PROVA5637記錄型鉗型接地電阻計(jì)/PROVA-5637
產(chǎn)品概述
PROVA5637記錄型鉗型接地電阻計(jì)是一款采用非接觸式測量技術(shù)的專業(yè)測試儀器,適用于各類接地系統(tǒng)的快速檢測。該產(chǎn)品通過創(chuàng)新設(shè)計(jì)實(shí)現(xiàn)了傳統(tǒng)測量方式的效率提升,測量時間僅需傳統(tǒng)方法的1/10,在100Ω范圍內(nèi)測量準(zhǔn)確度可達(dá)2%。儀器采用鉗形結(jié)構(gòu)設(shè)計(jì),無需輔助電極棒即可完成測量,大大簡化了現(xiàn)場操作流程。135
技術(shù)特點(diǎn)
PROVA-5637具備0.025-1500Ω的寬范圍電阻測量能力,并集成0.2mA-35A交流電流測量功能。其獨(dú)特的大口徑鉗部設(shè)計(jì)(最大開口38mm/Φ35mm)可輕松夾持各類接地導(dǎo)線。儀器配備116組數(shù)據(jù)存儲容量,支持可編程上下限設(shè)定和超限報警功能,當(dāng)測量值超出設(shè)定范圍時會自動發(fā)出蜂鳴提示。4+4位LCD顯示屏可直觀讀取測量數(shù)據(jù)和記錄信息,用戶還可設(shè)定1-255秒的自動記錄間隔。268
應(yīng)用領(lǐng)域
This clamp-on ground resistance tester is widely used in power equipment grounding, lightning rod grounding, telecommunication base station grounding, and industrial facility grounding systems. It is particularly suitable for oil depots, mining sites, cable TV networks and other scenarios where traditional measurement methods are difficult to implement. The built-in standard resistance calibration plate ensures measurement reliability in various field conditions.3912
操作特性
The PROVA5637 features user-friendly operation with automatic ranging function and low power consumption (40mA). Its ergonomic design includes a portable carrying case and operates on 9V alkaline battery with approximately 3000 measurements per battery life. The instrument maintains stable performance within 0°C to 50°C operating temperature range, with compact dimensions of 276x100x47mm and lightweight body (750g including battery). Data can be directly read from the backlit LCD display or reviewed through the memory recall function.51317
附加功能
該產(chǎn)品具有自動關(guān)機(jī)省電功能,在閑置約3分鐘后會自動關(guān)閉電源。測試頻率采用3.333KHz特殊設(shè)計(jì),有效避免工頻干擾。隨產(chǎn)品附贈標(biāo)準(zhǔn)電阻板、便攜箱、中英文使用手冊等配件,方便用戶現(xiàn)場使用。其創(chuàng)新的雙功能設(shè)計(jì)(接地電阻+漏電流測量)為電氣系統(tǒng)維護(hù)提供了全面的診斷工具,特別適合需要定期檢測的防雷接地系統(tǒng)和電力設(shè)施接地網(wǎng)絡(luò)。11115
