Optical Scientific Inc. (OSi) products

OSi`s APG-815-DS (All Precipitation Gauge) uses proven optical scintillation technology and offers many performance and maintenance advantages over traditional tipping bucket and weighing type rain gauges. In addition to rain and snow water equivalent rate and accumulation the APG-815-DS report present weather codes in NWS and WMO formats. Traditional rain and precipitation gauges cannot report present weather codes. Adaptive Heater Technology (AHT) is used to conserved power. The lens heaters are only energized when needed. This mean the APG-815-DS is appropriate for solar powered installations. Solar power combined with OSi cellular phone makes the APG-815-DS ideal for remote installations and networks.

OSi`s ORG (Optical Rain Gauge) is a superior tool for rain measurement. The ORG® is the only instrument available to measure true rain rate. This means you avoid the reading errors due to mechanical limitations, which plague other low-tech gauges. No other rain sensor comes close to the ORG in  performance and features. Our scintillation technology has undisputed advantages over the competition.
