China Kolida Total Station Kts-442r4lcn Non-Prism 400m Total Station

KTS-442R4LCN
Product introduction:
2018 new model KTS-442R4LCN free prism infrared laser total station with a laser on the direction of the function, more intuitive, new SD storage cards, so that the mass storage and then expand 1G. KTS-442R4LCN in angle and distance measurement principle, optical structure, circuit schematics, electronic compensator, waterproof structure and the same, the difference is the red laser tube, light visible, greater power, using single prism can be measured at 5 km, non prism measurable 600 meters. The use of high technology to optimize the circuit to make the whole circuit more secure and reliable, the effective protection of the formation of the current, the battery working time is extended by 30%.
