Easy-to-use, accurate instruments for construction and survey environments
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.

One-touch keys for common functions
NE-100 series theodolites feature five easy-to-use, one-touch keys: four to perform all common functions and a fifth to control the backlit LCD display and reticle illumination. You can instantly convert vertical angles to percent of grade, reset the horizontal angle to zero and lock the horizontal angle displayed on the LCD while you reposition or repeat a measurement.

Angle accuracies to choose from
Angles accuracies differ between the models. The NE-100 offers 10" angle accuracy, while the NE-101 offers 7". Both the NE-102 and 103 models offer 5" angle accuracy.

Extra light for dark conditions
NE-100 Series theodolites feature a built-in reticle illuminator and backlit LCD display that allow you to work inside buildings as well as in tunnels, mines and other environments with little or no light. These features also come in handy during low-light conditions outdoors, such as near dawn or dusk.

Rugged, all-weather reliability
With the Nikon NE-100 Series theodolite models, you can count on reliable performance in tough conditions. The NE-100/101models have an IP54 rating, meaning water can splash on them from any direction with no harmful effects. Nikon NE-102/103 models have a higher rating of IP56 which means they're waterproof and dustproof.

Works longer on standard AA batteries
Unlike other instruments that require specialized batteries, NE-100 Series theodolites use six standard AA alkaline batteries. What's more, those batteries can power all models for about 48 hours. A three-level bar graph on the LCD screen displays remaining battery power.

Built to perform
Nikon NE-100 Series theodolites perform well in rugged environments. Even if you work in dust and water, these instruments are protected from the elements. Plus, the NE-103 has a vertical compensator.
