Nikon NE 101

One-touch keys for common functions

NE-101 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.

Extra light for dark conditions

NE-101 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.

Works longer on standard AA batteries

Unlike other instruments that require specialized batteries, NE-101 theodolites use six standard AA alkaline batteries. What' s more, those batteries can power the NE-101 models for about 48 hours. A three-level bar graph on the LCD screen displays remaining battery power.

Rugged, all-weather reliability

With the NE-101 models, you can count on reliable performance in tough conditions. Nikon theodolites are lightweight, rugged and come with an IP54 rating. That means water can splash on them from any direction with no harmful effects.
