Hobo U30-NRC – Onset

USB weather station data logger (15 channels)

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. The setup is quick and easy with plug-and-play sensors and you can offload via USB optional analog inputs with sensor excitation. This weather station includes relay that can be activated on user-defined alarm conditions.

This data logger operates in indoor and outdoor environments. The data logger supports the following measurements: 4-20mA, AC Current, AC Voltage, Air Velocity, Amp Hour (Ah), Amps (A), Barometric Pressure, Carbon Dioxide, Compressed Air Flow, DC Current, DC Voltage, Dew Point, Differential Pressure, Gauge Pressure, Kilowatt Hours (kWh), Kilowatts (kW), Leaf Wetness, Light Intensity, PAR, Power Factor (PF), Pulse Input, Rainfall, Relative Humidity, Soil Moisture, Solar Radiation, Temperature, Volt-Amp Reactive, Volt-Amp Reactive hour, Volt-Amps (VA), Volts (V), Water Flow, Water Level, Watt Hours (Wh), Watts (W) and Wind.
