Sensirion’s SFC5500 mass flow controllers are one of the first mass flow controllers available in distribution globally. Mass flow controllers are a super easy and very precise way to control the flow of gases. They are widely used in medical, industrial, and research applications, both in automation and as crucial components of larger instruments. Sensirion’s SFC5500 revolutionary mass flow controllers are based on the microthermal measurement principle and the patented microthermal CMOSens Technology. Each SFC5500 is calibrated for multiple gases which can be selected by the user, and their fittings are exchangeable. The SFC5500 comes in several versions for controlling different gas flow rates. To select the correct version, please check the datasheet.
