives outdoor temperature via the included wireless transmitter; up to two additional temperature transmitters can be added. A barometer indicates air pressure changes and gives a short-term weather forecast using trend arrows and symbols. The device can be placed on a table or mounted on a wall and is powered by AA/AAA batteries.
Advantages

The large, easy-to-read display shows current, minimum and maximum temperatures simultaneously, while the external wireless transmitter communicates outdoor data up to 100 m line-of-sight. Expandability to additional transmitters allows monitoring of multiple locations such as basement or garage. The device supports both tabletop placement and wall mounting for flexible installation.
