Instruments are intended for determining the speed of rotation and linear displacements of objects, they have high resolution and high accuracy of measurements. The rotational speed can be measured before the different units: r/min or before r/s.

Tachometers are noncontact (optical), but it is possible to make their contact, for this is necessary option 9213 - complete set of caps for the contact measurement, it is acquired separately.

SPECIFICATION

Range of the measurements	1) r/min: from 30 to 199 r/min, and from 20000 to 99990 r/min, only 4 ranges. 2) r/s: from 0,5000 to 1,9999 r/s, and from 200,0 to 1600,0 r/s, only 4 ranges. 3) The total number of the revolutions: from 0 to 599999 (only for model 3404) 4) Period: the measurement of rotation pulses from 600 [mksekund] to 2 seconds (only for model 3404)
