The SRET Series model numbers that
reflect angle accuracy and have common features. All models have
dual displays, and a detachable tribrach. Horizontal and vertical
angles can be observed simultaneously on the large LCD displays.
Other standard features include a horizontal angle zero set,
automatic power off to conserve batteries, and a battery Iife
indicator on the LCD display.
Features:
·Large LCD display.
·Independent tilt sensor can auto corrected.
·International common function modes are adopted to make operation
simple and standard.
·Combined with various models of EDM's to form total station system.
·Connected with electronic book makes data fo be auto-recorded and
auto-processed maps.

The SRET-L Laser Series model numbers
that reflect angle accuracy and have common features. The laser line
has good visibility under 200m. Horizontal and vertical angles can
be observed simultaneously on the large LCD displays. Other standard
features include a horizontal angle zero set, automatic power off to
conserve batteries, and a battery life indicator on the LCD display.
Features:
·Good visibility of the laser line.
·Large LCD display.
·Independent lilf sensor can auto-corrected.
·More convenience when the instruments is combined with the Diagonal
Eyepiece.
·International common function modes are adopted to make operation
simple and standard.
·Connected with electronic book makes data to be auto-recorded and
auto-processed maps.
