Brooks 2500 Series Acrylic Tube Variable Area Flow Meters

Brooks 2500 Series Acrylic Tube Variable Area Flow Meters

Constructed from precision-machined acrylic, 2500 Series flow meters use annealed, unibody construction that eliminates the leaks and panel detachment common with non-annealed, moulded designs. An easy-to-read scale, rod-guided float and positive-stop valve ensure performance and safety. Choose from several valve, fitting, O-ring and float options to fit your specific project.‚Äč
