Instrument for testing water impact penetration

 Originally this guideline was developed to predict for rain penetration. It has now been adopted by the medical industry. The Impact Penetration Tester features a number of attributes deigned to ensure accurate testing including a small blade inside the funnel to allow water to move smoothly through the funnel without any swirling motion, strong clamps to hold the sample firmly in place, a weighted bottom clamp to hold the sample flat and an integrated drip catcher to catch any leftover water from the previous test. An air-bubble on the base shows when the instrument is properly leveled.
