7001

• Solid-Liquid-Gas Analysers and Monitors

Gas Analyser For Turbine Generators, Model 7001 is a rugged, portable, easy-to-use gas analyser that monitors purge gases and the cooling gas in hydrogen-cooled turbine generators. It measures hydrogen in CO2 and air in CO2 as well as air in CO2 during maintenance purging of hydrogen rooted turbine generators. Switch selectable ranges on the instrument make it easy to choose the measurement required. The sensor works on thermal conductivity principle.

• Portable, rugged, lightweight, sealed reference cell
• No need for a flowing reference support gas
• Uses no consumables and is virtually maintenance free
• Proven thermal conductivity detector
• Switch-selectable gas for easy choice of desired measurement
• Large, easy to read readout for observing rate of change (trending) of purge gas mixtures
• No installation required
• Minimizes costly maintenance downtime
• Saves money by avoiding needless waste of CO2 purge gas, and
• Assures optimum efficiency by detecting air contamination
