Differential Pressure Helium Leak Detector VH90B

Features :

  • Modular Integrated design.
  • Automatic evacuation pressure and time setting, high leak detection efficiency.
  • It is suitable for direct pressure and flow rate leakage detection methods, and compatible with the use of single and multi-station requirements, to achieve one device to detect multiple products.
  • Wireless remote-control function (optional).
