The Agilent HLD MR15 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. This detector 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. Integrated wheels enable easy relocation.The MR15 includes an Agilent DS-302 Rotary Vane Pump, with a pumping speed of 15 m3/hour, for rapid evacuation of test parts and systems and rapid clean-up of ambient helium between test cycles.
