Classification and selection of laser range finders
Laser rangefinders include ultrasonic rangefinders, hand-held laser rangefinders, and laser ranging telescopes (telescope laser rangefinders). One is to determine your measurement range; the other is to determine the measurement accuracy; the third is the use occasion. When purchasing, you need to pay attention to the following points:
1. If you only need to measure the distance within a few meters or more than ten meters, and the accuracy requirement is not very high: you can choose "ultrasonic range finder". Since the measurement effect of the ultrasonic rangefinder is greatly affected by the environment, its stability and directionality are worse than those of the laser rangefinder, but its price is relatively cheap! More suitable for indoor measurement.
2. The measurement distance is not long, and it is mostly used indoors. When the accuracy requirement is high: "handheld laser rangefinder" can be selected. This type of rangefinder is most suitable for indoor use, and its measurement accuracy and effect are very good!
3. Long-distance measurement, mostly used for outdoor use: "telescopic laser rangefinder" (ie: laser rangefinder telescope) can be purchased. It is both a telescope and a rangefinder; with multiple observation magnifications, the user can easily aim at the target for distance measurement only through the cross sight system inside the eyepiece. It emits and receives the transparent infrared laser that is harmless to the eyes, can accurately measure the target distance, and is small in size, light and easy to carry.
4. Measurement of long-distance and outdoor measurement: You can choose a built-in telescope, so that you can see more clearly under strong light. Due to the ease of precision measurement.
Precautions when using the laser rangefinder: The laser rangefinder cannot be aimed at the human eye for direct measurement to prevent damage to the human body. At the same time, the general laser range finder has no waterproof function, so it needs to pay attention to waterproof when using or storing.
The above are some tips that need to be paid attention to when purchasing and using laser rangefinders. For specific usage, refer to product instructions and manuals.
