Optical Scientific, Inc. (OSi), founded in 1985, is a sensor manufacturer and engineering firm located in the I-270 high-technology corridor in Maryland. The company designs non-contacting electro-optical devices that measure air and gas flow, wind, turbulence, liquid and powder tank levels, visibility, and precipitation type and amount. OSi has become synonymous with advanced optical instrumentation. Its sensors and systems are trusted worldwide, serving critical needs at refineries, smelters, power plants, large boilers, airports, highways, railroad tracks, ocean-going ships, buoys, and hundreds of other commercial and industrial sites, from Alaska and China to Antarctica. OSi sensors are engineered for maximum performance, wide dynamic range, extremely harsh environments, long service life, and easy installation and operation. For nearly three decades, the company has been developing innovative products to meet the complex demands of remote sensing, measurement, data collection, and communications in the 21st century. Its products and capabilities include environmental instruments (optical anemometers and optical flow sensors), laser level meters, weather instruments (crosswind, turbulence, rain, snow, visibility, and present-weather sensors), modular automated weather observing systems, low-cost portable weather stations, and a wide range of systems engineering, field testing, installation, training, and support services—all backed by excellent customer service.
