TSA-154R for Gilson Testing Screens and TSA-153 for Gilson Test-Master® Testing Screens both feature a remotely-mounted digital controller that displays stroke values between 240 and 635 strokes per minute. Speed Variation Accessories can only be factory-installed in Gilson Testing Screen or Gilson Test-Masters® Testing Screens. Please inquire for retrofitting of existing units.
