SOUTH ET-02 Electronic Digital Theodolite – 2″ Accuracy

The SOUTH ET-02 Electronic Theodolite is a precision surveying instrument designed for accurate measurement of horizontal and vertical angles in construction, engineering, land surveying and other geospatial applications. It combines a 30× magnification telescope, absolute-encoding angle measurement system, dual-sided LCD displays and 2-arc-second angular accuracy, allowing surveyors and engineers to obtain precise angular measurements in the field. The telescope features a 45 mm effective aperture, 3″ resolving power and a minimum focusing distance of 1.4 m. Its automatic vertical compensator helps maintain accurate readings when minor instrument leveling variations occur. The ET-02 also provides internal storage for up to 256 pairs of horizontal and vertical angle measurements, making it useful for repetitive field surveying and construction-layout work.
