Five New Improvements in 2021, to Level Up Your Productivity!

  • A new central processor unit (CPU) has been used in 442UT, the instrument calculates faster and the battery consumption is lower than before.

  • The built-in memory storage space has been improved from 4MB to 12MB, which can store 96,000 points.

  • Trigger Key and standard USB port have been added to 442UT. 

  • Battery compartment is with new design and easier to handle.



Measures Longer and longer, Improvement Never Settles!

How could we lift the ranging cabability to a new level of 1000/1500m? The three key factors are "Dual-light Source Distance Measuring technology", optimization of the signal-to-noise ratio, a more stable objective lens system.

A New Step to be More Accurate, Innovation Never Stops!


Every hard working surveyor deserves a higher precision than before. 

Four innovations have been realized in our newly designed optical system to achieve this goal: "Focal Length Compensation Mirror", "Fully sealed emitting laser circuit", "Less reflectors in optical part", "the 4th Generation EDM CPU".



Practical Survey Program


Various of surveying programs onboard allow surveyors to complete their tasks directly in the field: angle offset, angle repetition, dual-distance offset, coordinate measurement, REM, MLM, Staking out,area calculation, Road Design, etc.



Compatible with FieldGenius

Working KTS-442-UT with graphic mapping software such as Microsurvey FieldGenius will optimize your productivity.



Convenient Data Transfer


KTS-442-UT supports SD Card/ Mini USB / Serial port cable/ Bluetooth connection. Special data transmission and editing software can quickly transfer data and save time. 




External device can be linked to total station, through the Bluetooth™ wireless connection. Then users can use their PC/ tablet/ Data Controller with 442-UT total station and run mapping software to collect data.
