The "GCTR SERIES" allows for the control of the oxygen concentration in nitrogen gas to a specified level by injecting compressed air into the nitrogen gas. By monitoring the oxygen concentration after mixing and automatically controlling the amount of compressed air injected, it maintains the set oxygen concentration. For example, it is a highly effective device when supplying a constant concentration of oxygen gas using nitrogen gas generators that cannot set residual oxygen concentration values. It has a proven track record in oxidation reactions during material manufacturing processes, experiments in low oxygen concentration environments, and culturing, among others. 【Features】 ■ Automatic concentration control to maintain the set oxygen concentration even with fluctuations in usage ■ Contact signal output during operation ■ Alarm display for upper and lower limit values of the set oxygen concentration ■ Remote operation possible via external contact signal input *For more details, please refer to the related links or feel free to contact us.
