【English Introduction】
The Suyi Optical J2-2 Theodolite is a high-precision optical instrument designed for professional measurement applications. Combining classic mechanical architecture with modern optical technology, it delivers reliable performance for engineering surveys, topographic mapping, and construction layout tasks.
Crafted from premium alloy materials through precision machining and multi-stage calibration, the instrument ensures smooth operation of mechanical axes with excellent environmental adaptability and long-term stability. The optical system features high light transmittance lenses that produce crisp images, supported by 30x magnification and a 5° wide field of view for clear target acquisition.
The laser-engraved reticle provides uniform scale markings, working in tandem with a sensitive micrometer to achieve angle measurement with 1" resolution. The telescope integrates rapid focusing knobs and diopter adjustment rings, accommodating users with varying visual acuity. Bidirectional reading windows on both horizontal and vertical circles enhance measurement accuracy through improved digital display technology.
Constructed with fully sealed dust-proof housing and shock-absorbing mechanisms, the instrument maintains stable performance within -20℃ to 50℃ temperature range. The forced centering device and optimized clamping system on the tribrach enable quick positioning and secure fixation. Weighing under 4.8kg with a detachable tripod, it balances portability and setup efficiency for field operations.
Suyi Optical s three-decade expertise in measurement instruments is reflected in J2-2 s meticulous craftsmanship: corrosion-resistant metal surfaces, long-life lubrication on rotating components, and ergonomically textured operation wheels ensure smooth handling even in humid or low-temperature environments. This theodolite serves as an essential tool for civil engineering, geological exploration, construction projects, and academic research, embodying reliable performance for professional surveyors.
