Total station kolida KTS-442R4L 400m prismless
Kolida's new 440 series Total station
New advanced design with improved technology.
The new KTS-440 series was designed to deliver the latest technology to surveryor worldwide.
you will appreciate the technical improvement and advantages from the beginning of working with this equipment
Featuring an ultra-powerful EDM, the KTS-442R4 is able to measure up to 400m without reflector at an incredible 3mm+2ppm accuracy. and in prism mode it is able to measure up to 5000m with single prism.
Measurement are captured faster than ever :0.1s in tracking mode and 0.3s in fine mode. The bright red laser dot pinpoints are also featured.
Improved Optics system
442R4 is equipped with a newly-designed objective lens, now it has better tightness to resist adhesion failure, the water proof/ wind proof ability is also greatly increased .
The new receiving lens provides higher brightness in view field, a bigger signal-receiving area, increased the utilization rate of EDM signal. The measuring accuracy under sunshine/ foggy condition has been greatly improved.
A new coating technology was applied on Porro prism, now the laser became softer than before, It is safer to surveys' eye.
