Total Station

Our 802ER total station can realize fast, remote and stable distance measurement. Due to the high-capacity lithium battery, it can also work as long as twenty hours for angle measurement. The total station has a large internal memory that can store 50000 points of data. By simulating windows file system resource manager, the data measured can be easily and well managed. The real-time and two-way data communication also enables the user to directly control the total station through programming on a computer.

Because of the excellent performance and various configurations, our total station sells well in the domestic and overseas market, and is widely used in engineering surveying, teaching and training, precision industrial installation, construction and many other areas. This instrument can also be equipped with a laser plummet.

Features of the Total Station
1. The total station can be pre-installed with a variety of application programs for layout measurement , area calculation, and accurate measurement of coordinate, suspension height, resection, subtense, eccentricity, angle measurement , etc. What's more, customized application software is also available.
2. This surveying instrument has a high density and large screen display. It is designed with alphanumeric key, function key and navigation key for easy and quick Operation. In addition, the key can also be freely defined to meet customers' different measurement needs.
