With the Multitec 545, up to five gases can be measured simultaneously. The very high H2S concentrations in wastewater treatment plants and palm oil factories, for example, place special demands on the measuring instrument. With its rugged design and wide H2S measuring range, the Multitec 545 is ideal for this use. The Multitec® 560 is a combined gas warning and measuring device. When used as a gas warning instrument it reliably and automatically detects gases which are toxic and hazardous to humans. When used as a gas measuring device it records and documents the composition of biological process gases. Biological processes generate gas compositions that make special demands on measuring equipment. The robust Multitec® 540 provides the ability to measure six gases simultaneously.
