HLD PD03 Portable Dry Helium Leak Detector

The Agilent HLD PD03 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 compact, multi-use HLD PD03 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 an oil-free scroll/diaphragm combination pump, with a pumping speed of 3 m3/hour, which eliminates any risk of oil contamination of test parts or systems.


  • Six different application set up guides helps you correctly configure your instrument for the best performance, ensuring that parameters are properly set for a thorough and efficient test.
  • Larger, more durable, more responsive touch screen interface rotates 180° for ideal viewing.
  • Cleaner, more intuitive user interface. Immediate access to often used features and a flat menu structure allows you to quickly find the setting you need.
  • Startup wizard helps user set up the instrument on first-time power up.
  • Enhanced charting capabilities: Zoom for closer inspection of data, color-coded set points, time-based plot records leak rate and pressure.
  • A large work surface provides plenty of room for parts to be tested, tools, etc.
  • Improved power-off process keeps spectrometer under vacuum and protects the turbomolecular pump.
  • Dry vacuum pump eliminates the risk of oil contamination of test parts and systems.
