Environmental dust monitors
![Feinstaubmessgeräte](/statics/durag_com/images/Teaserbilder/Produkte/edm264_persp_cgi_1110x740_rdax_80.webp)
PM measuring systems from the DURAG GROUP precisely measure the particle number size distribution of dust and ultrafine airborne particles.
Gas sensors
![Gassensor smart/ECS](/statics/durag_com/images/Teaserbilder/Produkte/smart_ecs_persp_cgi_1110x740_rdax_80.webp)
Our precise, low-maintenance and IoT-capable “smart/ECS” gas sensors are designed for easy handling and flexible integration into tunnel control systems.
Visibility monitoring systems
![Sichttrübungsmessgeräte](/statics/durag_com/images/Teaserbilder/Produkte/smart_aqm_persp_cgi_1110x740px_rdax_80.webp)
For visibility monitoring we offer sensors with two different measuring methods: the traditional transmission method and the more modern scattered light method.
Air flow monitoring systems
![Luftströmungsmessgeräte](/statics/durag_com/images/L%c3%b6sungen/Produktbilder%20Industrien/t_fl_dp_persp_cgi_1110x740px_rdax_80.webp)
For air flow monitoring, we use systems with two different measurement methods: the ultrasonic transit time difference method and the differential pressure method.
Luminance meters
