SZG-20B touch hand-held digital tachometer Tachometer
Summary.
SZG-20B touch hand-held digital tachometer is a type of high precision tachometer, it adopts photoelectrictransformation principle, through the contact way to test linear velocity and speed motor and all kinds ofmachinery and equipment, instrument using five LCD digital display, intuitive and accurate, convenient use,small volume, convenient carrying, wide application range.
SZG-441 photoelectric handheld digital tachometer,measuring range is a wide, high accuracy, multiple functions, convenient use of the tachometer, measuringspeed, speed and frequency. And with counting function.With the general non-contact handheld digital tachometercompared with small volume, beautiful appearance, feel better. With a piece of reflective markers in rotatingobjects to be measured using, tachometer visible lightreflective markers were measured at. A sense of amaximum value, minimum value alarm function, can storea maximum last measurement value and themeasurement process, the minimum value.
