Gas Analyzer GA220 Biomethane Data Sheet

Product catalog summary

Overview: The Gas Analyzer GA 220 is designed for fast and simple online measurements of biomethane concentrations, specifically CH4 and CO2, with high accuracy and low detection limits. It is suitable for various applications including biomethane plants, CHP, power-to-gas plants, biogas plants, fuel cells, and gas heat pumps.

Advantages:

High long-term stability and low calibration effort due to patented NDIR measurement method.
User-friendly operation with direct measured value display via touch panel.
Flexible data transmission through open interface architecture (standard RS232).
Low service costs due to reduced maintenance requirements and high operational reliability.
