Electronic Digital Theodolite FET 420K series has adopted
increment-mode digits system for angle measurement.
The resolving power of horizontal and vertical angles can reach 10”.
The precision of angle measurement can reach 20”.
Electronic Digital Theodolite FET 420K can be widely used in 3-4 class
national triangle control measurement, precise lead measurement,
engineering measurement for mine? railway? water conservancy and so
on, landform measurement, and also could be used in the assembly of
the large machinery facilities.
The displays are illuminated so as to make it convenient to operate in
the darker environment.
