Sonic Belt tension tester. Hz.
It arrived today in plastic box in foam. I will use it to check my timing belts on my Ducati. They have to be set at 110 Hz when plucked. I carried out a test by playing 110 Hz sound from a Website and you can see the results it was within 0.5 Hz which is well within the tolerance allowed on the testing apparatus. Thank you for a real quality test device.
