English Introduction
The PENTAX ETH-502 Electronic Theodolite is a high-precision surveying instrument that integrates optical, mechanical, and electronic technologies. It offers an angular measurement accuracy of 2 seconds, which is suitable for high-precision engineering surveys. The instrument features a dual-sided LCD display that can show both horizontal and vertical angles simultaneously. Even in low-light conditions, the readings remain clear.
The ETH-502 is equipped with a user-friendly keyboard that supports various functions, including arbitrary angle zeroing, angle setting out, angle measurement, and angle locking. Additionally, it has a robust waterproof design that allows it to operate reliably in adverse weather conditions. The PENTAX ETH-502 Electronic Theodolite is widely used in national and urban third and fourth-order triangulation surveys, as well as in engineering surveys for railways, highways, bridges, water conservancy, and mining.
