7. Positive & Negative Pressure Air Leak Tester

Why do some products have to measure the negative pressure after measuring the positive pressure? Precision Industrial Technology tells you the truth!

This paper introduces the importance of positive and negative pressure airtightness testing. Positive and negative pressure test can complement the detection of sealing defects of products in different working conditions, simulate the real use of the environment, enhance the stability of waterproof grade, reduce the false detection rate. Precision Engineering JC-HH100 positive and negative pressure airtightness instrument with positive and negative pressure two kinds of ability to support the pressure drop and leakage rate of two kinds of determination, can simulate the real use of the scene, applicable to R & D verification, mass production sampling or full inspection, reduce enterprise costs.
