Over the years, Dwyer Instruments, Inc. has continuously improved its position as a global leader in designing and manufacturing innovative controls, sensors and instrumentation solutions. This success is due in part to our invention of the Magnehelic® differential pressure gage in 1953. Since then, the market leading Magnehelic® differential pressure gage has been continuously updated and improved. The Magnehelic® gage is a versatile low differential pressure gage which quickly indicates air or noncorrosive gas pressures – either positive, negative (vacuum) or differential. Over the years, among countless other updates, we’ve invented a high accuracy version of the Magnehelic® gage which provides an accuracy within 1% of full scale and created backwards compatible products.
