  APG-815 All Precipitation Gauge

 • Easy Installation
 • High Sensitivity
 • Low Maintenance
 • Minimal Wind Effects
 • Wide Dynamic Range
 • No Evaporation or Splash Errors
 • Works on Ships & Buoys
 • Operates constantly 24/7/365

The APG-815 builds on all the advantages of OSi’s patented optical rain gauge technology. APG-815 includes calibrated water equivalent snow rate and accumulation output. Adaptive Heater Technology (AHT) control of lens heaters minimizes power required, making the APG-815-DS practical for solar power applications. With GPRS/GSM modem add-in, the APG-815 may be deployed anywhere a cellular data connection is available. Real time precipitation data is also available over internet connection. The APG-815 is the sensor of choice for remote rain/snow gauge networks.
