Pipe Lasers TP-L4 series

TP-L4 series

	TP-L4 series are new pipe lasers that succeed the functions of the conventional TP-L3 series, but further enhance the basic performance. The pipe laser eliminates finishing stake and leveling string work as standards that determine the position, direction and gradient, significantly enhancing the work efficiency.
	Compared with a red laser, the green laser is several times brighter and its visibility is drastically higher. This green laser is mounted in the pipe laser. (TP-L4GV/G/BG)
	Laser beams can be irradiated in three directions - horizontal, up and down. (TP-L4GV/L4AV)
	High-speed auto alignment function is provided to automatically align the laser beam in the center of a target to increase the setup work efficiency subsequently in laser beam positioning work. (TP-L4GV/L4G/L4AV/L4A)
	Laser beam blinking mode is provided for easy finding of laser beam.
	Waterproofness: Protection class 7 or higher in JIS C 0920. Watertight type.
	Line control function to move laser beam left and right ±15%.
	Grade setting (control) at a high accuracy (0.01%) and in wide range (-150% to +400%).
	Full lineup of special accessories are available.
