About ACP Environment AG/SA
ACP Environment AG/SA is a Swiss company headquartered in Sutz-Lattrigen (BE), specialized in tunnel sensor technology and complete sensor solutions for road and tunnel infrastructure. The company develops and manufactures its own measuring devices and control systems, including visibility turbidity meters (opacimeters), smoke detection systems, luminance meters, ultrasonic anemometers, traffic counting and classification systems, weather monitoring stations as well as sensors for temperature, humidity and air quality (CO, NO, NO₂). In addition to product development, ACP offers plant engineering, installation, commissioning, maintenance and long-term technical support as well as ready-to-use turnkey solutions. Facility management includes maintenance, upkeep and repair of tunnel sensor technology around the clock. Customers include public authorities, infrastructure operators and general contractors; the company is represented in practically all tunnels in Switzerland and active throughout Europe. References include more than 500 road tunnels and over 9,000 delivered, installed and maintained sensors.
