HLD PR02 Portable Helium Leak Detector

The Agilent HLD PR02 Leak Detector uses a mass spectrometer tuned to detect helium, which is used as a tracer gas to locate and/or measure very small leaks in enclosed devices or systems. The compact and portable HLD PR02 is both a precise instrument and a robust workhorse, featuring an easy-to-use touch screen interface and menu structure that quickly connect users to powerful leak detection capabilities. Built-in application setups shorten test cycles, and setups can be saved to assure repeatability. It fits easily on a table, bench, or cart. The enclosed primary vacuum pump is the Agilent DS 40M rotary vane pump, with a pumping speed of 2 m3/hour.
