Digital tachometer photo-contact

The handed digital tachometer DT2236 is a contact and a reflecting multifunction revolutions counter.
The instrument is built into a self-exstinguishing, anticollision plastic case.
The steel exit shaft revolves on high speed bearings.
The instrument and its fittings are keeped in a special bag.
Photo tachometer:
● apply a 10/12 mm long strip of tape on the revolving part and direct the pencil on it (distance 50/150 mm., 300 mm. maximum). In the case of low speeds put on some more strips. In this case the value displayed should be divided by the number of strips.
Contact tachometer:
● use special coupling drivers.
