The Agilent HLD BD30 Dry 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 HLD BD30 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 or bench, and includes an oil-free Agilent TriScroll 620 Dry Scroll Pump, with a pumping speed of 30 m3/hour, for very rapid evacuation of test parts and systems and rapid clean-up of ambient helium between test cycles. Hardware required to connect the TriScroll 620 to the HLD BD30 is also included.
