GA-60 portable flue gas analyser
GA-60

Portable flue gas analyser using electrochemical and IR gas sensors.

The GA-60 is a high-quality instrument produced with use of the latest technical discoveries. In addition to its exceptional measurement abilities it is also handy and easy to use.

The instrument is fitted with 5 electrochemical sensors as standard. A further 2 electrochemical sensors and 3 infrared sensors can be added. The modular construction allows the instrument to be configured for nearly every customer requirement. The instrument also has various analog inputs and outputs to enable easy data transfer and documentation.Constructed to be compliant with EN50379.
