Engineering Surveying Equipment

The engineering surveying instrument is a new measuring instrument that can realize angle measurement and distance measurement at one time. However, this specific function formerly can only be achieved by using a theodolite with a steel rule or range finder. The angle measurement system of the engineering surveying instrument adopts the absolute code technology, so that the angle can be measured to a high accuracy of 2". The ranging system adopts reflectorless laser ranging technology, with a ranging accuracy of 5mm and a long ranging distance of 100m. This surveying instrument also features large screen display, simple Operation and high cost performance. In addition, it is fully compliant with DIN18723 standard, so it is widely used in the engineering survey of mine, railway, water conservancy projects, and so on.
