A series of new display chip, screen and font have been appied to 442UT. Measurement values are displayed clearer and with bigger size. The display performance under low light conditions also is better than before.

• 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.

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.

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”.
