The NOAH II All-Weather Precipitation Gauge
Each of the 12-inch, 20-inch, 30-inch, 180-inch capacity models has 12-inch diameter collection chambers. The base enclosure provides housing for a battery and the load cell.
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.

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
