產(chǎn)品概述
徠卡NA720自動(dòng)安平水準(zhǔn)儀是一款專為建筑測(cè)量、公路鐵路勘測(cè)、管道鋪設(shè)及隧道工程等常規(guī)高程測(cè)量設(shè)計(jì)的精密光學(xué)儀器。該儀器采用優(yōu)質(zhì)光學(xué)系統(tǒng)，配備20倍放大倍率望遠(yuǎn)鏡，即使在光線不足的拂曉、傍晚或建筑物陰影區(qū)域，仍能保持清晰成像，確保測(cè)量數(shù)據(jù)的準(zhǔn)確性。其創(chuàng)新補(bǔ)償器技術(shù)可在±15 范圍內(nèi)自動(dòng)安平，顯著提升作業(yè)效率。儀器符合人體工程學(xué)設(shè)計(jì)，雙側(cè)無限位螺旋便于快速瞄準(zhǔn)，50厘米短視距功能特別適合狹窄空間作業(yè)。146
核心特點(diǎn)
NA720水準(zhǔn)儀以堅(jiān)固耐用著稱，通過特殊密封工藝達(dá)到IP57防護(hù)等級(jí)，可抵御雨水、粉塵侵入，并能承受意外跌落或機(jī)械振動(dòng)沖擊，在惡劣環(huán)境下無需調(diào)校即可繼續(xù)工作。光學(xué)系統(tǒng)采用多層鍍膜鏡頭，有效減少眩光干擾，配合正像成像技術(shù)大幅降低視覺疲勞。儀器重量僅1.6kg，配合緊湊的160×140mm機(jī)身尺寸，兼具便攜性與穩(wěn)定性，適合長時(shí)間野外作業(yè)。2810
技術(shù)參數(shù)
該儀器每公里往返測(cè)高程精度為2.5mm，物鏡有效孔徑30mm，視場(chǎng)角1°20´，乘常數(shù)100。工作溫度范圍-20℃至+50℃，貯藏溫度可擴(kuò)展至-40℃至+70℃。圓水準(zhǔn)器靈敏度8 /2mm，配合粗瞄準(zhǔn)器可快速定位目標(biāo)。望遠(yuǎn)鏡采用充氮防霧設(shè)計(jì)，確保在濕度較大環(huán)境中正常使用。61216
應(yīng)用場(chǎng)景
廣泛應(yīng)用于房屋沉降觀測(cè)、市政工程高程控制、水利設(shè)施監(jiān)測(cè)等領(lǐng)域。在大型儲(chǔ)罐安裝、橋梁變形監(jiān)測(cè)等項(xiàng)目中表現(xiàn)突出，其穩(wěn)定性能有效減少因天氣因素導(dǎo)致的工期延誤。儀器操作界面簡(jiǎn)潔直觀，新手也可快速掌握基本測(cè)量方法，是工程團(tuán)隊(duì)理想的常規(guī)測(cè)量工具。41821
Product Overview
The Leica NA720 automatic level is a high-performance optical instrument designed for general construction surveys, road/railway profiling, and pipeline/tunnel elevation measurements. Featuring a 20x magnification telescope with premium multi-coated optics, it delivers sharp imaging even in low-light conditions at dawn, dusk, or shaded areas. The integrated compensator automatically levels within ±15 tilt range, significantly improving workflow efficiency. Its ergonomic design includes bilateral endless drives for fast targeting and 50cm short-distance measurement capability ideal for confined spaces.1610
Key Features
Renowned for ruggedness, the NA720 achieves IP57 protection against water/dust ingress and withstands accidental drops or mechanical vibrations without requiring recalibration. The optical system employs anti-glare coated lenses with erect image technology to minimize eye strain. Weighing only 1.6kg with compact dimensions (160×140mm), it balances portability with stability for extended field use. The nitrogen-filled telescope prevents internal fogging in humid environments.21217
Technical Specifications
This instrument provides 2.5mm elevation accuracy per km double-run, with 30mm objective lens diameter and 1°20´ field of view. Operating temperature ranges from -20℃ to +50℃, while storage tolerance extends to -40℃ to +70℃. The circular bubble offers 8 /2mm sensitivity, assisted by a coarse sighting notch for rapid object location. The 100x stadia ratio simplifies distance measurements.61619
Applications
Ideal for building settlement monitoring, municipal elevation control, and hydraulic structure inspections. Its reliability shines in projects like storage tank installations and bridge deformation surveys, minimizing weather-related downtime. The intuitive interface allows beginners to master basic operations quickly, making it a versatile tool for survey crews.42125
