Highly transparent organic glass vacuum chamber, touch LCD, microcomputer control. The vacuum leak tester with user management authority can be used for packaging sealing detection of medicines, foods, cosmetics, etc.

The vacuum decay leak tester adopts positive pressure and negative pressure test principles for package sealing test. Comes with a touch LCD screen and micro printer, the vacuum decay tester provides a variety of test conditions for the color water method and microbial invasion test. RS232 data interface, pressure setting 0.1-5.0 KPa, and pressure range 0-400.0 KPa (free setting), and 220V 50Hz power supply. The vacuum leak tester can complete vacuum (negative pressure) and pressure (positive pressure) tests, and suitable for sealing tests of medical devices such as pharmaceutical soft packaging, oral liquid bottles, injection bottles, etc.

The vacuum decay leak tester with seven independent test functions adopts the positive pressure principle to test sample sealing, and the touch screen of the leak tester can show the test process curve. The standard test range is 0-1.25MPa, 0-174.2psi, and other test ranges are optional. Equipped with a printer and different fixtures, the leak detector has user management permissions, test accuracy of up to ±1%, gas source interface Ф8mm Polyurethane tube, and a gas source pressure of up to 0.4MPa~0.9MPa. Vacuum leak testers are widely used in quality inspection institutions, medical devices, food, pharmaceuticals, etc.

High-voltage discharge leakage tester, adopting high-voltage discharge test principle and non-destructive testing technology, can detect leakage of tiny pores. Range 0-20ma, test voltage 0-20 kV. The roller electrode is installed inside the detector for automatic detection. The leak tester machine can work at ambient temperature (20°C, 30°C) with a detection sensitivity of 1.0-3.0 um leaks. Double grounding, with error alarm function. The pressure leak detector is suitable for sealing integrity testing of packaging containers such as glass infusion bottles, BFS, eye drop bottles, vials, ampoules, prefilled needles and other pharmaceutical packaging.

The multi-channel leak detector has a 4-channel design to test 4 samples at the same time, which makes the sample data independent, and the test efficiency is higher. The measuring range is 0~400.0KPa, the air source interface is Ф8mm polyurethane tube, and the measuring accuracy is up to ±1%. The data interface of the air pressure leak tester is RS232, which can be connected to the user's LIMS system, 220V 50Hz. The pressure leak detector has an automatic constant-pressure water replenishment function to ensure that the experimental process is carried out under the preset pressure. The leak tester equipment is suitable for overall sealing performance detection and fatigue testing of various medical devices, arm bags, etc.

Air pressure leak tester adopts the positive pressure detection method to test the sealing performance of the component. The air leak tester has high-precision testing functions, data communication, and data storage functions. The air leak detector needs to be equipped with corresponding fixtures according to the sample to be measured. The testing pressure range of the leak detector is optional from 1kpa to 800kpa, and the built-in pressure sensor has a resolution of up to 0.1-200pa, supported by an AC 220V 50Hz power supply.

The digital air leak tester comes with a 3.5-inch touch screen display and adopts a positive pressure test mode to assess the sealing performance of the sample in kPa (other units are optional). The supporting fixture of the air leak tester needs to be customized according to the test sample. The detection pressure range is 1kPa~800kPa, and the resolution of the internal pressure sensor can reach 1~200Pa, with an accuracy of up to 0.25%. The air leak tester machine is mostly used for sealing detection of batteries, automotive parts, smart electronic devices, reagent bottles, etc.
