LASER BEAM AND PLUMMET PJK DE2A CHEAP DIGITAL THEODOLITE PRICES
DE2A Digtal laser Theodolite Features
The DE 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 life indicator on the LCD display.
DT02 Theodolite Key Advantages:
theodolite Product Description
Special design: single horizontal spindle which cross telescope
New design concept, combine higher precision, better stable specification and shock resistance ability.
Absoluteness angle encoder system
Able to read angle data without passing“0”, let angle measurement be more simpler and convenient.
Double CCD in each axle
Let measurement be more accurate,stable,and reliable.
Chinese/English Large display
Adapt backlight technology, able to display horizontal and vertical angle at the same time. Convenient to be used in different condition.
Down Laser point
Able to emit laser beam which in same axis with collimation of telescope,Make the instrument easier to set up and operate.
