The Nikon NE-202 theodolites feature a large, backlit LCD graphic display and keypad on both sides. Either screen can display both vertical and horizontal angles simultaneously.

One-touch keys for common functions

Four one-touch keys make the NE-202 easy to use. Common functions are simple to perform—you can instantly convert vertical angles to percent of grade, reset the horizontal angle to zero, lock the horizontal angle displayed on the LCD while you reposition, or repeat a measurement. Operation is simple and efficient.

Rugged and waterproof

With Nikon theodolites, you can count on reliable performance in tough conditions. Our theodolites are both rugged and waterproof. They have an IPX6 rating, meaning they can withstand powerful jets of water with no harmful effects.

Extra light for dark conditions

Our theodolites feature built-in reticle illuminators that provide a clear view of the crosshairs to help you work in tunnels, mines or other environments with little or no light. The LCD graphic displays are backlit as well, so you can read them easily even in the darkest conditions.

Focus to 2.3 ft.

The NE-202 feature a 30x telescope with a 45-mm objective aperture diameter. And Nikon's unique linear focusing mechanism improves focusing at both short and long distances. The minimum focusing distance is 2.3 ft. (0.7 m), so you can see sharp images even in confined spaces.

Power management feature

The NE-202 can work for one hour more on either battery. You can extend battery life by setting the instrument to automatically shut off after 10 or 30 minutes of inactivity. And the power save function retains the last horizontal angle on display, so you can get right back to work.

Built-in vertical compensation

The built-in vertical compensation ,automatically compensate to ensure precise vertical angle readings. The NE-202 have an accuracy of 5".
