Featured Product
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.
Featured Product
OFS-2000 Optical Flow Sensor
OSi's patented Optical Flow Sensor (OFS) measurement is a instantaneous cross stack line average. OFS measures velocities from .03 -170 M/sec with a 2% +/- accuracy. OFS measurement technique has zero effect from changes in temperature, pressure, humidity, or gas composition. and is a non-intrusive measurement.
