The Data Logging Rain Gauge is a battery-powered rainfall data collection and recording system which includes a HOBO® Pendant Event data logger integrated into a tipping-bucket rain gauge. This model automatically records up to 3200 mm of rainfall data that can be used to determine rainfall rates, times and duration. Also records temperature when used with an optional solar radiation shield (RS1 Solar Radiation Shield, or M-RSA). A base station or shuttle is required.
Environment:The RG3-M Data Logger is for use in Outdoor environments
Measurements:The RG3-M Data Logger supports the following measurements :
Maximum Rainfall Rate: 12.7 cm (5 in.) per hourCalibration Accuracy: ±1.0% (up to 1 in./hour for the RG3 or 20 mm/hour for the RG3-M)Resolution: 0.01 in. (RG3) or 0.2 mm (RG3-M)Calibration: Requires annual calibration: can be field calibrated or returned to the factory for re-calibrationOperating Temperature Range: 0° to +50°C (+32° to +122°F)Storage Temperature Range: -20° to +70°C (-4° to +158°F)Environmental Rating: WeatherproofHousing: 15.24cm (6-in.) aluminum bucketTipping Bucket Mechanism: Stainless steel shaft with brass bearingsDimensions: 25.72 cm height x 15.24 cm diameter (10.125 x 6 in.); 15.39 cm (6.06 in.) receiving orificeWeight: 1.2 Kg (2.5 lbs)Part Numbers: RG3 (0.01 in. per tip), RG3-M (0.2 mm per tip)The CE Marking identifies this product as complying with all relevant directives in the European Union (EU).
