How to choose the suitable model for the air leakage tester LCD screen?

News 2025-09-02

I. Introduction of air leakage tester equipment


In the field of modern industrial manufacturing, product quality and reliability are the cornerstones of enterprise survival and development. As one of the key indicators for measuring product quality, air tightness is crucial to its accuracy and efficiency.

For example, in the petroleum, chemical, natural gas and other industries, Differential pressure air tightness testers can accurately detect whether these equipment has leakage, avoid serious safety accidents such as fire, explosion, poisoning caused by medium leakage, and ensure the production safety of the factory and the safety of personnel.

In homes and commercial places, regular inspections of the gas system through air leakage testers can timely detect leakage problems in pipeline interfaces, valves and other parts to ensure the safety of gas use.

In the automobile production process, Air tightness tester can be used to detect whether there are leaks in the engine cylinder, fuel system, and brake system, such as detecting the sealing of the engine cylinder to ensure the engine’s power performance and fuel economy; detecting the leakage of the brake system to ensure the reliability of automobile braking.

In the production process of electronic equipment such as mobile phones and computers, air leakage testers can detect the sealing performance of electronic equipment housings, interfaces and other parts to ensure that the products meet quality standards.

  4. electronic fuel pump, vane pump, gear pump, brake booster, intake manifold, exhaust manifold, oxygen sensor, headlight
  5. Gas appliances: stove components and accessories, bellows, pressure regulating valve, plug valve.
  6. Electrical products: sealed relays, sealed motors, submersible pumps, hard disks, etc.
  7. Hydraulic and pneumatic components: solenoid valves, cylinders, filters, various water valves
  8. Others: medical equipment parts, watches, underwater cameras, food packaging
  9. Choose the most cost-effective Screen as the first choice 
  10. 4. Priority will be given to LCD screen brands with high public recognition, guaranteed quality and considerate after-sales service; for example, BOE, AUO, Innolux, Tianma, Kyocera, etc.

III. Analyze the screen requirements and supporting parameters of air leakage test instruments

1. The LCD Panel is clear and visible; and the body is light and compact, easy to carry and test(The size of LCD Panel is generally around 3.5”/4.3”/5.6”/7.0”, and the resolution is between 320*240/480*272/640*480/800*480)

2. The application scenario is industrial indoor scene(The brightness is generally 300nits+, and the operating temperature in industrial scenarios is generally -20 ~ 70 °C)

3. Prioritize the most cost-effective Screen (lowest cost)

4. Priority is given to LCD screens with high public recognition, guaranteed quality and good after-sales service; for example, BOE, AUO, Innolux, Tianma, Kyocera, etc. (Among these brands, Innolux and Tianma are more suitable, while AUO and Kyocera brands are more suitable for mid-to-high-end people)
