Optical Scientific Inc. (OSi) is a research and development firm that provides a full product line of advanced weather sensors to and Automated Weather Observation Systems (AWOS) for both fixed operational and tactical applications.

OSi sensor products are designed to be reliable, accurate, and hassle-free. Rugged and durable construction enables them to endure harsh weather conditions from searing heat to arctic ice and last for decades. Our products are easily installed and require virtually no maintenance by using built-in self-diagnostics and testing—typically able to operate remotely for months on end. To provide field-proven, highly accurate data, our sensors utilize advanced scintillation technology and intelligent algorithms based on over 200 million hours of OSi sensor field data.

The OWI-650 measures visibility and detects and quantifies rain, snow, drizzle, and freezing and mixed precipitation conditions.  Thanks to its small and light-weight design, it can be quickly deployed anywhere it’s needed. The OWI-650 reports over 50 NWS / WMO Present Weather codes and is DSP-based–no field calibration required.

OWI-650 is able to operate off solar, battery or AC power. Per your needs, other sensors can easily be added, including: wind, temperature, relative humidity, and barometric pressure. Other options include: solar power kits, portable tripods and data radios.

The LOA-005 simultaneously measures the average winds across the beam (crosswind) and the turbulence (CN2) over the measurement path. Path-averaged wind sensors offer vast improvement over a single point wind sensor for large area wind studies. 

The LOA-005 can be operated from buildings or used as a single point installation using retro-reflectors on towers to measure vertical wind profiles. It has an ultra-low wind threshold of 0.001 m/s, provides long-range measurement (from 200 yards to 9 miles), and by using two or more path measurements, the LOA-005 can measure two dimensional wind profiles plus convergence and divergence within a large enclosed area.
