• Whether or not you use water or not, you can quickly vacuum the packaging to easily check the sealing ability of the test sample and whether or not there are any scratches. • If you use water, you can visually check the packaging defects by using air bubbles. • Accurate pressure adjustment is possible. Once the valve is adjusted, the values are the same and repeated testing is possible. • Lamp display allows you to visually check the operating status of the tester. • You can connect the tester to a commercially available or hand-held vacuum pump and start the test. • You can set the test time using a timer, perform repeated testing, and use a vacuum meter to indicate the correct pressure.
