Page 9: Purpose
Purpose The Multitec 545 and the 540 version are gas measuring de- vices for monitoring gas mixtures that are formed in biological processes (biogas, landfill gas). They measure the concentration of several gases in the gas mixture simultaneously. The devices are ideal for use in waste disposal sites, sewage plants and bi- ogas plants. -
Page 10: Intended Use
Intended use This device is intended for professional residential and commer- cial use including small firms and commercial operations. The ap- propriate specialist knowledge is required to operate the device. The device may be used to measure the following gases (de- pending on the sensors fitted). -
Page 11: General Safety Information
● Observe the relevant safety regulations when working at agri- cultural biogas plants /1/. ● When working in closed spaces, these must be well ventilated. SEWERIN recommends: For measurements in closed spaces, attach the gas outlet adapter to the device to reduce the risk of high concentrations at H S. -
