What should be paid attention to when purchasing a laser rangefinder?
Laser rangefinder telescope, this type of laser rangefinder has a long measurement distance, generally 500-2000 meters, and the longest measurement distance can reach 20 kilometers. Let's take a look at the purchase of laser rangefinders!
Here are a few things to consider when purchasing a rangefinder:
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 when the accuracy requirement is not high. It is recommended to use "Ultrasonic Range Finder".
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 with high precision requirements.
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.
daily maintenance
Problems that need to be paid attention to 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 rangefinder is not waterproof, so you need to pay attention to waterproofing.
Since the laser rangefinder is mainly suitable for outdoor enthusiasts in the local area, the advantage of its production is that it can be waterproof and anti-fog, and it is equipped with jungle tree branches and leaves.
The laser does not have the function of anti-drop, so the laser rangefinder is easy to break the light emitter.
