SCHMIDT scales are manufactured according to the most stringent quality requirements. Printed scales are not used. Instead, each scale is individually marked for the instrument involved. This ensures highest quality. Our special procedure makes it possible to provide tension meters

  • calibrated to custom supplied material
  • fine tuned to a specific tension range
  • other units of measure such as g
