Biomethane analyzer GA220 Biomethan

monitoringprocessfor quality control

The GA220 Biomethane is a methane analyzer for fast online measurement of CH4 and CO2 in biomethane, with a new reading every second from a 19-inch rack unit. It is designed for plants that need low detection limits on the methane and CO2 content but no compensation of further interfering gases.
Typical applications:

• Biomethane plants: methane concentration measurement of the product gas
• Biomethane CHP units
• Power-to-gas plants
• Biogas plants
• Fuel cells and gas heat pumps

What operators get:

• Expanded measurement uncertainty of 0.2 % of full scale for CH4 in the 90–100 vol.% range
• NDIR dual-beam method with cuvette heated to 50 °C, patented reference pressure measurement and pressure compensation
• Ready to measure 5 minutes after switching on
• 19-inch format that fits into existing analyzer cabinets; internal pump optional
• RS232 as standard; Profibus DP, Modbus TCP, EtherNet/IP, Profinet and up to 8 analog 4–20 mA outputs as options
• For wall mounting with additional O2 and H2S measurement and automatic calibration, see the BioBasic Biomethane
