Measurement made easy

Overview

The ABB LGR-ICOS gas analyzers build on the heritage and extensive track record of Los Gatos Research analyzers, using patented Off-Axis Integrated Cavity Output Spectroscopy (OA-ICOS) technology, the latest evolution in tunable diode laser absorption spectroscopy.

ABB’s new microportable gas analyzers (M-GGA-918 and M-GPC-918) report measurements of methane, carbon dioxide and water vapor simultaneously in a package that is compact, crushproof and travels anywhere. Small enough to be hand-carried (even on-board aircraft) and requiring less than 35 watts, the M-GGA-918 and M-GPC-918 offers opportunities to measure greenhouse gases anywhere.

As with all LGR-ICOS analyzers, the M-GGA-918 and M-GPC-918 are fast and simple to use which makes them ideal for field studies, compliance monitoring, air quality studies and soil flux studies, and wherever sensitive measurements of greenhouse gases are needed.

Features and benefits

• Lightweight: less than 5.5 kg (12 pounds) with battery (included)

• Continuous measurements

• Data reported every second with high sensitivity

• Ideal for soil flux studies and field measurements of greenhouse gases

• Extremely wide linear range, CH₄ range up to 4% flammability limit (optional)

• No cross interferences

• Operates directly on DC power

• Fast gas flow response time (1 second, 1/e)

• Records data within 20 seconds after power on

• Multiple data outputs and internet connectivity

• Recirculating capabilities (inlet/outlet)
