Q:What brand of laser level is good? How much is the price?

A level instrument in which laser beams are used instead of manual readings. The laser beam emitted by the laser is introduced into the telescope cylinder to send a horizontal laser beam along the collimation axis. By means of the monochromatic nature and the coherence of laser, a piece of glass or a piece of metal with a certain shading pattern can be assembled in front of the telescope object lens, that is, the zone plate can cause diffraction interference. Through the telescope focusing, the focusing range zone plate, a bright and fine cross shaped or circular laser spot, thereby more accurate sighting target. If the photoelectric receiving target can be automatically tracked on the front and back level scales, leveling can be carried out. In the construction survey and assembly of large components, the laser level was used to establish the horizontal or horizontal lines in 1989.Digital level is the most advanced level, with a special bar level, through the instrument built-in digital imaging system, automatic level bar bar code readings, no manual reading is needed. This instrument can greatly reduce the labor intensity of Surveying and mapping work, avoid the subjective subjective reading error, and improve the measurement accuracy and efficiency

Q:What happens when the vertical level of laser level is tilted?

The deviation is small and can be calibrated and will have to be repaired. Besides, is your horizontal line also crooked?

Q:In the decoration, why use laser level instrument out of the horizontal line, hit on the wall, there will be a slight jitter? The farther away, the greater the jitter

How do you use in the three foot is a little shaking because of the house and car such as heavy automobile engineering piling machine and so on is to have a laser level sensitivity is too high or the machine has some problems in the outside world a slight shock

Q:BOSCH low level instrument to see the comment, the line out too thick. Are there any other good brands to recommend?. There are so many brands on Taobao that they look dazzling.

With the laser 629, can also be. Key switch, light combination is a bit wordy, direct each light a switch is not good? 1.6m three feet are not enough. Draw the top of the wall and put on the shelf. Is the 4 batteries of 5 large power consumption, although three line plus points should not exceed 100mA, the actual (current value can not too accurate): 30mA. Single open horizontal line, about 130mA. A horizontal line and a vertical line is about 170mA. Three wire fully open, more than 200 mA. The strange thing is calculated first line 40mA, but the first single vertical machine about 100mA, looking forward to the expert introduced the circuit. The environment is not too bright, you can use pulse mode, the line brightness is not very different, the power consumption down to three lines, when fully open about 160mA. BOSCH electric chainsaw hammer is not how good, electronic instrument. Such as wall detectors and laser range finder, although the materials used, fine workmanship, but used in general, high prices. GSR 10.8-2-LI rechargeable drill chuck big shake has been criticized. I wonder how the chucks of DEWALT rechargeable drills are?. Drill bit by the carpenter's drill, but not straight, fortunately, the drill material can be, straight back, some did not break. HSSG high-speed steel twist drill set is also available, can drill stainless steel plate, but the price is high, or domestic cobalt drill bit benefits. The Italy imported electric hammer chisel not see how hard, a few dozen blocks a domestic chisel seems more cost-effective.

Q:When the laser level is opened horizontally, it does not move on one line when it moves around. How can it be corrected?

Move the instrument around? If so, it is because of the uneven terrain, the height adjustment can be.If it's spinning around, that's the instrument itself. Need to be calibrated or repaired.

Q:The role of the bottom magnet of the laser level

Specializing in the sale of precision measuring instruments - Wuxi Rongsheng

Q:How many lines of laser level instrument do you need to stick the floor tile?

3 lines can be used, of course, the 5 line is better

Q:How can the laser level adjust the height of the horizontal line?

You can fix the level on the three stand and adjust the height of the horizontal line by adjusting the height of the three leg.Laser level meter operation mode:When measuring, the working surface of the level instrument is close to the tested surface, and the reading can be carried out until the bubble is completely stationary.The graduation of the level is based on the slope value of one meter as long as the actual tilt of the length of L is calculated by the following: the actual slope = the value of the division *L*, the number of deviationsIn order to avoid the measurement error caused by the zero position of the level instrument, the zero level of the level instrument must be checked or adjusted before use.Level zero calibration method: the horizontal instrument is placed on the base of the stable and approximately horizontal plate (or machine tool guide rail). When the bubble is stable, the end is read at the end, such as the left end, and zero. Then turn the level of 180 degrees, still placed in the original position of the plate, to be stable after the bubble, still in the original one (left) readings A, the level of zero error is two points A grid. If the zero error exceeds the permissible range, then adjust the level zero adjusting mechanism (adjustment screw or nut, the error is reduced to zero within the allowable value. The nut shall not be turned freely for the screws which are not specified.

Q:Home decoration, heard by the laser level meter stick tile floor tiles more accurate and convenient, do not know which one to buy?

There are very few lines on the top of the gray cake, their own construction, play the wire bar, rich or laser level instrument.

Q:What's the use of an automatic laser level?

Paving tiles will be used to find horizontal and vertical lines
