The Northwest Instrument NTS02B Reflectorless (2-Second) Total Station is a rugged and highly-accurate device used by land surveyors and civil engineers to record topographic data. With built-in EDM laser (Electronic Distance Meter), Bluetooth and an improved absolute encoder, this survey total station is ideal for precise distance and angle measurements.

Reflectorless Accuracy

With 2-second accuracy and 30x magnification, this survey tool allows you to measure slope distances at up to 984 feet. You also have the option to extend the NTS 02's measuring capability to approximately 6,500 feet using a single prism.

This reflectorless total station is also perfect for taking measurements where you cannot reach or use a prism. Its tilt sensor also ensures perfect leveling of the survey device. 

Enhanced Absolute Encoder

The NTS02B allows land surveyors to continuously take stable and reliable angle measurements without the need to return to the starting point by detecting an absolute position as soon as the power is turned on.

Versatile Connectivity

The Northwest Instrument NTS02B features Bluetooth connectivity for wireless data collection and 20,000 points of memory for storing large amount of field data. It also has on-board software and you can easily download and upload files via the RS-232C and USB ports.

Excellent Features and Functionality

This field surveying instrument has a laser plummet to precisely mark your total station's location and a laser pointer to focus on the exact point you need measured.

Using the alphanumeric keyboard and soft keys, you can enter data and quickly display functions. With an illuminated LCD displays on both sides of the 2-second total station, you can view the screen from any direction.

High Durability and Long Battery Life

The NTS02B survey instrument has an environmental rating of IP-55, protecting it against dust and water jets from any angle. The rechargeable Li-Ion battery also provides up to 9 hours of continuous distance and angle measuring, or up to 24 hours measuring angles only!

This Northwest Instrument total station package comes with a serial RS-232C cable, USB data transfer cable, rechargeable Li-Ion battery, battery charger, rain cover, hard carrying case, CD-ROM, user manual and a 3-year manufacturer's warranty.

With Bluetooth connectivity, 2-second angular accuracy and reflectorless measurements up to 984 feet, the Northwest NTS02 total station meets the precision and durability that construction and survey professionals need at a great price.
