How to choose a more practical rangefinder detailed guide:
1. Look at the measurement accuracy: choose a rangefinder with an accuracy of ±2 mm, which can meet the conventional measurement requirements.
For some engineering measurements, including the distance between walls, the installation of curtains, etc., as long as the accuracy of the rangefinder is within ±2 mm, it can well meet the measurement distance.
2. Look at the measurement distance: the conventional selection measurement distance is 50 meters.
Now generally slightly better laser rangefinders have dual laser functions, which can better improve the measurement distance, and 50 meters can not only meet our conventional measurement distance, but also meet the distance that the laser can accurately reach.
3. Look at the battery life: choose a dry battery emergency that has both the function of direct charging and emergency power supply, that is, it has a dual power supply mode.
If the battery life of a rangefinder is insufficient, it will not only require us to charge frequently, but sometimes, when used for a long time, it will not meet our usage requirements at all.
4. Look at the material: generally choose a combination of external soft glue and hard glue material, choose silicone material for the buttons, and also have waterproof measures, then you can well achieve the performance of waterproof and anti-fall.
Because the general range finder is used in some places with harsh environmental conditions, choosing better materials can better prolong the service life of the range finder.
5. Look at the display screen: Select the display screen, it should be clear, and the data settings in the screen should be reasonable, so as to facilitate our reading.
If it comes with a voice function, it can provide another layer of insurance for our accurate readings.
