HOBO® U30-NRC Data Logger
U30 USB Weather Station Data Logger
This rugged weather station is Onset’s most durable outdoor
environmental monitoring solution. Users can easily configure the
HOBO U30-NRC Weather Station to fit their application needs. Use
up to 15 channels to collect environmental data and then upload to
HOBOware® software for analysis. HOBOware Pro is
recommended for extended features, see the comparison here. The
U30-NRC has four configurable systems, that can be configured
below, that consist of the following part numbers: U30-NRC-000-05S100-000, U30-NRC-000-10-S100-000, U30-NRC-VIA-05S100-000, and U30-NRC-VIA-10-S100-000.
Supported Measurements:
