The electrostatic extractor uses high voltage to recover footprints, as evidence and as a whole for on-site investigation.
Technical Principle: Using the electrostatic charge extracted from the membrane to attract dust particles on the surface of the object. In order to attract dust to the maximum extent, it is necessary to use grounding leads or grounding panels. In this way, the voltage between the extracting film and the object transferring dust can be maximized. By placing the grounding lead in the use position, the grounding effect can be optimized.
