Brand:SODI
Model:CVD
SODI COVI detector is specially used for highway tunnel environment monitoring, carbon monoxide concentration can detect coefficient of visibility to keep the all-weather real-time detection of tunnel coefficient of CO concentration and visibility. To achieve energy saving operation and keep the fan operates with better life; according to different locations, in the event of a fire, the corresponding fire smoke extraction processing ensure the safety of the tunnel and operating environment of comfort. Its professional tunnel design is perfectly using high precision technology, completely avoid the environment problems such as the impact on the equipment, and available to make the equipment under harsh conditions of a continuous and reliable operation.
