Digital ground resistance tester CA6462 @CA6462%
Digital ground resistance tester CA6462, formeasurement of grounding resistance and soil resistivity.Grounding resistance measurement range of 0 to 2000 Omega, the automatic range design, automatically switch to the best measurement range. Rugged CA6462 housing, simple operation, can be a variety of measurement, is the ideal choice for electricalmaintenance personnel. The mechanical index and safety index (such as: impact test, vibration test, drop test etc.)conforms to the IEC standard. Because of the high anti-interference design, which is suitable for various complex and bad environment (such as the existence of the effect of high stray current measurement accuracy). CA64629.6V, 3500 mAh Ni MH rechargeable battery power supply (NiMH), built-in charging circuit, can access120/230V 50/60Hz alternating current, the charging process of measuring sustainable.
