尼康NA730系列水準(zhǔn)儀產(chǎn)品介紹（中英雙語(yǔ)）
【中文部分】
尼康NA730系列水準(zhǔn)儀是一款專為工程測(cè)量領(lǐng)域設(shè)計(jì)的高性能光學(xué)儀器，適用于建筑施工、道路勘測(cè)、土地平整等多種場(chǎng)景。該產(chǎn)品憑借穩(wěn)定的測(cè)量精度和人性化操作體驗(yàn)，為專業(yè)測(cè)量人員提供可靠的數(shù)據(jù)支持。
在光學(xué)性能方面，NA730系列采用多層鍍膜物鏡系統(tǒng)，有效提升透光率至92%以上，確保在強(qiáng)光逆光環(huán)境下仍能保持清晰視野。30倍放大倍率配合42mm大口徑物鏡，可在100米距離范圍內(nèi)實(shí)現(xiàn)精準(zhǔn)讀數(shù)。分劃板采用高對(duì)比度刻劃工藝，特有的水平氣泡靈敏度達(dá)到10 /2mm，顯著提升調(diào)平效率。
設(shè)備結(jié)構(gòu)采用全密封防塵設(shè)計(jì)，內(nèi)部充填干燥氮?dú)�，有效防止水汽凝結(jié)。金屬與工程塑料復(fù)合機(jī)身經(jīng)過(guò)抗沖擊測(cè)試，可在-20℃至+50℃環(huán)境中穩(wěn)定工作。符合人體工學(xué)的水平微調(diào)旋鈕，配合阻尼適中的調(diào)焦手輪，使單手操作更加流暢。內(nèi)置可拆卸式太陽(yáng)濾光鏡，有效應(yīng)對(duì)強(qiáng)烈日照條件下的觀測(cè)需求。
該系列產(chǎn)品特別注重使用細(xì)節(jié)優(yōu)化：360度全向水平度盤便于快速定位，三腳架連接機(jī)構(gòu)采用快裝設(shè)計(jì)，轉(zhuǎn)換工作點(diǎn)位效率提升40%。標(biāo)配可更換式鋰電池組支持連續(xù)工作30小時(shí)，兼容通用USB充電接口。防滑橡膠握把與目鏡屈光度調(diào)節(jié)環(huán)的協(xié)同設(shè)計(jì)，兼顧不同使用者的操作習(xí)慣。

The Nikon NA730 Series Level is a high-performance optical instrument designed for engineering measurement applications, including construction projects, road surveying, and land grading. With its reliable measurement accuracy and user-friendly design, this instrument provides dependable data support for professional surveyors.
Featuring multi-coated objective lens system, the NA730 series achieves over 92% light transmittance, ensuring clear visibility even under strong backlight conditions. The 30x magnification combined with a 42mm large-aperture objective lens enables precise reading within 100 meters. The high-contrast reticle and sensitive leveling bubble (10 /2mm) significantly improve leveling efficiency.
Constructed with fully sealed dust-proof housing filled with dry nitrogen, the instrument effectively prevents internal condensation. The metal-reinforced composite body has passed impact resistance tests, maintaining stable performance in temperatures ranging from -20℃ to +50℃. Ergonomic leveling screws and optimally damped focusing wheel allow smooth one-handed operation. The detachable solar filter ensures comfortable observation under intense sunlight.
This series emphasizes operational refinement: The 360-degree horizontal circle enables rapid positioning, while the quick-release tripod adapter improves site relocation efficiency by 40%. The replaceable lithium battery supports 30 hours of continuous operation, compatible with universal USB charging ports. Non-slip rubber grips and adjustable eyepiece diopter cater to various user preferences.
With optimized weight distribution (1.8kg body weight) and compact storage case design, the NA730 series achieves an ideal balance between portability and functionality. Its broad application scope covers building layout, slope measurement, and infrastructure maintenance, delivering professional-grade measurement solutions for field operations.
