Sokkia' s LDT520, a 5� digital theodolite equipped with a telescope with laser beam emission capability, boasts the world’ s longest laser range, class-topping dust and water protection, and a continuous operation time over 2.5 times that of its predecessor. The LDT520 is designed for directional controls in tunnel excavation, precise marking and alignment in construction and engineering applications.

Major improvements over the previous model World’ s longest laser range

* The LDT520 offers a 600-meter ( 2, 000 ft.) * beam range from an easy-to-handle Class 3R laser.

Dust and water protection at the top of its class

* The LDT520 achieves an IP66 rating, the highest level of dust and water protection in a theodolite.
* The LDT520 is rated the highest level “ 6� for dust protection in the IP code specified by the IEC. The unit is shielded from fine powder-type dust.
* The unit’ s water protection is also rated at level “ 6� , the highest level for a theodolite, enabling it to be used with
* confidence under moist underground conditions.

Absolute encoders

* Newly equipped with the market-proven advanced absolute encoders for higher reliability and lower power consumption.
* Provides 5� angle accuracy with resolutions of 1� / 5� , 0.0002/ 0.001 gon or 0.005/ 0.02 mil.

Longer battery life

* The LDT520 achieves a continuous operation time over 2.5 times that of the previous model, using a standard detachable battery.
* Continuous use for 12.5 hours at the maximum output of 4.5 mW and 13.5 hours at 1 mW.
* Supplied with two batteries.

Operable in tighter spaces

* The minimum focus of the optical plummet has been reduced from 20cm in the previous model to 15cm.
* Can be precisely set at 15cm ( 5.9 in.) directly above the reference point.

Unique feature of the SOKKIA laser digital theodolite Emits both focused and parallel beams

* When the focused beam is used, the diameter of the beam spot is smallest at the point of focus of the telescope.
* When the parallel beam is used, the beam diameter remains constant at any distance, making the unit ideal for directional control in tunnel excavations.
* The parallel beam can be focused by simply adjusting the telescope focusing ring to the mark. No external
* accessories are required.

Major applications

* Directional control in tunnel excavations using NATM or Shield Machines ( using a parallel beam)
* Precise alignment and positioning in construction projects ( using a focused beam)
