AEMC Instruments 4620 Ground Resistance Tester Kit, 300'

Product Highlights

The Digital Ground Resistance Tester Model 4620 performs earth ground resistance and soil resistivity tests. This direct reading tester measures from 0 to 2000Ω, and is auto-ranging, so it automatically seeks outs the optimum measurement range. The Model 4620 is rugged, easy-to-use and is ideal for maintenance crews performing numerous tests. It exceeds mechanical and safety specifications for shock, vibration and drop tests specified in IEC standards. It is designed to reject high levels of interference, so it can be used under difficult conditions such as high stray currents that normally affect accuracy.

• Ground Integrity Measurement
• Measures soil resistivity (4-Point)
• Measures ground resistance (2- and 3-Point) Fall-of-Potential method
• Step voltage tests and touch potential measurements
• Auto-Ranging: automatically selects the optimum resistance range and test current
• Designed to reject high levels of noise and interference
• Extremely simple to operate: connect/press/hold/read
• LED on faceplate informs operator of high input noise, high auxiliary rod resistance and faulty connections
• Large easy-to-read backlit display
