Kelida DT-02cl Electronic Theodolite

Kelida DT-02CL Chinese ElectronictheodoliteIt is a regular infrared meridian with absolute coded reading, displayed in Chinese, angle measurement accuracy of 2 seconds, electronic bubble compensation accuracy of 1 second, compensation range: ± 4 ′. Equipped with laser centering device. Optimization design of resistance reduction circuit, internationally pioneering CCD as receiver.

The laser and the host share the same battery, with an integrated design
● Adopting double-sided LCD Chinese display, convenient, fast, practical, and accurate
Liquid electronic sensor that can compensate for vertical axis tilt at any time to ensure accurate readings
Horizontal and vertical discs use diameter readings to ensure a 2-second accuracy

Long lasting batteries can work continuously for 10 hours
