Tetko 10-100 Stretch Meter Description Tetko 10-100 Mechanical Stretch Meter The TetkoMat 10-100 is a portable, compact, mechanical tension measuring device for accurate and consistent measurement of all screen printing fabrics. The TetkoMat 10-100 was developed to Sefar?s specifications and is manufactured in Switzerland. It provides a simple, quick, and direct reading that measures in Newtons per centimeter (N/cm). N/cm is a unit of force measurement cited in the International Standard (DIN 16611A.2) for Relative Calibration of Tension Control Instruments. The high sensitivity of the TetkoMat 10-100 allows measurement control of tension variations within a screen regardless of frame size. This enables the screen maker to correct or change tensioning techniques to achieve the most uniformly tensioned screen. Correct and uniform screen tensions optimize screen life stability.
