About Döscher Microwave Systems
Döscher Microwave Systems is a provider of microwave-based measuring systems for continuous moisture, density and basis weight measurement in industrial production processes. The company has 30 years of experience in density-independent moisture measurement. The technology used is based on a 2-parameter microwave resonance method that enables contactless measurement of surface and core moisture independently of material density, fill height, color and surface. The systems are used inline in the production process or offline in the laboratory and can be integrated modularly into new plants and retrofits. Fields of application include wood-based materials, solid wood, veneers, laminates, parquet, glulam, biofuels, bulk materials, building materials, animal feed, food products, pharmaceutical products as well as paper, cardboard, films, textiles and nonwovens. In addition to hardware, the company offers individual consulting, software (MoistureScan), technical support services including remote maintenance, and customer-specific special solutions. The company is located near Hamburg.
