Do you understand the application principle of YHJ-300J explosion-proof laser distance meter?

April 14, 2021

YHJ-300J explosion-proof Laser Range Finder is a new generation of intelligent opto-mechanical integration laser range finder. The instrument adopts ultra-low power consumption intelligent design. It has the characteristics of long working time, fast response speed and accurate measurement value.

Explosion-proof laser range finder generally uses two methods to measure the distance: pulse method and phase method. The process of pulse distance measurement is this: the laser emitted by the distance meter is reflected by the object to be measured and then received by the distance meter. The distance meter also records the time of the laser round trip. Half of the product of the speed of light and the round trip time is the distance between the rangefinder and the object being measured.

The YHJ-300J laser rangefinder also has a built-in telescope sight, backlit display, menu navigation, data storage, automatic laser shutdown, automatic instrument shutdown, high measurement accuracy, measurable large and small values, area and volume, volume Small, light weight, simple operation, easy to use and other functions and features, YHJ-300J laser rangefinder can be widely used for distance measurement in the presence of flammable and explosive combustible gas mixture environment.
