Not the same as a prior line drawing device, without any limitation by long distance or high height, it is operating easy and quick with a high brightness 532nm green line laser module within 5mW to 100mW. It is an industrial stabilized line measuring tool. The basic use of thermal emitting system and APC, ACC driving circuit board are cooperating with different dimension tube, after its proper installation to correct position, it brings users high stability and long lasting green laser beam and green line alignment in long lasting use. 
The usual line alignment with a laser line generator should have to work for multiple working occasions. Being made with a qualified glass coated lens within 10 to 110 degree fan angles and strict laser beam stability test up to 24 hours, it is obtaining ultra fine and straight green reference line projection within 0.5 meter to 6 meters, and freely adjusted laser line fineness in use. Under operation with proper installation and adjustment to correct position, it always brings users the lowest price, the most stable and clearest line generation for both of industrial and high tech application fields.
Applications: laser cutting for stone, wood, metal, garment, steel, laser car wheel alignment, saw mill, lumber machine and high-tech
