Description
Theodolite Angle-Measuring Digital Theodolite LP402L Surveying Instrument
LP402L Digital Theodolite
|
LP402L is the Digital Theodolite with laser pointer function. It can provide an adjustable laser beam which can be seen up to 150m away through eyepiece in daylight. The laser emitting system is integrated with telescope, resistant to dust, rain and other harsh elements. Repeated angle program carries out continuous measuring and average calculating to get high-accuracy angle value. It has lower power consumption and longer working time with one battery.

FEATURES AT A GLANCE
|
1)Compact design with wide LCD display facilitates numberical reading and operation
2)Laser pointer brightness and focus adjustable 3)Minimum reading: 1″/5″/10″ 4)Lower power consumption, longer working time with one battery 5)
◆Laser point can be observed through the eyepiece
In addition to directly seeing the laser spot on the target, laser pointing and telescope visual observation can be carried out at the same time. Through the telescope visual observation, clear laser beam spot can be seen in the field of view.
◆ Laser point counter
Conventional laser point counter is prepared, optical point counter can be selected.
◆ The laser point brightness can be adjusted
Pointing laser power adjustment range is large, according to the intensity of the use of environmental light, by adjusting the potentiometer and from the telescope visual observation, in the field of view can always see clear laser beam spot.
◆ Integrated laser
The integrated design of laser pointing part and telescope makes the overall appearance of the instrument more harmonious and beautiful.
