Overview for the Nikon DTM 322 5 Second Total Station

The Nikon DTM-322 Total Station with Nikon Survey software delivers accurate angle and distance measurements up to 6,560 feet away. With 5-second accuracy, this field instrument is ideal for surveying professionals looking for a device that easily connects to data collectors and can withstand harsh environments.

Legendary Nikon Optics

Nikon’s legendary optics integrated in the DTM322 effectively absorbs more light to give brighter, clearer images even in low-visibility conditions. Surveyors will see much more detail and much less distortion, especially over longer distances in the field. Better optics help surveyors aim more precisely, and they’re much easier on the eyes – something you’ll really appreciate on long workdays.

The Nikon DTM-322 is among the fastest total stations in its class, so you can move quickly through your routines and spend less time in the field. This land surveying tool is rugged and lightweight at 11 lbs including the battery.

Nikon Survey Field Software

With complete set of COGO and survey stakeout functions and simple data management, the Nikon Survey software has an intuitive and easy to learn user interface that enables users to conveniently collect field data. The quick field coding also allows for convenient one-button data collection of point features and raw target data for fast accurate results.

Convenient and Long-lasting Batteries

Using rechargeable Ni-MH AA batteries, the DTM 322 is designed to consume low power and provide the long usage in the field up to 15 hours! Off-the-shelf AA batteries can also be used as a back-up to provide even longer life.
