1000m Extreme Long-range Laser

Pinpoint laser pointer provide long-range and reliable aiming in the pipe jacking constructions, for the micro-tunnels, pipelines and culverts, etc.

External Power Supply for Full-Days’ Work NT-02D supports the external power supply for any full-days’ work, which eliminates the need for recharging or carrying extra batteries.

Aplications

A Simple but Practical Measuring Too

With a laser plummet for simple and quick setup, single axis compensator, beeping for 90 degrees turns, NT-02D is a practical measuring tool for your daily work.

When Theodolite Meets Pipe Jacking.

Pipe jacking, generally referred to in the smaller diameters as micro-tunnel, is a technique for installing underground pipelines and culverts. When pushing the specially designed pipes through the ground behind a shield, NT02D offers an accurate laser pointer with extreme long range, which will largely decrease the deviation of center axis and elevation.
