Designed for fast, accurate leak detection, the ELD500 precision leak detector is customizable for any application. Users can benefit from simple pass/fail readings through to detailed analysis via the easy-to-read control interface. Due to the low weight and integrated carry handles, it is mobile enough to be benchtop or trolley-mounted. The leak detector can be set to work in either vacuum mode for precise measurement of leak rate or sniffer mode for identifying the leak location. The unit achieves excellent repeatable accuracy through calibration with the integrated test leak source and high-quality mass spectrometer, so it could be used on a production line, where consistent measurement repeatability is critical, or in a laboratory environment, where the measurement of extremely low leak rates is typically needed.
