How Air Leak Testing Works

The air leak testing machine uses pressure-based detection methods to evaluate 

the sealing performance of a product. The test object is pressurized, and 

any pressure drop or leakage rate is measured to determine if the product 

meets quality standards.

Operation Video

Ideal for leak testing of sealed housings, valves, reservoirs, connectors, medical consumables,

 and consumer electronics enclosures.

Precision Air Leak Testing Machine (2 Stations)

High-accuracy pressure decay leak testing for sealed parts. Designed for stable, repeatable

results in mass production with automated judgement and traceability options.

Key Benefits

• 2 stations to boost throughput for production lines

• 0.1 Pa resolution; sensor accuracy up to 0.05% FS

• Wide pressure range: -20 kPa to 500 kPa

• Automatic PASS/FAIL judgement with sound & light alarm

• Barcode/QR code scanning for traceability (optional data export)

Specification

Typical Applications

• Automotive components (valves, housings, fuel systems)

• Medical devices (filters, tubing, sealed containers)

• Electronic products (battery housings, connectors)

• Packaging and sealed containers

• Industrial plastic components

Test Principle & Process

Inflation → Stabilization → Detection → Automatic Judgement. Parameters (test pressure, 

stabilization time,detection time) are configurable based on part volume and target leak rate.
