4 | Measuring + Monitoring The world is growing together and the global exchange of goods and services is a major contributing factor. Industry and transportation are the main sources of harmful emissions that cause environmental pollution. To protect the environment, more and more countries are defining limit values for specific pollutants, which must be continuously monitored. For this purpose we offer comprehensive solutions for the precise measurement of emissions from industrial plants, as well as for monitoring air quality in tunnels. Highlights in Measuring + Monitoring § We offer durable,...

5 | Measuring + Monitoring Product Groups With over 70 years of technical experience we offer our customers inclusive solutions for any measuring challenge. Dust Monitors Mercury Analysers Our products continuously and precisely measure dust concentrations in dry and wet gases. They are low maintenance, fully certified and extremely robust. Thereby, these monitors are designed according to the latest technology standards. Our products for total mercury measurement also allow specification of elemental and oxidised mercury. This option can ideally be used for process optimisation. Volume Flow...
