How accurate are laser measuring tools?

Laser rangefinder is mainly used in underground coal mine to measure length, width, height, area and volume, and it is difficult to measure indirectly through Pythagorean law. Mine laser rangefinder is an instrument that uses laser to accurately measure the distance of the target. When the laser rangefinder works, it emits a very thin laser beam to the target, and the photoelectric element receives the laser beam reflected by the target. The timer measures the time from the launch to the reception of the laser beam, and calculates the distance from the observer to the target. Laser rangefinder is light in weight, small in volume, simple in operation, fast and accurate. It is mainly used for underground roadway measurement, topographic measurement, mine construction measurement and engineering construction measurement: measurement accuracy: ± 5.0mm (typical accuracy, standard deviation).

The error accuracy of normal standard laser rangefinder is as follows:

The basic error is 0.1M ~ 10m, not more than ± 0.05m

10m ~ 100m not more than ± 0.5m

100m ~ 200m not more than ± 1.0m

• 

• 1. Electronic level, compared with the bubble level, the tape measure has higher precision and faster angle measurement speed. The electronic angle is displayed in real time, it is easier to find the horizontal direction than other machines, and the measurement results are more accurate.

• 

• 2. Various measurement functions: distance/area/volume measurement, area/volume automatic calculation. Pythagorean measurements, single/continuous measurements; addition/subtraction measurements.

• 

• 3. It can measure a distance of 80 meters, and can be used for large-area laser measurement places such as home decoration, as well as large-area areas such as apartments, buildings, real estate, factories, warehouses, and industries.

• 

• 4. Voice broadcast, automatically read data, you can also set mute.

• 5. Powerful data storage function, which can store 50 sets of data.

• 6. Can be charged by USB, environmental protection.
