Gas Data GM25-3 Portable Landfill Gas Extraction Analyser

• Landfill gas extraction

The GM25-3 is an ATEX certified landfill gas analyser providing fast and accurate measurements of gas and pressure.

It is a fixed configuration that measures 5 gases, using a combination of IR and EC channels. It also provides three different pressure measurements: Atmospheric; Static (Gauge); Differential. Flow rate is derived from a calculation using differential pressure.

Optional extras to measure velocity and temperature are available.

DataField GM25 Connect

The GM25 series can be used by itself or in combination with the DataField GM25 Connect app which allows the GM25 analyser to be controlled via a mobile device or tablet. This results in faster operations whilst being able to configure how readings are taken suiting the individual users needs.
