Introduction to MGP260 series
Vaisala CARBOCAPâ MGP260 Series Multigas Probes for Methane, Carbon Dioxide, and
Humidity Measurement are compact and durable in-situ probes for methane (CH
dioxide (CO ), and humidity (H

conditions. MGP260 series probes are Ex certified for use in Ex Zone 0 (parts inserted into
process) and Ex Zone 1 (parts outside the process).
The MGP260 series includes two probe variants for different biogas process measurement
applications. MGP261 is targeted at raw biogas measurement, whereas MGP262 is intended for
offgas measurements in biogas upgrading facilities. All MGP260 series instruments are
designed to be installed directly in the process gas pipeline, removing the need for sample
treatment.
The application areas of the MGP261 variant include anaerobic digestion of industrial and
municipal waste and sludge from waste water treatment, landfill gas monitoring, activated
carbon filter monitoring in biogas treatment process, and CHP engine feed gas monitoring.
MGP262 probes are optimized for measuring methane concentrations below 5 vol-% and CO2
concentrations above 90 vol-% in the offgas stream, making them ideal for a wide range of
upgrading technologies and processes.
The MGP260 series proprietary infrared technology provides superior stability and
repeatability. Thanks to condensation elimination through probe heating and corrosion-
resistant steel and plastic materials, the IP66-rated instruments are highly robust and durable.
MGP260 series measurement output options include 3 analog current output channels (4 ... 20
mA) and Modbus RTU over RS-485. The probes also provide a 4 ... 20 mA Ex ia input for
connecting an external pressure or temperature sensor.
For easy-to-use access to configuration, diagnostics, and calibration and adjustment
functionalities, MGP260 probes can be connected to Vaisala Insight PC software with a USB
cable accessory.
