Featuring a easy-to-use O.S with graphical display, N40 series total station enriches your surveying workflow with visual possibility and productivity. With extreme long-range EDM, quadruple-axis compensator, trigger key and powerful onboard applications, it allows you to work quickly and effectively from the first day.
Up to 1+1ppm, 1" angle accuracy. Or 1+1L5 | 2" angle accuracy.
With 1000m reflectorless range, N40 series total station is a powerful tool for all the surveying jobs.
The measurement can be taken at any time with just a simple button press by EDM trigger key.
You can measure and get the result without taking your eye off the telescope.
With red and yellow flash lights, the guide light is an efficient tool, helping to speed up your working when stake out.
With integrated LPDM module on laser plummet, N40 minimizes errors and accelerates the setup process onsite. Auto height enables the operator the get the instrument height with a simple press.
Transfer the data by versatile methods, for example SD card, USB or mini USB. It provides a faster connection to your laptop and Android mobile by Bluetooth.
Also you can export the data to data processing software via serial port.| Angle Measurement | Accuracy | N41: 1” N40: 2” |
