Sound tachometer ST-01 with non-volatile memory

It is intended for measurement of revolutions of the motor on the ground and in movement of model aircrafts, automodels, shipmodels. Measurement is made by a method of the analysis of spectral components of exhaust system of the one-cylinder duple engine of internal combustion from 5000 up to 65000 rev/min.

The note: indications for the one-cylinder four-cycle motor need to be multiplied on two.

Parameters of the device:

• Inaccuracy of measurements +/-0,02%
• It is possible to choose a range of measurement of revolutions of the motor
• It is possible to choose the coefficient of smoothing of indications (at astable work of the motor) for reduction of disorders of measurement.
• Non-volatile memory registers c the set periodicity the maximal values with an opportunity of viewing on the display of a tachometer
• Record is conducted in Russian or English languages
• Maximal time of record (at an interval 30 sec) 1 hour
• Maximum quantity of kept measurements 120
• Intervals of time of record 0,025...30 sec
• Feed from one battery of type the CRONE
• Weight of 147 gramme
• Sizes 84 x 60 x 35 mm
