The World Leader in Optical Sensor Innovation
Our name has become synonymous with advanced weather/environmental instruments that open a new avenue to twenty-first century technologies. OSi's instruments and systems work reliably for unattended field operations - 24 hours a day, 7 days a week - and often in critical areas such as airports, along highways and railroads, in forests, on data buoys in the middle of oceans, and even in the Antarctic.
APG All Precipitation Gauge APG-815
OSI’s APG-815-DS uses proven optical scintillation technology and offers many performance and maintenance advantages over traditional tipping bucket and weighing type rain gauges.
OFS-2000 Optical Flow Sensor
OSi's patented Optical Flow Sensor (OFS) makes drift-free measurements across the entire stack, duct or pipe diameter and calculates an accurate average flow reading.
