Adixen’s new ASH 2000 hydrogen leak detectors available from John Morris Scientific are helping various industrial segments identify extremely small leaks caused by material defects or errors during production.  

Adixen’s ASH 2000 hydrogen leak detectors can be combined with a bottle of tracer gas in an inexpensive standard mix of 95% nitrogen and 5% hydrogen, and a device to inject the tracer gas into the product being tested to pinpoint the exact position of leaks quickly and easily.  

Miniscule leaks caused by material defects or errors in the manufacturing process result in significant and costly problems in industrial production. Adixen’s new ASH 2000 detects leaks as small as 1 · 10-7 mbar · l/s.  

The compact and portable ASH 2000 hydrogen leak detectors are also available in a battery operated version.  

Equipped for both data communication and manual control of inputs and outputs, the ASH 2000 facilitates automatic leak testing. Using available standards (reference leaks or calibration gas), the ASH 2000 can be easily calibrated to make automatic accept/reject decisions.  

Using diluted hydrogen in the tracer gas mix offers the user reliable detection, user-friendly technology, low costs and minimal servicing requirements.

Automotive application benefits of the ASH 2000 hydrogen leak detectors include simple leak detection without use of fluids, offering higher sensitivity than pressure decay measurement.

The automated test method is unaffected by temperature variations and also offers NIST traceability and accurate leak size measurements.

Benefits of the hydrogen leak detectors in aerospace applications include reduced test time compared to methods involving the use of compressed air or soap sprays as well as offering a clean and dry process.

In addition to pin-pointing the exact location of invisible leaks, the testing method also uses inexpensive tracer gas and a complete system for gas injection.

The ASH 2000 offers several benefits in medical applications and is a suitable solution for testing of items such as implants, blood pumps, fluid bags, catheters and various consumables.

The test method is completely dry and the tracer gas does not affect the material being tested. The ASH 2000 can also provide the exact location of the detected leak, and is not impacted by elastromeric creep.

The ASH 2000 hydrogen leak detectors offer a completely dry test method for packaging applications, suitable for flexible or hard packaging materials.

The ASH 2000 can be used to detect leaks in small and large batches in the manufacturing industry. The leak detectors are ideal for testing products such as plastic containers, hoses, valves and hydraulic components for leak detection.

The ASH 2000 offers a faster and more reliable method than bubble testing for tightness control and leak detection in process applications.

RAC application benefits include inexpensive tracer gas and improved cost-efficiency compared to helium-based leak detection in addition to maintenance-free test equipment and <0.5 g/y equivalent refrigerated sensitivity.

Additional benefits include zero risk of measurement becoming clogged while cloud hunting is also eliminated, reducing the risk of the detector being ‘blinded’ by background gas.
