Emission and raw gas monitoring

Indispensable for environmental protection

Industry and transport are the main sources of environmental pollution caused by emissions. The monitoring of and adherence to limit values serves to protect our environment – a responsibility of society as a whole, and one that is also made clear by the steady and continuous tightening of environmental and safety requirements. We have dedicated ourselves to fulfilling this responsibility with future-oriented solutions in emission measurement technology and raw gas monitoring.

Documenting and verifying emissions

Operators of industrial plants emitting air pollutants are obliged to measure their emissions. Limit values set out in relevant laws and regulations have to be adhered to and monitored by operators and the results of their monitoring have to be passed on to the competent authorities. Our products for the exact measurement of emissions from industrial plants are suitability-tested and certified for official emission monitoring.

A one-stop source for all technologies

The DURAG GROUP has an extensive product portfolio and decades of experience in the field of emission monitoring. The solutions available from our companies DURAG, DURAG DATA SYSTEMS and AP2E include durable and low-maintenance measuring devices for all requirements. They enable application-based selection of different methods for the measurement and monitoring of the dust concentration and volume flow in flue gas and for continuous mercury and multi-component gas analysis.
