Having trouble with invisible leaks in your system that affect product quality? Leak Tester or leak testing equipment is a crucial component in performing Leak Test to prevent potential damage to the workpiece. The engineering team from SCMA is ready to provide solutions for Air Leak Tester, including complete industrial level measuring instruments. Reading this article will help you understand the working principles and accurately select the right tool for your job requirements.
What is a Leak Tester?
A Leak Tester or leak testing equipment is used to detect gas or liquid leaks from a workpiece or closed system, such as packaging, tanks, and piping systems, to evaluate whether the leakage value is within the specified limit.
How a Leak Tester Works
Air Leak Tester using pressure drop measurement will supply air into the workpiece and isolate the source. After the pressure stabilizes, the device will measure the change within a specified time period to compare with the standard. This method evaluates overall leakage and does not directly indicate the location of the leak. See details at Leak Testing Theory
How many types of Leak Testers are there?
Performing Leak Test can be categorized according to the main testing method to suit the type of product. SCMA has classified the testing equipment for safety in the industry as follows:
Portable type
This type of equipment is a compact tool designed for easy portability. It is suitable for technicians who need to take it to remote locations to perform Leak Test quickly. It meets the needs of high mobility inspection tasks in limited spaces.
Desktop / Fixed type
The desktop type testing equipment is designed for use in laboratories or production lines in industrial factories. This group of equipment supports continuous Leak Test with high accuracy. It is suitable for inspecting the safety of medical devices or components that require precision.
Maintenance of Leak Tester
Proper maintenance of the equipment is very important for the accuracy of Leak Test. The preventive maintenance guidelines from the SCMA engineering team experience are detailed as follows:
Inspect air hoses, connectors, and seals
Inspect air hoses, connectors, seals, and fixtures for any damage or wear. Leaks in the test set itself can cause inaccurate results. Therefore, it should be checked using reference parts or equipment according to the specified method.
Air system maintenance
For Air Leak Tester equipment, regularly maintaining the air filter set or Air Preparation Unit is essential. It is necessary to clean dust and oil residue in the hose before installation, and replace the filter immediately when performance decreases to prevent moisture from entering the system.
Turning the device on and off
After completing the Leak Test, a Dust Plug should be used to close the device connection port every time it is removed from the system. This step helps prevent dust and contaminants from entering and clogging the sensor, helping to extend the lifespan of the measuring instrument.
Tools for Leak Detection and Related Testing
Tools from SCMA Co., Ltd. offer various types of tools. It is important to classify the testing tasks, such as pressure tightness testing, gas concentration testing, refrigerant leak detection, and leakage current measurement before selecting the appropriate tool.
1. Leakage Current Tester
This device is used to test and measure leakage current that may escape from electrical appliances to prevent electric shock hazards. Leakage Current Tester is used to check electrical safety according to the methods and requirements of each type of equipment. This task is separate from gas or liquid leak testing.
2. Gas Leak Detector
A gas detector is used to detect the presence or concentration of target gases in the environment, such as carbon monoxide or methane. On the other hand, an Air Leak Tester is used to test the tightness of parts or air-sealed systems, so they answer different questions.
3. Refrigerant Leak Detector
A specialized device used to detect refrigerant leaks in air conditioning systems or cold rooms. Refrigerant Leak Detector can quickly locate leaks in R-134a refrigerant groups, helping to reduce refrigerant and energy loss when leaks are found and repaired.
Advantages of Leak Tester
Tools from SCMA stand out in terms of performance, safety, and coverage ranging from gas detection to Air Leak Tester. The main advantages of choosing industry-standard tools are as follows
Safe and Easy to Use
Using fixtures that are suitable for the workpiece make testing convenient and repeatable. You should check the pressure coordinates of the device, workpiece, and fixture, and follow the manufacturer's instructions
High Accuracy
The selected Air Leak Tester that has an appropriate measurement range and set conditions for the workpiece can detect small leaks. The results from pressure drop measurements help assess overall leakage, while identifying the location of leaks may require additional methods
Versatile Usage
Various types of equipment are available to comprehensively support specialized tasks. Whether it is detecting hazardous gases, finding leaks in cooling systems, or performing Leak Test, it can be adapted flexibly to the factory environment
Professional Care
Purchasing equipment from a specialized dealer provides full technical support. The SCMA engineering team is ready to assist from selecting the appropriate Air Leak Tester specifications for the job site, along with service after-sales that help you feel assured in the long term
How to Purchase Leak Tester
Selecting a Leak Tester should consider the usage characteristics for maximum value. Insights from experts to help you choose Air Leak Tester or Leak Test equipment are as follows
- Consider the system to be tested: Choose between compressed air, refrigerant, or electrical systems to match the sensor precisely
- Check pressure coordinates: Select a testing device, workpiece, and fixture that support pressure according to the testing method, and check the resolution and leakage rate criteria that need to be distinguishable
- Select a tool format suitable for the job: Portable models are suitable for field maintenance, while desktop models are suitable for continuous Leak Test
- Assess after-sales service: You should choose a dealer with an engineering team for consultation and in-country calibration service
Industries That Require Leak Testers
Performing Leak Test is an essential process in many sectors to confirm product quality and safety. Using Leak Tester or Air Leak Tester plays an important role in the following industries:
- Automotive Industry: Used to test braking systems, fuel systems, and radiators for maximum driving safety
- Electronics Industry: Detect leaks in housings or sealed components according to product specifications
- Food Packaging Industry: Use Air Leak Tester to check the integrity of seals and prevent contamination
- Refrigerator Air Conditioning Systems: Detect refrigerant leaks to maintain cooling efficiency
