The H520 is a special feature of the ATEQ leak detector series and is one of the most precise hydrogen leak detectors available.
Hydrogen, as a leak detection agent, penetrates even the smallest gaps, enabling one of the most sensitive detections possible. A test mixture below a concentration of 5% ensures safe operation.
This technology is the most cost-effective solution if you want to identify leaks in gr/year or ppm units. The H520 makes it possible and easy to automate leak detection and integration.
Typical and common applications are found in the automotive industry and household appliances: cooling systems, light alloy wheels, compressors, air conditioning systems, etc.
Key features:


| Measuring range | Accuracy | Maximum resolution | Saturation |
| 0–100 ppm | The measured concentration is 10% ±1 ppm. | 0.1 ppm | 1000 parts per million |
