The table below summarizes many of these capabilities (note: many analyzers can be used for more than one gas). Please contact us for any questions or assistance in configuring a system.

Specific product formats include:
  • Drone: ABB's newest line of gas analyzers that are configured for mounting on a drone with an emphasis on lightweight products that deliver the sensitivity needed for most applications.
  • Portable: ICOS gas analyzers designed for use in most field operations. These systems can typically be carried and are suitable for operation under battery power.
  • Laboratory/Stationary: Gas analyzers suitable for use with most indoor applications.
  • Deep Water: Specialized analyzers configured for use at very high pressures under water. Typically operational to depths of up to 2500 m.
  • Concentration: Gas analyzers designed to deliver information on the concentration of this gas.
  • Isotopes: Analyzers configured to deliver the relative abundance of different isotopes of the molecule(s) being measured.
