How to correctly choose a good range finder?
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.
*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! Suitable for indoor measurements.
b) The measurement distance is not long, the ambient light is not complicated, and the accuracy is required to reach the millimeter level
*Suggestion - Optional "Phase Type Laser Rangefinder".
*Remarks——The phase laser range finder is suitable for indoor use, and the measurement accuracy can reach less than 2mm.
(If the user needs to detect in an outdoor environment, due to the influence of ambient light, it is necessary to add a professional laser sight and reflector, and use it in combination to achieve the expected range and effect.)
c) The measurement distance is relatively long, and it is mostly used for outdoor use!
*Suggestion - buy "telescopic laser rangefinder" (ie: laser rangefinder telescope)
* FEATURES - Part telescope, part 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 can accurately measure the target distance by using the transparent infrared laser that is harmless to the eyes. It is small in size, light and easy to carry!
e) Measuring long-distance and outdoor measurements
*Suggestion - buy a built-in telescope, so that you can see more clearly under strong light.
*Remarks - for ease of measurement.
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.
