gas analyzer / process gas / methane / oxygen

ZPAF gas analyzer can simultaneously measure the concentration of CH4, CO2, H2S and O2 components in the biogas.
ZPAF provides high-stability and ease-of-maintenance incorporated into a space-saving design.
CH4 and CO2 are measured by non-dispersive infrared method (NDIR). O2 and H2S are measured by electrochemical method. H2S measurement range is up to 5000 ppm.

FEATURES

1. Very high sensitivity:
- with the brand new mass flow sensor
