During the detection process, the internal image of the detected object can be recorded and stored in real time. During the recording process, the defect image can be quickly captured and saved, or the text information is input through the keyboard, displayed and saved in the video picture, and the defect code can be entered quickly through the function key. It is highly integrated, compact and portable, and is equipped with built-in high-performance battery. It is suitable for mobile working environment in the field.   

Factors affecting measurement

Laser range finder is an optical instrument whose operation will be affected by environmental conditions. Therefore, the measured range can be different when applied, and the accuracy of ranging is also affected by these factors. The following conditions may affect the measuring range:

1. Rough surface and color effects.

When measuring rough surface (such as plaster wall), the center of a bright area is aligned.   

2. Surface transparency.

In order to avoid errors in measurement, do not measure the surface of transparent objects, such as colorless liquids (such as water) or glass (dust-free). For unfamiliar materials or liquids, test can be done first. When there are several objects in the target or light path through the glass, there will be errors in the measurement.   

3. Moist, smooth or glossy surface.

When the aiming angle is very small, the laser will be reflected off. The signal received by the sensor will be too weak or the target distance reflected by the reflected laser can be detected.  

4, inclined plane and round surface

Only when the target area is large enough to accommodate laser spots can it be measured.   

♔5. Measures to increase the accuracy of measurement.

When measuring objects of different colors and materials, we must try to test them in case of condition, so as to get more accurate data.   

When measuring, there should be no obstructions (such as transparent glass, splashed water droplets, spider web, etc.) on the optical path to the target.   

Keep the air in the measuring environment clean and reduce the test time in the harsh natural weather such as dust, fog, rain and snow.   

Minimize the angle between the optical path and the target, so that the received signal can be increased.   

Only when the target area is large enough to accommodate laser spots can it be measured.   

🌃When measuring, the sensor should be fixed and reliable, and can not be swayed at will.
