  **Q/GDW stands for “Corporation standard of State Grid Corporation of China”.

Features:

  Industry-leading sensitivity:Sensitivity equal to or better than 10pC.
  Robust to interferences:Complete suite of interference reducing technologies: Spectrum analysis, frequency-selective filtering, interference separation, and comprehensive shielding.
  Diagnosis and analysis:Full range of analysis assisting graphical interfaces: PR, PRPD, PRPS, Correlation, and Selecting/masking windowing.Built-in interference and discharge patterns for automated signal classification.
  Accurate localization:3D modeling technology ensures a higher localization accuracy.
  Synchronization:Wired or wireless synchronization.
  Sensor variety:We carry AE sensors of various frequency bands made by PAC for different test objects.
  Rigid sensors:Specifically designed sensor protectors can protect the sensors from being damaged.
  Easy operation:The lightweight and compact hand-held device can also be used with lanyard or tripod.Sensors can be mounted in different ways: magnets, suction cups, and straps.For hard-to-reach positions and in-service surveying operations, we provide insulated rods, sensor extension rods, and disk antennas for convenient and quick operations.
  Long battery life:Each removable lithium battery provides more than 8 hours of continuous working time.
  Designed for field use:The touch screen display is readable even under direct sunlight, suitable for field use.
