Helium leak detector

Adixen’s general-purpose helium leak detector, the ASM 310, can find leaks as small as 5 x 10^-13 Pa m³/s in vacuum test mode. The unit is semi-portable, weighs only 21 kg and features an oil-free vacuum system.

The detector features a colour touch screen with easy parameter settings and has multiple read-out and protocol functions, such as graphical leak signal and trend indication. The test data can either be stored onto SD memory cards or recorded by using the free software, ASM View. A vacuum diagram shows the status of all major components, such as vacuum pumps, valves and the analyser cell.

The detector uses a contact-free operating diaphragm pump to back its molecular drag pump. The low rotational speed of the included turbo molecular pump protects the unit from accidental air inrush and allows the leak detector to be moved during testing.

Due to the dry vacuum system and low rotational speed, the leak detector requires very little maintenance. Adixen ASM 310 has two filaments built into the analyser cell as standard, ensuring uninterrupted operation if one breaks. The typical lifetime claimed for the filaments is three years. Filament replacements can be performed in the field without the need for special tools.
