The 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
