Industrial Moisture and Humidity Measurement (eBook)

Dr. Roland Wernecke has been the manager of a company which develops and manufactures moisture measurement devices for industry and laboratories for over 20 years. He obtained his academic degrees from the University of Dresden and the Academy of Science, Germany. Dr. Wernecke is a member of numerous technical committees and organisations for standards. He advises companies and organizes seminars and workshops on moisture and humidity measurement for industry and research. He is involved in numerous cooperations with institutes and universities in the development of new methods for the measurement of moisture and humidity in gases, liquids and solid materials. Jan Wernecke is a physicist at the Physikalisch-Technische Bundesanstalt, the German national metrology institute, where he is currently finishing his PhD thesis. He studied physics at the Friedrich-Schiller University in Jena, at the Université Joseph Fourier Grenoble, and at the Australian National University in Canberra. He gained experience in the fundamentals and practical aspects of moisture and humidity measurement during various project works, for example on ambient climate monitoring and on the survival of organisms in a simulated Mars atmosphere.
