PHD-4 is controlled by an advanced microprocessor that allows superb simplicity of operation. PHD-4 is sensitive to helium concentrations enabling it to distinguish even the smallest drips in objects that contain a small helium or air pressure inside. The sensitivity of the PHD-4 depends on the SIPD or Selective Ion Pump Detection technology which is privately-owned by Agilent. The display of the PHD-4 can be programmed to use either English, French, German or Italian language. Including the battery, PHD-4 weighs 2.6 kg and can either replace or be used together with the bubble test, pressure decay, or any existing methods.
