Weather Station Data Logger (U30-NRC) HOBO

Overview

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.

• All electronics are housed within a rugged double-weatherproof, tamper-proof enclosure
• Setup is quick and easy with plug-and-play sensors
• Fast data offload via USB
• Optional analog inputs with sensor excitation
