In the middle of May, our Surveying Division delivered Trimble S5 robotic total station and Trimble Dini digital level to Italian-Thai Development PLC. at Maemoh district Lampang. Both instruments will be used for high precision surveying in Maemoh mine. There are several features in Trimble S5 robotic total station that assist all surveyors to work easier and more efficient. The Trimble S5 can search and turn to prism target automatically in 500-700 meters range in no time. Thanks to Trimble Magdrive Technology that make the Trimble S5 turns to every target with smooth and silence. High precision measurement can be easily done by the help of Trimble DR plus EDM which make every angle and distance measurement faster and more accurate.
