PRODUCT DETAILS
LDT-302 Electronic Digital Theodolite Feature:
Precision Angle Measurement with Advanced Technology
The LDT-302 Electronic Digital Theodolite features an absolute encoder and 1"/5" minimum reading resolution, delivering exceptional accuracy for complex surveying tasks. Its dual-axis compensation ensures reliable measurements even on uneven terrain.
High-Performance Telescope with Clear Imaging
Equipped with a 30x magnification erect telescope and 45mm objective aperture, the LDT-302 Digital Theodolite provides sharp, distortion-free imaging. The 3" resolution and 1°30' field of view enable precise targeting over long distances.
Integrated Laser Plummet for Easy Setup
Streamline your fieldwork with the built-in Class II laser plummet in the LDT-302 Theodolite, offering 1mm accuracy at 1.5m. The red beam (635nm) ensures quick and accurate point transfer for efficient operation.
Robust Design and Versatile Functionality
Designed for harsh environments, the LDT-302 Electronic Digital Theodolite operates in -20°C to +50°C conditions. With RS232C data output and 1000-point memory, it seamlessly integrates into modern surveying workflows.
User-Friendly Operation with Enhanced Visibility
The dual-face LED backlight display of the LDT-302 Digital Theodolite guarantees clear readability in all lighting conditions. Its detachable tribrach and NiMH battery system support extended use in remote locations.
