Product Introduction
- The DT-02L electronic theodolite is widely used for national and municipal third- and fourth-order triangular control surveys. It applies to engineering surveys for railways, highways, bridges, water conservancy projects, mines and other fields, as well as construction work and installation of large-scale equipment. It can also be adopted for cadastral surveying, topographic surveying and various engineering quantity measurements.
- Extra-large LCD screen for easy reading and user-friendly operation;
- Absolute encoding angle-measuring system;
- High-stability electronic compensator;
- Multiple measurements of the same angle can be averaged to improve accuracy and reduce recording work.

Product Feature And Application
No calibration required for the laser
- The lower laser is installed on the vertical spindle.This structural design prevents laser spot deviation and ensures high precision of the lower laser point.
Encoder-based angle measurement technology
- No initialization required upon startup; angle data is automatically saved when the device is turned off
- No need to worry about data loss even if the device is turned off due to a power outage during extended outdoor use
