902EN Total Station

The 902EN total station with IP66 protection grade is designed as per European standard, and offers superior dust and water proof performance. It is especially designed for use in bad working environments.

Designed based on absolute coding technology, it has one encoder for angle measurement and realizes absolute angle reading, and improved angle measurement performance. It eliminates the need for vertical angle initialization when it is powered on. Meanwhile, it can save the horizontal angle without re-orientation when it is powered off.

1. The total station uses a CCD as the receiver and incorporates a high-speed 32-bit CPU. Additionally, it features simple structure as well as high reliability and stability.
2. It supports reflectorless distance measurement.
3. It is available with a large LCD display screen with simple-designed number keys and letter keys. It can be equipped with a 2GB SD card.
4. Large capacity lithium battery ensures long operation time.
5. Visible laser indicator ensures faster and accurate aiming.
6. The product supports data transmission via RS232-C compatible asynchronous serial port.
7. The instrument integrates many measurement applications. It supports area calculation, as well as measurement of coordinate, subtense, suspension height, resection, and more.
