Edwards ELD500 WET is a mobile helium leak detector with an integrated oil sealed rotary vane pump.
Ready to go in under 2 minutes, the ELD500 WET is a portable leak detector designed for fast accurate leak detection in a wide range of applications. It has an easy to use control interface with a large clear graphical display. It can quickly and easily be set up to work in either vacuum mode for precise measurement of leak rate or in sniffer mode for identifying leak location.
