EM-JDT指針式接地電阻測試儀 產(chǎn)品介紹
產(chǎn)品概述
EM-JDT指針式接地電阻測試儀是一款專為測量接地系統(tǒng)電阻值設(shè)計的機(jī)械式檢測設(shè)備，適用于電力系統(tǒng)、通信基站、建筑工地、防雷設(shè)施等多種場景的接地性能檢測。該產(chǎn)品采用經(jīng)典指針表盤設(shè)計，結(jié)合雙量程測量功能，能夠直觀反映接地電阻變化趨勢，為工程安全提供可靠數(shù)據(jù)支持。
核心優(yōu)勢
- 穩(wěn)定可靠：機(jī)械指針結(jié)構(gòu)無電子元件漂移風(fēng)險，抗電磁干擾能力強(qiáng)，在復(fù)雜工況下仍能保持測量穩(wěn)定性。
- 直觀易讀：270°廣角表盤搭配高靈敏度指針，支持快速讀取0.1Ω至2000Ω范圍內(nèi)的電阻值，紅黑雙色刻度區(qū)便于識別安全閾值。
- 環(huán)境適應(yīng)：內(nèi)置阻尼防震系統(tǒng)可有效減少現(xiàn)場震動影響，寬溫型設(shè)計（-20℃~+50℃）適應(yīng)戶外惡劣環(huán)境。
- 雙模式測量：通過旋鈕切換0-20Ω（高精度模式）和0-2000Ω（寬域模式），滿足不同接地系統(tǒng)的檢測需求。
- 操作便捷：一體化機(jī)身設(shè)計配備防滑握柄，三接線柱標(biāo)識清晰，支持單手操作完成測試流程。
