DIGITAL THEODOLITE 02-L

A digital theodolite is a surveying instrument used for measuring angles. Here’s a general overview of the specifications:
General Features:
Angle Measurement: Digital theodolites typically provide angular readouts in seconds of arc.
Display: They usually feature a digital display, often a dual-sided LCD, to show angle readings and other information.
Optical Plummet: Many digital theodolites include an optical plummet to help center the instrument precisely above the target point.
Power: They usually operate on rechargeable batteries or AA batteries and may have a long operating time.
Storage: Some models allow for data storage, often via a USB port or an SD card.
Ruggedness: They are designed to be rugged for field use, often with features like water and dust resistance.

Technical Specifications:
Magnification: The telescope magnification typically ranges from 20x to 30x.
Image: The image is usually erect (not inverted), meaning objects appear as they are in real life.
Field of View: The field of view through the telescope can vary, with a typical range of 1°30'.
Angle Measurement Accuracy: Accuracy can range from 1 second to 20 seconds, depending on the model.
Working Range: Theodolites are primarily used for measuring angles, not distances, so the "working range" is usually described in terms of the instrument's visibility to a target point.
Size and Weight: Theodolites come in various sizes and weights, with typical dimensions around 150-300mm and weights around 1-6 kg.
