Airtightness testing equipment (also called sealing tester or leak detector) is a special equipment used to detect the sealing performance of products or packages. It is widely used in automobile, medical, electronics, home appliances, packaging and other industries. Its core features are as follows:
---
1. High precision and high sensitivity
- Can detect extremely small leaks (such as gas leakage rate as low as 0.001 cc/min).
- Use high-precision sensors (such as pressure sensors, flow sensors) and algorithms to ensure reliable test results.
---
2. Multiple detection principles
- Pressure decay method: Determine leakage by monitoring pressure changes after inflation.
- Vacuum decay method: Detect pressure recovery after vacuuming.
- Flow detection method: Directly measure gas flow.
- Helium mass spectrometer leak detection (high-precision scenario): Use helium as a tracer gas to detect small leaks.

3. Automation and intelligence
- Integrate PLC or industrial control system to support automated testing processes.
- With data storage and analysis functions, it can generate reports and upload them to the Internet (in line with the needs of Industry 4.0).
- Some equipment is equipped with AI algorithms to adaptively adjust test parameters.
---
4. Wide applicability
- It can adapt to workpieces of different sizes and shapes (such as battery packs, medical devices, bottle caps, pipes, etc.).
- Provide customized fixtures or adapter interfaces to meet diverse needs.
---
5. Efficient and fast
- Short detection cycle (usually a few seconds to a few minutes), suitable for online detection of production lines.
- Multi-channel design (simultaneous detection of multiple workpieces) to improve efficiency.
---
6. User-friendliness
- Touch screen operation interface, easy parameter setting.
- With sound and light alarm function, it can quickly prompt unqualified products.
- Support multiple languages and standardized interfaces (such as RS485, Ethernet).
---
7. Reliability and stability
- Anti-interference design (such as temperature compensation, vibration isolation), adaptable to industrial environments.
- Key components (such as air circuits and sensors) are made of durable materials and have a long life.
---
8. Safety and compliance
- Comply with industry standards (such as ISO 13485 for medical devices and ISO 9001 for the automotive industry).
- Explosion-proof design (suitable for flammable and explosive environments).
---
9. Environmental protection and energy saving
- Some equipment uses oil-free air source to avoid contamination of the tested parts.
- Low power consumption design to reduce energy waste.
---
10. Data traceability
- Record test time, serial number, results, etc., support QR code/RFID binding, and facilitate quality traceability.
---
Typical application scenarios
- Automotive industry: Detect the sealing of engine cylinders, fuel tanks, and headlights.
- Medical field: Air tightness of syringes, infusion bags, and breathing masks.
- Electronic appliances: Waterproof mobile phones, smart watches, and battery casings.
- Packaging industry: Leakage detection of food and pharmaceutical packaging.
