Review Total Station Topcon GPT-3000LN
GPT-3000LN |
|
1200m Power PULSE: | "Power PULSE" 1.2km prismless measurement is useful for measurement at inaccessible area like landslide, steep slope at road side, Dam and Bridge. Also usable for wide area volume measurement & calculation in construction / mining site. 2.4km diameter of prism workable range without prism will greatly boost up your field productivity. |
AAA
|
Reality of actual prismless measurement could be affected by many factors, such as color/material/shape of object, weather condition and so on. AAA feature of GPT-3000LN guarantee your comfortable prismless measurement upto 350m at any condition (Anything, Anytime, Anywhere). Even at longer distance, much higher capability to "catch" the distance than usual prismless technology. |
Dual Optical System
|
GPT-3000LN provides not only prismless but also prism measurement (3000m /1prism) by its unique "Dual Optical Design". Reflectorless measuring requires a finely focused beam for pinpoint accuracy. Prisms need a wider pattern to prevent off-center measuring degradation. Topconfs dual-optical system gives you both for the maximum measuring accuracy all the time. |
"No Error" Pulse Laser
|
Topcon's unique "No Error" pulse laser based reflectorless measurement eliminates measuring errors caused by the overlapping signals used in phase measuring systems. Accurately measuring corners or through objects such as a chainlink fence is always fast and reliable. |
"Eye-safe" Pulse Laser
|
Distance measuring laser of GPT-3000LN is "Eye-safe" invisible laser (Laser Class 1). It is possible to work safely even at busy urban / city area. |
Powerful Onboard Program & Built-in Data Collector |
GPT-3000LN comes with powerful field program for land survey & construction. "Road Survey Program" is newly added to this class of total station, which will definitely improve the field convenience in road works. Built in Data Collector Capability has also been enhanced, which now supports 24000 points data recording for Topo or Layout data. - Coordinate Measurement - REM (Remote Elevation Measurement) - MLM (Missing Line Measurement) - Offset Measurement - Stakeout - Point to Line - Data Collection (24,000 points) - Road Survey Program |
