YHJL90/360 Mine-used Intrinsically Safe Laser-pointing Hole-opening Direction Finder

Product Introduction

The YHJL90/360 mine-used intrinsically safe laser-pointing hole-opening direction finder (hereinafter referred to as the hole-opening direction finder) is a portable mine-used intrinsically safe hole-opening direction finder, mainly used for occasions where azimuth measurement is required in underground coal mines. It is applicable to all places in underground coal mines where there is a risk of gas or coal dust explosion.


Product Features

1.Small size, easy to carry, install, and with good protection performance.

2.It adopts a software anti-interference algorithm, featuring high measurement accuracy.

3.It has a wireless Bluetooth communication function, enabling functions such as data query, storage, upload, and printing.

4.It has a cross laser line direction indication function, which is convenient for observing the working state of the hole-opening direction finder.
