The NA700 levels are tools designed to function reliably and precisely in tough working conditions, such as heavy rain, dusty environments, and construction machinery vibrations. Moreover, these levels have an IP 57 protection that protects them against dust and water, allowing them to be submerged without affecting their performance.

With the NA700 levels, downtime is minimized as their high brightness provides excellent contrast and a sharp image, enabling ergonomic and comfortable reading even in low light. Additionally, the nitrogen-charged eyepiece prevents lens fogging, ensuring clear vision at all times.

These levels feature the most stable and reliable compensator on the market, reducing maintenance costs to a minimum. Even in places with construction machinery vibrations, the NA700 levels deliver precise leveling results.

Moreover, the NA700 series offers a variety of levels suitable for each application, including distance measurement, datum line assignment, height difference definition, and height reading.
