Classification and selection of laser distance meters
Laser rangefinders have ultrasonic rangefinder, handheld laser rangefinder, laser rangefinder telescope (telescope laser rangefinder), one is to determine your measurement range; the second is to determine the accuracy of the measurement; the third is the use of the occasion. In the purchase of the following points need to pay attention to:
First, if you only need to measure the distance within a few meters or a dozen meters, and the accuracy requirements are not very high: you can choose "ultrasonic rangefinder". Due to the ultrasonic rangefinder measurement effect is affected by the environment, its stability and directionality is worse than the laser rangefinder, but its price is relatively cheap! More suitable for indoor measurement.
Second, the measurement distance is not long, more for indoor, high precision requirements: can choose "handheld laser rangefinder". This type of rangefinder in the indoor use of the most suitable *, its measurement accuracy and effect are very good!
Third, long-distance measurement, more for outdoor use: you can buy "telescope laser rangefinder" (ie: laser rangefinder telescope). Both telescope, and rangefinder; multi-fold observation magnification, the user only through the eyepiece internal cross aiming system, you can easily aim at the target for distance measurement. The use of harmless to the eyes of the transparent infrared laser emission and reception, can accurately measure the target distance, compact size and lightweight and easy to carry.
Fourth, measuring long distances and outdoor measurement: you can choose to have a built-in telescope, so that you can see more clearly in the strong light. As a result of the ease of fine * measurement.
Laser rangefinder use precautions: laser rangefinder can not be aimed at the human eye direct measurement, to prevent harm to the human body. At the same time, the general laser rangefinder does not have a waterproof function, so you need to pay attention to waterproof when using or saving.
The above is about the laser rangefinder purchase and use of some of the tips that need attention, the specific use of reference product instructions and manuals.
