Laser rangefinders generally use two methods, pulse method and phase method, to measure the interval. The pulse method ranging process is as follows: the laser light emitted by the range finder is reflected by the measured object and then received by the range finder, and the range finder records the round-trip time of the laser together. Half of the product of the speed of light and the round-trip time is the ranging.

Maintenance method of laser rangefinder:

The laser rangefinder is an integrated high-precision instrument of light, machine and electricity. It should be handled with care when using it. It is strictly forbidden to knead or fall from a high place to avoid damage to the instrument.

2. Clean the eyepieces. Use a soft dry cloth for the objective lens or laser emission window. It is strictly forbidden to use hard objects to depict, so as not to damage the optical function.

3. Check the appearance of the instrument frequently, and remove dust, dirt, grease, mildew, etc. in time.

Handheld rangefinder protection:

①Check the appearance of the instrument frequently, and remove dust, dirt, grease, mildew, etc. in time.

②Clean the eyepieces. Use a soft dry cloth for the objective lens or laser emission window. It is strictly prohibited to use hard objects to depict, so as not to damage the optical function.

③This machine is a high-precision instrument integrating light, machine and electricity. It should be handled with care when using it. It is strictly forbidden to knead or fall from a high place to avoid damage to the instrument.

In daily life, interior planners and architects often face a problem, that is, in the process of planning and decoration, they have a headache due to various measurement difficulties or hidden safety hazards that cannot be approached to the measurement site. Nowadays, laser rangefinders can handle similar problems well for you, easily measuring the length of various intervals or objects that cannot be approached to the address.

Local hand-held laser rangefinders, such as stairwells, elevators, etc., cannot directly contact the measurement guidelines, which can help you replace the traditional box ruler measurement and save manpower. Laser rangefinder is a high-function handheld rangefinder newly launched in recent years. Using patented planning, the measurement range is 0.05~200m, the measurement accuracy is 1-1.5mm, the measurement speed is fast, the use is simple, the plan is exquisite, and it can be carried and used. With this laser rangefinder, when measuring the volume of a house or a stairwell, there is no need for a lifting platform or a telescopic ladder, and the reading can be accurately measured in a few seconds.

In traditional measurement, there is a safety hazard if you cannot approach the measurement address. The laser rangefinder has a red laser dot, which allows you to clearly know where the measuring point is. Only one person is required to operate, and no other tools (such as ladders, etc.) can be used to complete all measurement operations, and even difficult-to-access parts can be easily dealt with, thereby avoiding injury accidents to the greatest extent.

In addition, in addition to the pocket portable planning, the rangefinder also has a length addition and subtraction function, so there is no need to curl up on the ground due to the measurement of the ceiling. With a large LCD backlit display, this laser rangefinder can easily read measurement data while aiming at the target. Using a laser rangefinder, one person can put it into operation, twice as fast as conventional methods.
