GA-150 is a rugged, portable, easy-to-use gas analyzer that monitors purge gases and the cooling gas in hydrogen-cooled turbine generators. It measures hydrogen in air & hydrogen in CO2 as well as CO2 in the air during maintenance purging of hydrogen rooted turbine generators. Switch selectable ranges on the instrument make it easy to choose the measurement required.

To minimize downtime, it is important for the 2 step purge process to proceed quickly and effectively. The GA-150 helps achieve those objectives. During the first stage of maintenance purging, the unit monitors the changing H2/CO2 mixture. This allows operators to know the earliest moment to begin the second stage (air purge). This also saves money by minimizing CO2 usage. During the second stage, the GA-150 monitors air in CO2, which helps you decide when workers can begin maintenance.
