Product Description 

 Portable laser rangefinder YHJ-200J (hereinafter referred to as the instrument) dedicated smart chip, optical and electrical integration design, built-in bubble level, telescope sight, etc., can measure the distance of the target distance measured value is accurate, easy to use and so on. The YHJ-200J type rangefinder apply to the presence of inflammable and explosive gas mixtures, in the working environment to do the distance measurement. 
 The product is a new generation of intelligent optical mechatronics laser rangefinder. Telescope, data storage, laser automatically turns off the instrument automatically turns off, high accuracy, small size, light weight, easy to use and so on, can be widely used in the presence of inflammable and explosive gas mixture environment, measuring the distance of the target.
