Integrity tester is an important equipment used to detect the integrity and sealing of various items such as gloves, filters, filters, etc. It is widely used in multiple fields such as pharmaceuticals, healthcare, food processing, biotechnology, etc. to ensure product quality and safety. The following is a detailed analysis of the integrity tester:


1、 Working principle


The working principle of an integrity tester is usually based on the pressure testing method. Taking the glove integrity tester as an example, it operates based on the principle of air pressure. During the testing process, the gloves are placed in the testing chamber of the detector and a certain gas pressure is applied to the inside of the gloves through the control system. If the gloves are damaged or have holes, gas will leak out of the gloves, causing a decrease in pressure inside the testing chamber. The high-precision pressure sensor equipped with the detector will monitor the pressure changes in the testing chamber in real time. When the pressure drops to a certain level, the sensor will send a signal to indicate that there is an integrity issue with the gloves.


2、 Testing function


The integrity tester has multiple testing functions, including but not limited to:


Bubble point test: By injecting gas into the tested object and observing whether bubbles are generated, its integrity is determined. This method is commonly used for integrity testing of filter cartridges and filters.


Pressure holding test: After applying a certain pressure, observe for a period of time whether the pressure is stable to evaluate the sealing performance of the tested item.


Diffusion flow test: measures the diffusion flow rate of gas through the tested object to evaluate its filtration efficiency and integrity.


Water intrusion test: By simulating water intrusion into the environment, the waterproof performance of the tested item can be evaluated by checking whether it can effectively prevent water infiltration.


3、 Application Fields


Integrity testers play an important role in multiple fields:


Pharmaceutical industry: used to detect the integrity of filters and ensure that sterile drugs are not contaminated by microorganisms during the production process.


Medical industry: Testing the integrity of personal protective equipment such as surgical gloves and protective clothing to ensure the safety of medical staff.


Food processing: Testing the sealing of food packaging materials to prevent contamination of food during storage and transportation.


Biotechnology: Testing the integrity of experimental equipment in laboratory environments to ensure the accuracy and reliability of experimental results.


4、 Characteristics and advantages


High precision: By using high-precision pressure sensors and advanced control systems, accurate and reliable detection results can be provided.


Automated operation: Implementing automated operations, saving human resources, and improving work efficiency.


Data recording and report generation: capable of recording the data and results of each test, and generating detailed inspection reports for subsequent analysis and tracking.


Portability: Some devices are compact in size, making them easy to carry and move, and suitable for testing needs in different situations.


5、 Precautions for use


Before use, carefully read the device's user manual to understand the operating methods and precautions of the device.


During the testing process, it is important to ensure that the tested item is properly connected to the equipment to avoid inaccurate test results caused by improper connections.


After use, the equipment should be cleaned and maintained in a timely manner to maintain its good working condition.


Integrity tester is a powerful and widely used detection device. It provides important quality assurance measures for multiple fields such as pharmaceuticals, healthcare, and food processing through precise stress testing and data analysis.
