III. How to find the right oneAirtightness TesterBranded suppliers?

optionalAir tightness testerYou can't start with the brand, but with the needs. These fundamental issues determine the technological path:

1️⃣ Define testing needs and product characteristics

Define first:

• Test object size range
• Minimum leakage limits required
• Whether in-line production line integration is required
• IP Water Resistant(e.g. IP66/IP67/IP68)
• Required detection principle(positive/negative/volume/flow/differential/helium detection)

Define the basic types of leak detectors and technical routes according to the objectives.

---

2️⃣ Comparative testing principle coverage

Different product structure and testing needs correspond to different testing principles, choose the right principle is more important than choosing the right brand:

Detection Principle	Working mechanisms	Applicable Scenarios	Precision Characteristics
positive pressure	Fill the measured part with compressed gas and monitor the change in pressure drop.	Products with access cavities	Medium precision, low cost
suction	Vacuuming of the measured part and monitoring of pressure changes	Vacuumable closed products	Medium precision, suitable for open structure
volumetric method	Extrapolation of leakage from volume changes	Fully enclosed rigid structure	Highly accurate and temperature independent
flow rate method	Direct measurement of leakage gas flow	Continuous testing of large-scale production lines	High accuracy and speed
differential pressure	Comparison of the pressure difference between the standard and the measured part	Products with extremely high sealing requirements	Extremely high accuracy and repeatability
helium mass spectrometry	Utilization of helium as a tracer gas	Very small leakage and high end precision verification	Ultimate precision at the highest cost

Selection Recommendations: Prioritize suppliers that can cover a wide range of detection principles, which will avoid the dilemma of having to replace the whole set of equipment when upgrading the product in the future.

---

3️⃣ Focus on automation and data traceability

• Support for MES/PLC/Robot Integration
• Ability to automatically categorize and generate reports
• Availability of product traceability(Barcode/QR code)

This is related to the efficiency of the production line and the level of quality management.

---

4️⃣ Emphasis on after-sales response and local service

For mass production companies:

• response time
• On-site commissioning and engineering support
• Spare parts supply

are often more important than equipment parameters. This is why many companies choosePrecision EngineeringThis is because of the faster local after-sales response time.

---

5️⃣ Refer to industry case studies and user feedback

• Experience with customers in the same industry
• Certified or not(CE, ISO, etc.)
• Availability of successful on-the-ground programs

All of this contributes toReduce selection riskThe
