Designed for general construction and survey applications, Nikon NE-100 Series electronic digital theodolites from TDS give you accurate measurements in an affordable, easy-to-use platform. Nikon NE-100 Series theodolites can run 48 hours under normal operating conditions on a set of six AA alkaline batteries. Each of the four models has an ergonomic keypad with one-touch keys for all functions and a large, backlit LCD display help you work productively in the field. .

Ultra-long working hours

With Sokkia's new algorithm in operating absolute encoders, power consumption has been dramatically reduced. Powered by 2 standard LR14/C alkaline batteries, the DT210 and DT510 will operate for 75 hours, while the DT510A and DT610 will work for an astonishing 110 hours.

Easy-to-read, easy-to-use control panels

A large LCD screen provides clear angle readings under all conditions, and thanks to simple 4-key operation no training is required. The DT210 and DT510 have control panels on both faces for added convenience.

Dual-axis compensator

The DT210/DT510 automatically compensate both Vertical and Horizontal angles by monitoring the tilt of instrument in X&Y two directions.

Audible right-angle notification

Once the zero(0) horizontal angle direction is determined, all models emit audible tones for each of the four right-angle directions. Specifically, it sounds two different tones within ±15° of 90° and stops beeping when it comes within ±1°.

Superior IP66 protection

Complying with the tough IP66 standard for resistance to dust and water, both models offer superior dependability even under harsh environmental conditions.
