Absolute Encoder

The DJDM-1 absolute encoder adopts absolute coding angle measurement technology. It doesn't need to go through zero-crossing modulation when powered on, and can automatically save the angle values even when the power is turned off. Our absolute encoder is suitable for control surveying, and ensineering surveying in the field of mines, railways and water conservancy, as well as other professional mesurement on construction sites.

The electronic theodolite has big buttons, large-screen text display and user-friendly Operation interface. Our electronic theodolite can realize two-way communication with the PC, and comes with the function of clock display. The rechargeable battery with large capacity ensures ultra-long standby of the instrument. The application of online programmable technology also brings convenience for software upgrades.

With a fashionable and stable tribrach, our high quality electronic theodolite is ideally suited for fieldwork, and has found applications in control surveying, engineering surveying, topographic surveying and other professional surveying.
