Industrial wallmount analyzer
LGR-ICOS™ GLA531 Series

LGR-ICOS GLA531 (previously 950 Series) laser process analyzers accurately measure gas concentrations with extraordinarily high sensitivity, fast response and over a wide dynamic range in both simple and complex mixtures.



With no consumables or frequent calibration requirements, LGR-ICOS laser process analyzers can significantly improve process monitoring and control of refining and petrochemical applications as well as accurately measure trace gases in syngas, regeneration hydrogen and inert gases.

The GLA531 series delivers: 

  • measurement of multiple gases
    – fast response (seconds)
    – high sensitivity (ppb levels)
    – high accuracy in complex gas matrices
  • Low total cost of ownership 
    – Low operational costs (no consumables) 
    – High reliability (few moving parts) 
    – Easy to service 
  • Simple to operate
    – Easy Set-up 
    – Operation through the LCD touchscreen display
    – Contextual system diagnostics
    – Reduced maintenance effort
  • Global approvals for explosion protection
