About Döscher Microwave Systems
Döscher Microwave Systems specialises in density-independent moisture measurement using microwave technology and can look back on around 30 years of experience in this field. The company develops and manufactures measurement systems that capture moisture, density and basis weight continuously and in real time – both inline in the production process and offline in the laboratory. The measurement technology is used, among other things, in the wood industry (wood-based materials, solid wood), for biofuels, animal feed, foodstuffs, construction materials, bulk goods, pharmaceutical products and for web-shaped materials such as paper, films, nonwovens and textiles. In addition to hardware manufactured in-house, the company offers consulting, the development of customised measurement concepts, integration into existing plants and technical support including remote maintenance. The company is based in Hamburg.

Materials and Measurement Methods
Moisture measurement (microwave, density-independent)
Density-independent, non-destructive measurement of moisture content inline in the process or offline in the laboratory.
Density measurement (non-contact)
Non-contact density determination of bulk goods, pastes and solid materials directly in the process.
Basis weight measurement
Continuous capture of basis weight for assessing layer thickness and uniformity.
Laboratory measuring devices
Non-destructive moisture measurement for samples, recipe development and validation of process values.
