Electronic Theodolite ETH-300 Series

   Features
Adopting LLV green environmental protection body, can be seen under low lighting with peaceful and quite feeling.

Excellent optical system make instrument with very good view effectivity under low light condition.

Simple operation keyboard, water protective design, 6 keys make abundant functions.

Electronic incremental diameter angle measurement, 1¡å and 5¡å and 10¡åminimum display.

Convenient attachable handle design, make instrument can be connected with various EDMs and data communication.

Crystal board with 2 lines dot-matrix displays horizontal, vertical angles, slop percentage , battery volume and Slop distance, height difference.

Standard RS232 data interface can be connected with PC or electronic field books

ETH electronic theodolite adopted 2 Ni-H batteries with low memory, big electrical volume can be used continuously up to 12 hours. Charger with auto-discharge, charge and disconnect functions, make battery under optimum status.

Auto-compensation makes instrument auto-leveling within 3¡å and 1¡å accuracy.
