ZWS400 All-in-One Compact Weather Sensor
ZWS400 (optional ZWS40G with GPS/4G)
The ZWS400 is a compact weather sensor that measures temperature, humidity, pressure, rainfall and compass heading without a wind channel, in a smaller Ø110 mm x 188 mm housing weighing 1.5 kg. It is available in the UK through MetSensor UK.
- ✓ Five measured parameters: temperature, humidity, pressure, rainfall, compass
- ✓ Smaller and lighter housing than wind-equipped ZWS models
- ✓ Piezoelectric rainfall sensing
- ✓ IP67 general, IP68 pressure rating
- ✓ 6-8 year design lifespan
- ✓ Optional ZWS40G variant with GPS/4G
