The Trimble TS635 Total Station is a rugged, mid-level surveying instrument designed for construction layout and measurement tasks. It combines precise angle and distance measurement with reflectorless technology, allowing users to measure hard-to-reach points without a prism, making fieldwork faster and safer. With built-in construction software, an alphanumeric keypad, and a durable IP66-rated design, it is widely used by contractors and surveyors for setting out structures, collecting topographic data, and performing general site measurements.
