FOIF EL302A high precision digital level
Application:
EL302A digital level is designed with new coding technology, which can maximize work efficiency and minimize human error, providing consistent measurement precision and speed, regardless of operator skill; Also auto compensator is adopted for high measuring accuracy and working efficiency. Model EL302A Digital Level is adoptable for the Second or Third-order geodetic leveling of national networks; It can be used for engineering and deformation surveys, such as height control for engineering projects, deformation and subsidence measurements, checking bridges and structures, monitoring movements, etc. It is also used for general construction engineering and installation of large size machines.
Nomenclature:
