Accurate weather station with inverse colour VA display and aesthetic design, with time and date controlled by DCF-77 radio signal (UK offset -1 hour), alarm clock, measures indoor temperature, humidity, barometric pressure and includes a wireless sensor for measuring outdoor temperature and humidity.

The measuring sensor is the Swiss brand SENSIRION which is used to achieve high accuracy of temperature and relative humidity measurements.

Key features:

• 6 animated weather forecast icons
• Inverse V. A. colour display
• Bar graph for trend or pressure, temperature or humidity
• Time and date are automatically controlled by the DCF-77 signal with UK -1 hour offset
• Supports up to 3 wireless sensors (1 supplied)
