1. What are the advantages of laser distance measurement sensors?

The equipment is small in size and high in accuracy, has a wide range of applications, and is cost-effective and economical.

2. What issues should be paid attention to when choosing a laser ranging sensor?

First of all, it is necessary to pay attention to the structure and material of the measuring object. The uneven phenomenon of the measuring object and the use of reflective materials often directly affect the use effect of the laser ranging sensor. Secondly, it is necessary to pay attention to the parameter indicators of the sensor, because the accuracy of the parameters also directly affects the accuracy of the measurement.

3. What should be paid attention to when using the laser measuring sensor?

Pay attention to check before use and avoid using faulty instruments, do not aim at strong light sources or reflective surfaces, avoid shooting at the eyes, and avoid measuring unsuitable surfaces.
