GRMF Series Air Flow Meters and Controllers
GRMF Meters are economically versatile, user friendly devices. Mass flow is read directly for a wide range of flow rates and gases. They feature on-board backlit display and on-board set point control knob. Standard power is 24VDC supplied by an AC adapter. Their durability and NIST-traceable calibration accuracy, coupled with their relatively low cost, makes them ideal for OEM applications. Call 1-888-FATHOMS (328-4667) for more information.
