1. Applications and functions
Straight direction and centralized energy are laser's characters, GPI-ZL21R, add
two laser diode bases on optical plummet, one laser beam through telescope. The
other laser beam are directed down through the plummet, it is easy to locate a
given reference point. The design ensure laser beam and telescope axis on same
center, same axis and same focus. There will be a red laser spot on the target
which you aimed.
It
is safe for user to observe laser from eyepiece. And laser
target makes your work more directly and convenient. Otherwise, there is a laser
target sheet as standard accessories; it is more convenient for measurement.
It
is
easy to measure with horizontal circle. The design is portable and stable.
It
can
be used in measuring small horizontal deviation, transfer on vertical direction,
measuring the object's outline.
It
is used widely in construction, industry
installing, engineering inspecting and distortion observation as well as many
others engineering survey.
