What are the precautions when purchasing a laser range finder?
Laser range finders can also emit multiple laser pulses to determine whether an object is moving away from or approaching a light source through the Doppler effect. Due to the speed of light, this instrument is not accurate at close distances. Triangulation is more suitable when high-precision distance measurement on the order of less than a millimeter is required.
Precautions for purchasing a laser range finder:
1. Measuring range
2. Measurement accuracy
3. Where to use
It is basically divided into the following situations:
a) It only needs to measure the distance within a few meters or more than ten meters,
And when the accuracy requirement is not high. Suggestion - "ultrasonic range finder" can be selected.
Remarks—The measurement effect of the ultrasonic rangefinder is greatly affected by the environment, and its stability and directionality are worse than those of the laser rangefinder, but the price is relatively cheap, and it is suitable for indoor measurement.
b) The measurement distance is not long, and it is mostly used indoors, requiring high precision.
Suggestion - you can choose "Handheld Laser Rangefinder".
Remarks——The handheld laser rangefinder is most suitable for indoor use, and the measurement accuracy and effect are very good.
(If the user needs to detect in an outdoor environment, it is recommended to use a professional laser sight and a reflector to achieve the expected range and effect.)
c) The measurement distance is relatively long, and it is mostly used for outdoor use.
