Click images to enlarge.
The CHECK-LINE® BTM-TTC accurately measures the oscillation frequency of flat, V and ribbed belts of rubber, leather, fabric and composite materials by measuring the natural frequency (Hz). The tool operates by using a very sensitive microphone that analyses the resonance frequency. The small dimensions and the ease in use make BTM-TTC a practical and reliable tool.


  • Belt Tension Is measured in Hz units (frequency)
  • If tension measurement in Newtons or Lbs units is required, refer to BTM-400PLUS webpage
  • It is entirely wireless and self-powered by rechargeable batteries
  • It requires no additional tools as it displays the test results directly on its graphic display
  • Battery charger supplied as standard
  • It emits a beep once the measurement is complete
