  The SFC5500 is now available via distributors worldwide
  
  High performance off the shelf - the new SFC5500 mass flow controller series. The high-performance mass flow controller is calibrated for multiple gasses and comes with push-in fittings, which can be changed easily by the user. Thanks to the SFC5500's ultra-wide control range, each device can cover multiple flow ranges found in conventional devices. As a result, only three different versions with different flow ranges are enough to cover most flow rates of interest. This makes the SFC5500 ideally suited for applications in the medical, analytical and industrial sectors.
