Working Principle of Glove Integrity Tester

The glove integrity tester is a device designed to evaluate the integrity of sleeves, gloves or one-piece gloves in isolator/RABS systems. Its core working principle relies on positive pressure testing and accurate measurement of pressure drop values.

Before starting the test, the operator connects the test port of the tester to the operating port of the isolator to ensure that the tester is in close contact with the glove or sleeve to be tested. After that, the tester works in a positive pressure mode, that is, applying a constant gas pressure to the inside of the glove or sleeve.

Once the gas enters the inside of the glove or sleeve, the glove integrity tester's precision sensor begins to monitor the pressure drop value, that is, the rate of pressure loss when the gas passes through these protective equipment. If the glove or sleeve remains intact, the pressure drop value is usually maintained within a preset reasonable range.

The test results are intuitively displayed on the glove integrity tester's control panel in the form of a pressure drop value. The operator can refer to the preset value range to easily judge the integrity of the glove or sleeve. If the pressure drop value is abnormal, such as exceeding the preset threshold, it may mean that the glove or sleeve is leaking or damaged, and needs to be repaired or replaced in time.
