The KR/RM-800 features a bright, new 8.5 inch color touchscreen panel to control the main  functions and an improved joystick operation due to a 23% reduction in weight from the previous models. Topcon systems have been renowned for their accuracy due to the proven Rotary Prism Technology. These new units feature this technology as well, so you take confidence, that accurate and stable measurements will be the norm.

Wide 8.5-inch touchscreen control panel
The new KR-800/RM-800 is equipped with a wide 8.5 inch color touchscreen panel featuring clear, easy to read icons allowing the operator full control of the unit during the measuring process.

Smooth movements
Topcon’s ability to engineer a weight reduction of approximately 23% has contributed
to a smoother operation of the unit when using the X-Y control lever. This all contributes to a more fluid measuring process and a more accurate end result.

One touch lock
Both new instruments are fitted with a quick and easy to use lock.

Easy load printer
The printer on the new units saves you time by eliminating the need to load new printer rolls. You simply drop the new roll in and print.
