With a total weight of around 13 kg (36.5 lb), the station is specifically designed for ease of transportation, rapid deployment and quality of measurement. It is supplied in two customised carry bags plus a separate weather-proof case, all of which can be carried together by one person when necessary. Nomad is intended to satisfy YOUR professional monitoring needs. Once on site, the Nomad can be deployed and collecting data in less than five minutes.
