Pillard Opastop® GP3050ST Dust monitor for tunnels and parking spaces Ultimate dust monitor for real-time measures in traffic roads • Accurate and continuous measures • Easy installation and maintenan

Pillard Opastop® GP3050ST is the ultimate solution to measure pollution level in traffic areas (road and train tunnels, underground car parks), ensuring air quality and visibility. The air sample drawn through an integrated fan crosses a measuring vessel fitted with a high power light emitting diode and a measuring cell. This cell positioned at 90 degrees to the emitting diode estimates opacity by the reflection of light on the particles in suspension. A second cell located opposite the emitting diode is used to monitor and quantify the optics fouling to automatically correct any drift. CONTACT...
