The purchase of a distance meter needs to be considered from three aspects:
measurement range, measurement distance, and use occasions.
1. Small measurement range
It only needs to measure the distance within a few meters or ten meters, and the accuracy is not high. It is recommended to use an ultrasonic rangefinder. The measurement effect of the ultrasonic rangefinder is greatly affected by the environment, and the stability and directionality are worse than that of the laser rangefinder, but the price is relatively cheap! It is suitable for indoor measurement.
2. The measurement distance is not long
The measurement distance is not long, the ambient light is not complicated, and the accuracy is required to reach the millimeter level. The phase laser rangefinder can be purchased. The phase laser rangefinder is most suitable for indoor use, and the measurement accuracy can reach less than 2 mm. If the user needs to detect in the outdoor environment, due to the influence of ambient light, it is necessary to add a professional laser sight and reflector, and use them in combination to achieve the expected range and effect.
3. The measurement distance is far, and it is mostly used for outdoor use
Buy a telescope-type laser rangefinder, that is, a laser rangefinder telescope. The feature is that it is both a telescope and a rangefinder! With multiple observation magnifications, the user can easily aim at the target for distance measurement through the cross aiming system inside the eyepiece! Use the transparent infrared laser emission that is harmless to the eyes And receiving, can accurately measure the target distance, its small size, light and easy to carry!
4. Measure long distance and outdoor measurement
It is recommended to purchase a rangefinder with a built-in telescope, so that you can see more clearly in strong light and facilitate accurate measurement.
