Open Path Gas Detector · Gas Detection
Dräger PIR 7200 Open Path is a open-path gas-detection system. It is normally installed across a defined hazardous-area line of sight between optical transmitter and receiver units. Its primary purpose is to detect gas clouds over a path rather than only at a single point. Compared with point detectors, open-path systems monitor an extended optical beam and are especially sensitive to alignment, obstruction and window contamination. For exact ratings, dimensions, settings, capacities, materials and variant-specific limits, refer to the manufacturer documentation for the exact figure.
