LR-230   Air tightness leak detector


LR-230 series air-tightness detectoradopts the principle of direct pressure and uses air as the medium to pick up the leakage of the product. It is a non-destructive testing instrument.The working principle is to inflate the test product to the specified air pressure, then close the valve, after a period of stability, measure the change of air pressure during the test period, calculate the leakage through conversion.With its high precision and complete function, this instrument is widely used in sealing testing of open products or parts of closed products.
