...simply by putting the Sirometer on the machine's housing
you can measure the number of revolutions and frequency of each running engine or operating machine with great accuracy.
With the TREYSIT Sirometer you do not need to access the often hard accessible shafts or turning parts, because it analyses the the number of revolutions or frequency through the vibration of the housing and shows it on two scales.
You can easily read off the number of revolutions and the frequency on the two scales when the measuring gauge on the upper disk shows the strongest oscillations.
The TREYSIT Sirometer is the simplest testing device for versatile applications with checks, measuring comparisons, investigations, etc...
It is checked and certified by the Federal Standards Laboratory in Braunschweig, Germany and indicates with a tolerance of 1-2% a sufficient accuracy for the usual measurements.
