GR Series

GR Meters are economically versatile, user friendly devices. Mass flow is read directly for a wide range of flow rates and gases. Available as a meter or controller, 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.
