    IT is a meter which measures pressure difference - how much pressure is lost due to leakages in a system. Here is a link to Dwyer who manufacture the gauge. Series 2000 | Magnehelic® Differential Pressure Gage | Dwyer Instruments

    The work is to put together a system which generates a known pressure at a known flow rate. These instruments are commonly used in the repair of clarinets, flutes and other such whistles.

    The old Bandstand Test....pull the slide, depress valve with finger over the open tube end, blow thru horn and listen/feel for leakage past the valve.

    Both Votaw Tools and MusicMedic have leak detectors using the Magnehelic Gauge, prices start around $415. I am savind up for one if the N+1 does not get in first.

    Regards, Stuart.
