* Per 1km double run
To improve accuracy a parallel plate micrometer can be fitted over the telescope objective.
The parallel plate micrometer permits direct readings to 0.1mm and estimated readings to 0.01mm. This makes the NA2 and NAK2 an ideal precise level for deformation studies or industrial measuring tasks.
The NAK2 model has an internal glass circle for reading horizontal angles. Combined
with the stadia calculation of distances from staff readings the NAK2 circle adds the application benefit of detail survey work.
