Find leaks fast

  • Performs measurements while driving at speeds up to 55 mph (88 km/h)
  • Survey mains and services with the same drive by
  • Identifies attributes of emissions sources by measuring methane and ethane simultaneously
  • Shares survey data with MicroGuard™ to enable pinpointing of leak emissions sources in minutes

Find more leaks

  • ABB’s patented technology uniquely combines high sensitivity and accuracy with ruggedness and reliability.
  • Reports both methane and ethane simultaneously to eliminate false positives
  • Ultra-high (single parts-per-billion) precision and sensitivity allows detection of dangerous buried or hidden leaks and from distances up to 600 feet away.
  • No need for high-pressure gas cylinders on board (in contrast to other laser-based systems).
  • ABB’s proprietary algorithms (fluid dynamics models) combined with fast flow response yields accurate leak localization and size estimates.
  • Unparalleled data integrity and cyber security: ABB systems satisfy cyber security requirements and ABB customers own all data.
  • MobileGuard™ can share data with ABB’s MicroGuard™ to pinpoint leak locations in minutes

Data delivered immediately

  • Customer owns and always has access to all data
  • Data securely stored on the analyzer and in the cloud for immediate availability.
  • Electronic data facilitates compliance reporting and digital workflow
  • System communicates using 4G wireless technology
  • Data exportable to Geographic Information Systems (GIS)



Simple to use

  • Intuitive and easy to use user interface
  • Rich graphical display shows survey route, survey area, emissions indications and source attributes (i.e. Did emissions originate from a natural gas source?).
  • Records data within two minutes after power on (other methods either require 30-45 minutes to warm up or are over 1000x less sensitive).
  • Digital reports generated automatically in minutes after each survey.



  • Survey local distribution pipelines
  • Survey mains and services
  • Odor investigation
  • Construction verification
  • Post disaster evaluation 
  • Frost line evaluation
  • Survey large public gatherings



The OA-ICOS™ technology advantages

The unique advantages of the patented OA-ICOS technology make ABB’s gas analyzers the preferred choice.

  • Highest Precision and Sensitivity - combines rugged, reliable near-IR diode lasers with an optical cavity to yield measurements with the highest precision and sensitivity in a simple, robust package. Allows to detect leaks from further away and to locate hard-to-find small emissions.
  • Widest Dynamic Range - OA-ICOS provides linear response over a much wider dynamic range than conventional CRDS and TDLAS methods allowing to quantify emissions from small or large leaks.
  • Best Performance - provides unsurpassed overall performance in every important metric (accuracy, speed, linearity, reliability).
  • Field Serviceable / Minimal Downtime - designed for ruggedness and reliability, in addition to performance. Overall simplicity allows easy service, if necessary.
  • Better Value - analyzer performance unaffected by minor shifts in optical alignment enabling the use of simpler components and sub-systems.
  • Comprehensive Platform - ABB uniquely provides a comprehensive platform of solutions based on OA-ICOS technology designed to address any leak detection application.
