Product Description:
The DT-2 Optical Theodolite is an entry-level surveying instrument featuring a lightweight aluminum alloy body weighing 4.2kg. Its 40mm objective lens with anti-reflective coating ensures clear imaging even in moderate lighting conditions. The horizontal circle and vertical circle both provide 1-minute graduation accuracy through direct reading system.
Notable operational features include a two-speed tangent motion mechanism for precise targeting adjustment and a built-in optical plummet with ±3mm accuracy range. The instrument maintains stable performance within temperature range of -10℃ to +45℃, with IP54 dust/water resistance protecting internal components.
Practical design elements encompass a foldable carrying handle, universal tripod interface compatible with most 5/8" threaded mounts, and color-coded leveling screws for intuitive operation. The package includes a protective transport case, lens cleaning kit and user manual with trigonometric calculation reference tables.
Ideal for construction layout, preliminary land surveying and technical education, this cost-effective solution balances essential functionality with simplified maintenance requirements, making it particularly suitable for small contractors and vocational training institutions.
