Microportable gas analyzers

GLA131 Series

Sensitive, precise, accurate, highly linear (wide dynamic range) and fast.


Pre-calibrated analyzer in extremely compact crushproof enclosure weighing less than 6 kg. Operates directly on AC or DC power. Battery recharges when analyzer connected to AC. System includes all software for analysis and an internal vacuum pump for less than 0.4 second gas flow response.


Our offering

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 microportable gas analyzer reports measurements of various gases 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 Microportable offers opportunities for measurements anywhere.

As with all LGR-ICOS analyzers, the Microportable is fast, simple to use and offers the best overall performance, which makes it ideal, but not limited to, field studies such as:
  • Soil flux measurements
  • Greenhouse gas monitoring
  • Natural gas leak detection
