**NEW** GFM435 with MCERTS Approval

Gas Analyser and Flow Meter

Optimised for site investigation and Landfill Monitoring

Main Features

• 5 gas analysis as standard (CH4,LEL(CH4),CO2,O2,CO and H2S) 2 further optional gas channels.
• Borehole flow, borehole pressure and atmostpheric. pressure measurements.
• Optional temperature and velocity measurement.
• All gas and flow channels MCERTS certified.
• Hexane equivalent measurement of hydrocarbon vapours from common liquid fuel and oil spills.
• Display of PID compensation factors for accurate operation of PID sensors in CH4 rich atmostpheres.
• Intrinsically safe EEx ib T1.

HEXANE Channel

With the GFM435 when and if the Methane sensor shows an  over-range signal or abnormally high value (a good indicator that other hydrocarbons are present in a borehole) the Hexane value will remain valid and in range up to 2.000% allowing standarised monitoring of other hydrocarbon vapours as a persentage of Hexane vapour equivalent.
