Selection Guide for Laser Distance Meters
1. Measuring range
2. Measurement accuracy
3. Where to use
Basically divided into the following situations:
a) It only needs to measure the distance within a few meters or a dozen meters,
And the precision 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 that 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 as shown in the left picture".
Remarks——The handheld laser rangefinder is suitable for indoor use, and the measurement accuracy and effect are very good. When measuring outdoors, due to the influence of outdoor light pollution, the accuracy of the handheld laser rangefinder drops significantly.
(If the user needs to detect in an outdoor environment, it is recommended to use a laser sight and a reflector in combination to achieve the expected range and effect.)
Note: The continuous output laser used by the laser rangefinder is visually in the red spectrum range. When the eyes look directly at it, it may cause irreversible damage to the eyes.
c) The measurement distance is relatively long, and it is mostly used for outdoor use.
Suggestion - buy "telescopic laser rangefinder" (ie: laser rangefinder telescope).
