3-0-3 INCHES OF WATER/7.5-0-7.5 cm of water Magnehelic Gauge & Mouthpiece Adapter Assy

The Dwyer Magnehelic Gauges have been the standard in the SCUBA diving industry for years. We recommend using the dual scale 3-0-3 inch of water/7.5-0-7.5 cm of water gauge for checking 'cracking' effort. The expanded scale covers all industry second stage regulator 'cracking' effort specifications and provides much more accurate and consistent readings.
