表面電阻檢測  740-行動條碼QR Code

袖珍740SRM表面電阻檢測器用於快速和可重複的測量導電、防靜電及絕緣表面的電阻率

* 740測量表面電阻率和接地電阻。

* 740採用ASTM標準D257方法。

* 表面電阻率測量-放在平坦的表面,按下按鈕不放。LED顯示十進制歐姆/平方米測量值。

* 與地面電阻測量-接地連接器與大地連接,按下按鈕,讀數即為物體與地面間電阻。

* CE認證。

The 740 Surface Resistance Checker is a pocket-sized instrument providing fast and repeatable measurements of conductive, static dissipative and insulative surfaces.

 

The 740 measures both surface resistivity and resistance to ground.

 

•It uses the ASTM Standard D257 method of parallel barsensing.

•For surface resistance, place the 740 on the flat surface to be measured, press the button and hold. The LED that illuminates is the decade measured in ohms/square.

•For resistance to ground measurement, insert the ground ,cord connector into the metal socket on the right hand side of the body. Then connect the crocodile clip to earth and, place the 740 on the surface to be tested. Press the button—the reading is resistance to ground in Ohms.

•Automatic ranging.

•Supplied with carrying case, battery and earth lead.

•CE Certified.740 measures both surface resistivity and resistance to ground.
