Multitec 545


Multi-gas measuring device with infrared sensors and extended measuring range for hydrogen sulfide


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 use of infrared measuring techniques for methane and carbon dioxide eliminates the possibility of misleading results due to interaction with other gases. The large screen allows all parameters to be displayed simultaneously and quickly read off at a glance.

Measurement data is stored in log files and can easily be transferred to a PC via a USB connection.
