How to determine a multifunction green beam laser level is good or bad
We can measure from the following points
First, the light source
The vast majority of cheap multifunction green beam laser level on the market in order to save money with the use of ordinary green light. And this ordinary light source will bring the master very much trouble. Such as stray light, dark brightness, error! Give you a picture to feel it for yourself.
Second, the accuracy of the error
As a measuring instrument, the accuracy of the above must be more rigorous than anything else. But in fact, many machines advertised when they say 8M accuracy error ± 1MM, but the actual test is greater than 5MM, a serious exaggeration of the publicity effect.
Third, the range of capacity
This point is very critical! Work to the general sudden loss of power, who can stand it. So a good multifunction green beam laser level must have a very good range. Must be equipped with a good lithium battery, this point can not save money.
Fourth, remote control
This is also an excellent multifunction green beam laser level necessary function. Through the manual remote control to solve the high, narrow and other difficult terrain.
In this era of efficiency, a good machine can effectively help everyone save work time, especially in the decoration and repair industry, precision and efficiency is particularly important, so choose a good multifunction green beam laser level, can reduce a lot of unnecessary trouble.
