The DustMark Lifter is a convenient, portable method for lifting dust marks from nearly any surface. It works by generating a static electrical charge which is passed through a special metallic lifting film. Dust from footwear and tire impressions is attracted to the black underside of the film. Three metal studs on the underside of the unit act as grounding points to bridge the film to the included metal grounding plate. The amount of current generated can be controlled via a dial on the front of the unit. Unique circuitry automatically deactivates the unit when not in contact with the grounding plate. The kit includes the DustMark Lifter, roll of lifting film, grounding plate and a convenient carrying case. The unit weighs .3 kg 10.8 oz. and measures 12.5cm x 6.7cm x 3.2cm 5" x 2.5" x 11⁄2".
