The ATEQ F520 is a compact air/air leak detector designed for production-line airtightness testing. It measures differential pressure drop between a test part and a reference part after both are filled to the same pressure, providing stable and repeatable leak measurement suited to repetitive manufacturing checks and fixture-based QA.

This particular unit is configured for 6 bar / 600 kPa operation and has an internal power supply, so it powers from a standard IEC C13 mains cable (no external 24V supply required).

Typical applications

• Production-line leak testing of sealed parts and assemblies

• Quality verification on fixtures and workbenches

• Large-leak screening followed by small-leak measurement cycles

Key technical information (manual reference)

• Measurement principle: differential pressure measurement (air/air) between test and reference parts, can be used with a reference, without a references or a central zero.

• Pressure drop ranges: 0–50 Pa / 0–500 Pa / 0–5000 Pa 

• Test modes for sealed components: Large leak mode (large leak only) and Standard mode (large leak then small leak)

• F520 dimensions (depending on case type): 136 x 250 x 180 mm (short) or 136 x 250 x 255 mm (long)

• Weight: approx. 6.5 kg

• Operating temperature: +10°C to +45°C
