3 Tension ranges available from 200 g up to 2000 g
32 mm Diameter Lightweight Rollers minimize bend on fragile materials
(Rollers are offered in Hardcaot Anodized Aluminum or Delrin Plastic)


  • NIST-Traceable Calibration Certification in optionally available
  • 32mm diameter V-grooved rollers are lightweight & ball bearing mounted for material speeds up to 4000 m/min
  • Large bending radius assures gentle handling of the material (rollers in Hardcoat Anodized Aluminum or Delrin Plastic)
  • Large, backlight LCD-display rotates in 90° steps for optimal viewing
  • 3 different display modes:
    – numeric
    – numeric with bargraph
    – numeric with graph (Time-Tension)
  • Automatic "Zero-Setting" in all measuring positions using built-in gravity sensor
  • 4 Seperate Calibration Material memory locations for custom calibrations (can be performed by end-user and saved with alpha-numeric name)
  • User-set Min and Max alarms with indication on LCD if reading is out of limits
  • High speed internal data sampling (8 kHz) for capture of accurate Min & Max Peaks
  • User-Selectable units of measurement: cN, daN, g, kg, N, lb
  • Storage of Min, Max and Last reading as well as Hi-Peak, Low-Peak, average and standard deviation
  • Setup parameters can be password protected so they are not accidentally changed by the user
  • Rugged aluminium housing with rubberized handle provides a secure and comfortable grip
  • Rechargeable Lithium Polymer Battery provides 40 hours of continuous operation
  • CE certified
