Sentry-MS

The Cerex Sentry-MS is a mono-static, open-path air-monitoring system that uses ultraviolet light to analyze the air for hazardous pollution and airborne toxins. Easy to use and portable, the Sentry-MS can continuously monitor one-way path lengths up to 1000 meters; a 2000 meter optical path length. The monostatic design of the Sentry-MS eliminates the need for power at both ends of the path. The Sentry-MS offers real-time detections of compounds from the parts-per-trillion to percent concentration level.
