產品名稱:表面體積電阻率測試儀

產品型號:GHT-G

產品報價:

產品特點:表面體積電阻率測試儀 適用于科研、工廠、學校、企業部門對絕緣材料、橡膠、塑料、薄膜、及粉體、液體、及固體和膏體形狀的各種電工產品、電子設備以及元件的絕緣測量和高阻值兆歐電阻的測量也可用著微電流測量,是一種直讀式和微電流兩用儀器。

GHT-G表面體積電阻率測試儀的詳細資料:

表面體積電阻率測試儀是根據:GB/T 1410-2006《 固體絕緣材料體積電阻率和表面電阻率試驗方法》ASTM D257-99《絕緣材料的直流電阻或電導試驗方法》GB/T 10581-2006 《絕緣材料在高溫下電阻和電阻率的試驗方法》GB/T 1692-2008 、GB/T 2439-2001、GB/T 12703.4-2010 《紡織品  靜電性能的評定  第4部分:電阻率》GB/T 10064-2006《測定固體絕緣材料絕緣電阻的試驗方法》

GB /1672-1988 液體增塑劑體積電阻率的測定

3、顯 示 方 式:彩色觸摸屏顯示

4、內置測試電壓:0-1000V自動調節(可根據要求調節到需求電壓)

5、基本準確度:1% (*注)

6、使用環境: 溫度:0℃~40℃,相對濕度<80%

7、機內測試電壓:0-1000V 任意調節

8、供電形式: AC 220V,50HZ

主要優勢特點:

1.顯示方式:彩色觸摸屏操作、顯示,代替其它家液晶屏顯示、手動操作。

2.測量時間顯示準確確定試樣極化時間,使測量結果更加準確.

3.電阻測量范圍寬  0.01×104Ω ~1×1018Ω

4.電流測量范圍為 2×10-4A ~1×10-16

5.體積小、重量輕、準確度高

6.顯示數據:電壓、電阻、電流、電阻率

7.性能穩定好、自動計算,代替老款人工計算。

8.所測試電壓從0-1000V手動調節,是國內 一款連續可調電壓。市場上都是 10V/50V/100V/250V/500V/1000V固定檔位。

9.所有測試電壓0-1000V 測試時電阻結果直讀,免去老式高阻計在不同測試電壓下或不同量程時要乘以系數等使用不便的麻煩,使測量超高電阻就如用萬用表測量普通電阻樣簡便。

10.既能測超高電阻又能測微電流
