中文版：
J2-2光學(xué)經(jīng)緯儀是一款專為工程測(cè)量與地形測(cè)繪設(shè)計(jì)的精密光學(xué)儀器，憑借其可靠的測(cè)量性能與人性化設(shè)計(jì)，成為建筑、地質(zhì)、交通等領(lǐng)域?qū)I(yè)工作者的理想選擇。該產(chǎn)品采用優(yōu)質(zhì)光學(xué)玻璃鏡片組，配合精密機(jī)械傳動(dòng)系統(tǒng)，可實(shí)現(xiàn)水平角與垂直角的高精度測(cè)量，滿足多種復(fù)雜工況下的作業(yè)需求。
核心功能方面，儀器配備高分辨率光學(xué)讀數(shù)系統(tǒng)，最小顯示精度達(dá)1"，配合雙向微動(dòng)螺旋調(diào)節(jié)裝置，操作者可輕松完成目標(biāo)對(duì)準(zhǔn)與數(shù)據(jù)讀取。獨(dú)特的防震結(jié)構(gòu)設(shè)計(jì)有效降低環(huán)境震動(dòng)對(duì)測(cè)量結(jié)果的影響，內(nèi)置干燥倉系統(tǒng)可防止鏡片起霧，保障設(shè)備在-20℃至+50℃環(huán)境下穩(wěn)定運(yùn)行。為提升操作便利性，儀器主體采用輕量化鎂合金框架，標(biāo)配便攜式三腳架適配器，整機(jī)重量較同類產(chǎn)品減輕約15%，特別適合野外長(zhǎng)時(shí)間作業(yè)。
本產(chǎn)品適用于道路勘測(cè)、水利工程布設(shè)、建筑物軸線定位等多種場(chǎng)景，標(biāo)配可拆卸式激光對(duì)中器（選配），顯著提升對(duì)中效率。售后服務(wù)方面，我們提供全國(guó)范圍內(nèi)的技術(shù)咨詢、設(shè)備校準(zhǔn)與零部件更換服務(wù)，購買即享三年核心部件質(zhì)保。
現(xiàn)推出限時(shí)尊享計(jì)劃：批量采購可獲專屬定制化解決方案，單臺(tái)訂購享免費(fèi)操作培訓(xùn)及儀器保養(yǎng)套裝。歡迎通過官網(wǎng)或授權(quán)經(jīng)銷商獲取詳細(xì)技術(shù)參數(shù)與地區(qū)優(yōu)惠方案。
English Version:
The J2-2 Optical Theodolite is a precision-engineered surveying instrument designed for engineering measurement and topographic mapping applications. With its dependable performance and user-centric design, it has become an essential tool for professionals in construction, geology, and transportation sectors.
Featuring high-grade optical glass lens assemblies and precision mechanical transmission systems, this instrument delivers accurate horizontal and vertical angle measurements with a minimum display resolution of 1 arc-second. The bidirectional fine-motion adjustment mechanism ensures smooth target alignment and data reading. Its innovative shock-absorbing structure effectively minimizes environmental vibration interference, while the integrated desiccant chamber prevents lens fogging, maintaining stable operation within -20℃ to +50℃ temperature ranges.
The lightweight magnesium alloy frame reduces total weight by approximately 15% compared to conventional models, complemented by a portable tripod adapter for enhanced field mobility. The optional detachable laser plummet accessory significantly improves centering efficiency, making it ideal for road surveying, hydraulic engineering layout, and architectural axis positioning.
We provide comprehensive technical support including nationwide calibration services and component replacement. All units come with a three-year warranty covering core mechanisms.
Special promotion available: Volume purchasers receive customized service packages, while individual orders include complimentary operation training and maintenance kits. Contact authorized distributors or visit our official website for technical specifications and regional offers.
