Fully configurable for your application
The GM25-2 is designed to adapt to your monitoring requirements. With configurable infra-red and electrochemical channels, optional N2 balance calculation, and pressure measurement capabilities, it can be tailored to suit landfill gas analysis, biogas monitoring, wastewater treatment, and industrial compliance applications.
Multi parameter measurement in one instrument
In addition to multi-gas analysis, the GM25-2 can be expanded to measure atmospheric, static and differential pressure. Optional vane anemometer and temperature probe attachments allow operators to capture velocity and temperature data, reducing the need for multiple instruments on site.
Streamlined reporting with DataField GM25 Connect
The GM25-2 can operate as a standalone analyser or integrate with the DataField GM25 Connect app. Using a mobile device or tablet, users can configure measurement routines, control the analyser remotely and streamline reporting. This results in faster operations and more flexible data capture tailored to the individual user’s needs.
