Measure and monitor dust emissions, detect oil on water



Environmental technology in industry

Industry and traffic are the major emission sources of our time. Schmachtl offers solutions for measuring and monitoring dust and gas emissions, dust filters and the absence of oil in rivers and lakes.

Oil leaks or oil spills in industrial plants are a major threat to our environment. Discharges into rivers and lakes must always be monitored for freedom from oil. Depending on the application, the appropriate measurement method must be used. To determine the dust or gas concentration in industrial plants, processes or procedures, different measurement methods are designed, installed and periodically maintained.

General information about oil warning devices

Our partner in monitoring tasks is CHEMTRONIC, a pioneer in the field of optical process measurement technology. We sell, install and service various oil monitors and oil scanners for detecting oil in water. Our oil monitors detect even small amounts of oil. Other product lines include in-line turbidimeters and photometers (VIS, NIR and UV). In addition to traditional optical technologies, we offer an easy-to-install, virtually maintenance-free ultrasonic turbidity measurement system. This technology is not affected by product color or coating formation.
