Product Description

Introduction:

The stroboscope is a rotational speed and vibration measuring instrument that makes use of the persistence of vision (when the
ight source flashing at the set frequency is synchronized with the rotational speed of the object, a relatively static visual
persistence phenomenon occurs). Its working rinciple is that when observing an object rotating at a high speed or moving,
by adjusting its flickering frequency to be close to and synchronizing with the rotation or moving speed of the measuring object,
the measured object looks be moving slowly or static although moving at a high speed, this optical phenomenon of persistence
of vision makes it easy to observe the motion of high-speed moving objects with the naked eyes.
In this way, it is possible to measure the rotational speed of various types of rotating objects without contact, as well as to detect
he motion state and surface defects of the object. Its application is very wide, such as various types of rotors, gear meshing,
vibration equipment diagnostics, textile, printing, production lines and other high-speed rotating object surface defects and
motion trajectories.The photoelectric tachometer is a meter that uses the principle of light reflection, by sticking reflective tape on
the surface of the rotating object, and then calculating the time difference of the reflected light to obtain the rotating object's speed.
This instrument is a multifunctional instrument that combines a stroboscope and a photoelectric tachometer, which is convenient
for users to detect the state parameters of various rotating objects.

Performance features

* The advanced technologies such as micro-computer technology (CPU), software frequency generator and anti-jamming technology are applied to conduct non-contact measurement of rotation speed, as well as to inspect the status of
moving objects and detect defects on the surface.

* Large LCD with backlight ensures clear readings and no parallax.

* Efficient integrated LED light source module, flash pulse width controlled with speed, to ensure clear observation without tailing.

* In the photoelectric speed measurement mode, the maximum value Up, the minimum value Dn, and the last value Last can be
recorded.

* The stroboscopic adjustment methods include single-step adjustment and continuous adjustment as well as coarse and fine adjustment, which are convenient for fast and accurate
adjustment to the required flash frequency value.

* With pre-storage function, 12 frequently used strobe data can be stored, and can be recalled and used at any time, and the
measurement of speed is convenient and quick.

* The power supply adopts three AA 3.7V lithium ion rechargeable batteries (14500) to ensure long-lasting power. When the voltage is lower than the specified value, it will automatically prompt.

* The whole machine adopts durable and optimized electronic components, with accurate test data and stable performance.
The shell is made of light and hard ABS+PC engineering plastics, beautiful in appearance and easy to carry.
