Vaisala MGP241 MGP241 Multigas CO2 Probe for CCUS

CARBOCAP® MGP241 Multigas Probe for Carbon Dioxide and Humidity Measurement is designed for continuous measurement of carbon dioxide (CO2) and humidity (H2O vapor) measurements in industrial processes, especially in carbon capture, utilization and storage (CCUS) applications. It is designed to be installed directly in the process gas pipeline, removing the need for sample treatment.

Heavy-duty performance

The new MGP241 is the smartest solution for process CO2 measurement. From carbon capture to general industrial use, it's built to endure and excel in the harshest environments.

Superior reliability, direct in the process

Exceptionally compact, light and operationally optimized. Requires only minimal maintenance and calibration. Demonstrated field-proof and IP65-rated technology. Built on 85+ years of measurement expertise.

Plug-and-play operation + high connectivity

Its compact size and plug-and-play design make installation radically easier. It integrates into your existing operational systems with minimal effort. Both digital Mo® and analog SCADA communications are supported. The MGP241 is fully compatible with the Indigo family of transmitters for remote data connection and local graphical display.

Features:

• Continuous process monitoring for carbon capture, utilization and storage (CCUS) applications
• Direct installation into process: no moisture removal or other sample treatment needed
• Standalone probe with digital Modbus® RTU over RS-485 and 3 analog outputs (4-20 mA) 
• Analog input (4-20 mA) for external temperature or pressure compensation for more accurate measurement
• Available measurement parameters: carbon dioxide (CO₂) and humidity (H₂O vapor)
• Compatible with Vaisala Insight PC software and Vaisala Indigo80, Indigo300, and Indigo520

2-in-1 measurement probe

The MGP241 probe measures carbon dioxide (CO₂) and humidity (H₂O vapor) in demanding conditions. MGP241 measures carbon dioxide and humidity in vol-% or ppm by volume units, or alternatively dew point temperature (T_d) and frost point temperature (T_f). The patented CARBOCAP infrared technology enables simultaneous detection of multiple gases unlike the traditional non-dispersive infrared (NDIR) measurement technique. This allows compensation for sensor drift, sensor aging, and for any crossinterference effects between measured gases. Calibration gases are not needed for routine operation; a functional check and drift check every 12 months is recommended.

Continuous process monitoring

MGP241 measures gases directly in the process without a need for drying or other sample treatment. This simplifies the installation and minimizes the footprint of the measurement solution compared to traditional gas analyzers. The rapid measurement cycle takes only seconds, providing direct real time measurements for process control and monitoring. The CO₂ measurement can be shown either as wet basis or dry basis values. Thanks to the built in temperature and pressure compensation algorithms, and the CARBOCAP infrared technology, the measurement is stable and reliable across a wide range of process and environmental conditions.

Flexible connectivity

The MGP241 probe has 3 4−20 mA analog outputs for CO₂ and H₂O vapor concentrations and for retransmission of analog input, as well as a 4−20 mA analog input for external pressure or temperature signal used for compensation. The probe also offers Modbus RTU protocol for digital connectivity. For easy-to-use access to configuration, diagnostics, and calibration and adjustment functionalities, the MGP241 probe can be connected to Vaisala Insight PC software with a USB cable accessory, and it can also be connected to Indigo devices: Indigo80, Indigo300, and Indigo520.
