The Servomex SERVOPRO FID is a Flame Ionization Detector based analyzer designed and optimized for quality control in pure oxygen, nitrogen, hydrogen, argon, helium, air or carbon dioxide. It delivers reliable, accurate and low-noise measurements of total hydrocarbons, ensuring gas stream inflammability levels are closely monitored. If a problem is the detected, an integrated automatic fuel shut-off valve function ensures if the flame is extinguished and the fuel feed lines are automatically closed.
