The Spark board is particularly well suited to applications where perforations in plaastic web materials need to be recognized, evaluted or counted. The high voltage test method used is
also extremely well suited to detecting microscopically small holes, for example in corona treatment rollers. The electrical flashover that occurs is displayed on the display unit and at the same
time, a low-voltage electrical impulse is generated, which can, for example, be used to operate an alarm, or feed a counter with the number of tear-off bags that have been produced on a roll.
It's ideal as a replacement for AFS SZG-05 Board
