The NOAH II All-Weather Precipitation Gauge
Each of the 12-inch, 20-inch and 30-inch capacity models ha s 12-inch diameter collection chambers. The base enclosure provides housing for a battery.Periodic servicing involves manually draining the collection chamber and adding proper amounts of antifreeze and evaporation-suppressant oil. Catch capacities are dependent on low temperature extremes and required antifreeze to maintain a liquid solution. Advanced Features of the NOAH II: • Uses proven load cell technology • Advanced digital software filtering reduces errors due to wind, vibration and other noises sources • Environmentally friendly ethanol-glycerin antifreeze converts frozen precipitation to liquid • Low power requirement allows standalone operation from optional solar power system • Measurement unaffected by high precipitation rates • Delivered fully calibrated from the factory • Test interface to gauge electronics Specifications: Resolution 0.01 inchThreshold 0.01 inch Accuracy +/- 0.01 inch Temperature Range -30 C to +50 C Power Requirement +12 VDC (15 ma average drain) Orifice (diameter) 12 inches Capacities: 12, 20 and 30 inches Overall Height (30-inch model) 54 inches Overall Height (20-inch model) 44 inches Overall Height (12-inch model) 34 inches Options: Windscreen - to reduce effects of wind on measurement. The windscreens are made of GE LEXANTM a space-age material resistant to weather and solar radiation. Solar Power System - consisting of a 20-watt, 12-volt solar panel, regulator, and a 12-volt, 12-amp battery. (Back to NOAH Precipitation Gauges)
