A miniature, Bluetooth, Battery powered, ultrasonic anemometer and wind vane.

Built with ULTRASONIC sensors, with no moving parts to make it robust and dependable, the Ultrasonic Portable Mini is a wind meter that measures both speed  and direction, allowing data logging via a free app.

With just 43 mm diameter the Ultrasonic Portable MINI is a fully handheld, complete wind instrument.

It's size makes it an ideal  stand-alone wind meter of great value on a wide range of industries and applications.

The Ultrasonic portable MINI has a female thread (1/4") perfect to be mounted on any tripod. 

For those who want to see/read data while using Anemotracker App, the Phone Mount is the solution. A tiny accessory to put in the headphones hole there is in any Android phone.

Wireless and Battery Powered

Wireless Charging QI- thanks to its Bluetooth connection, the Ultrasonic Portable Mini can be recharged on a wireless charged pad connected via USB to the power. 

No data wires, but connectable to your network: its bluetooth connection avoids the hassle of wiring it to a display. Still, if you want to connect the Ultrasonic Portable to a display or network, you can use one of our gateways: the NMEA Connect Plus gets the Portable Bluetooth signal and converts it to a wired or NMEA0183 or NMEA2000 signal. It also relays the Bluetooth signal and casts NMEA0183 data via WiFi.
