The GA5000 is a portable gas analyser specifically designed for landfill and contaminated land monitoring, providing reliable and precise measurement of multiple gases.

Highly reliable, certified portable gas analyser for landfill and contaminated land monitoring.

Key Features

Certified: ATEX, IECEx, CSA, MCERTS, and UKAS calibration (ISO17025)
Measures methane (CH4), carbon dioxide (CO2), oxygen (O2)
Barometric and relative pressure measurement
Simultaneous display of all gases with peak and previous readings
Choice of user settings, simple gas reading, and profiling function
Up to 6 gases monitored with modular, upgradeable design
3-year warranty and robust, market-leading reliability
Memory: Stores 2,000 IDs* and 4,000 readings (*with GAM software)
Data logging, profiling, and easy data transfer
