TDS NE-101/100 Digital Theodolites

May 1, 2005


Tripod Data Systems (TDS) added the NE-101/100 models to its line of Nikon electronic digital theodolites. The NE-101/100 theodolites feature an easy-to-use, ergonomic keypad with one-touch keys for all functions. Both models include a 30x telescope; the NE-101 offers 7" angle accuracy and the NE-100 offers 10" angle accuracy for both horizontal and vertical angle measurements. A built-in reticle illuminator and backlit LCD display let users work inside buildings as well as in tunnels, mines and other environments with little or no light. The NE-100 Series theodolites can run for about 48 hours on six standard AA alkaline batteries. The instruments are lightweight but rugged, and they come with an IPX4 rating for all-weather operation. (TDS, Corvallis, Ore.)
