DT-105A
Tachometer

Hand-held tachometer for accurate contact measurement of revolution of engines or shafts as well as surface speed and length e.g. belts and conveyer belts

Tachometer with LCD display and many selectable units

High quality hand-held tachometer for professional use

Special Features

  • Hand-held tachometer DT-105A for contact measuring of revolutions, line speeds and length;
    the measurtement is carried out, as long as the measuring key is pressed
