U30 USB Weather Station

Sale priceR 18,278.40



A rugged weather station for outdoor environmental monitoring. Easily configurable for specific application needs, with up to 15 channels to collect environmental data and then upload it to HOBOware software for analysis. HOBOware Pro software is recommended for extended features. This station is available in two models: the U30-NRC-000-10-S100-000 and the U30-NRC-VIA-10-S100-000, which include two analog inputs.
