徠卡NA2高精度自動(dòng)安平水準(zhǔn)儀是一款專為測(cè)量、工程和工業(yè)技術(shù)領(lǐng)域設(shè)計(jì)的精密儀器。它以其卓越的性能和廣泛的適用性，成為眾多測(cè)量任務(wù)的理想選擇。

該水準(zhǔn)儀具備高精度和專業(yè)化的測(cè)量能力，每公里往返測(cè)中誤差僅為0.7mm，配備GPM3平行玻璃板測(cè)微器時(shí)，精度可進(jìn)一步提升至0.3mm。其精密補(bǔ)償器能夠自動(dòng)安平視準(zhǔn)線，確保測(cè)量工作的快捷高效。此外，NA2采用無限位螺旋設(shè)計(jì)，操作更加方便，并結(jié)合粗、精調(diào)焦技術(shù)，使目標(biāo)成像清晰準(zhǔn)確。徠卡頂級(jí)的光學(xué)器件能夠有效減少人眼疲勞，即使在長時(shí)間使用下也能保持測(cè)量的準(zhǔn)確性和穩(wěn)定性。

在設(shè)計(jì)上，NA2采用了防霉、防震、防水的結(jié)構(gòu)，使其能夠在各種惡劣的環(huán)境條件下穩(wěn)定工作。其操作溫度范圍為-20℃至+50℃，儲(chǔ)藏溫度范圍為-40℃至+70℃，這使得它能夠適應(yīng)從極寒到極熱的各種氣候條件。

在應(yīng)用方面，NA2的用途極為廣泛。它可用于各等級(jí)水準(zhǔn)測(cè)量、高精度水準(zhǔn)測(cè)量、房屋沉降觀測(cè)，以及公路、鐵路、管道、隧道等常規(guī)高程測(cè)量和放樣。此外，它還可用于控制測(cè)量、視距測(cè)量和形變監(jiān)測(cè)，幾乎涵蓋了所有需要高精度測(cè)量的領(lǐng)域。

The Leica NA2 high-precision automatic leveling level is a precision instrument designed for measurement, engineering, and industrial technology fields. With its outstanding performance and wide range of applications, it has become an ideal choice for a variety of measurement tasks.

The NA2 boasts high-precision and specialized measurement capabilities, with a mean error of only 0.7mm for round-trip measurements per kilometer. When equipped with the GPM3 parallel glass plate micrometer, the precision can be further enhanced to 0.3mm. Its precision compensator can automatically level the line of sight, ensuring efficient and rapid measurement work. Moreover, the NA2 features an unlimited spiral design, which makes operation more convenient. Combined with coarse and fine focusing techniques, it provides clear and accurate target imaging. Leica s top-tier optical components effectively reduce eye fatigue, maintaining measurement accuracy and stability even with prolonged use.

In terms of design, the NA2 features a mold-proof, shock-resistant, and waterproof structure, enabling it to operate stably under various harsh environmental conditions. Its operating temperature range is -20℃ to +50℃, and the storage temperature range is -40℃ to +70℃, allowing it to adapt to climates ranging from extremely cold to extremely hot.

Regarding applications, the NA2 is extremely versatile. It can be used for all levels of leveling measurements, high-precision leveling measurements, and building settlement observations, as well as for conventional elevation measurements and layout in highways, railways, pipelines, tunnels. Additionally, it is suitable for control surveys, stadia surveys, and deformation monitoring, covering almost all fields that require high-precision measurements.
