The AEMC 3620 analog ground resistance tester performs ground resistance measurements from 0.5 to 1000Ω with speed and accuracy. The 3620 features three-terminal operation for Fall-of-Potential earth/ground resistance and also may be used for 2-Point tests. The 3620 is the ideal instrument for electrical contractors, power utilities, REAs, telephone and inspectors who must check ground to determine compliance with NED, OSHA and other specifications.

The large 3.1" logarithmic analog scale is easy to read and includes separate markings for 25 Ω. A large Press-to-Measure button allows for easy measurements. A manual zero adjust is provided for accurate readings. Color-coded binding post terminals are easy-to-use with banana plug and spade lug inputs.

The heavy duty ABS case is O-ring sealed against dust and water, and the Press-to-Measure button is also sealed. The ground tester 3620 is battery powered for convenient use in remote field applications. Mechanical and safety specifications, such as vibration and drop test, meet or exceed IEC standards, to ensure safe and reliable field use.

The AEMC Model 3620 Ground Resistance Tester ships complete with soft carrying case, batteries and user manual. The AEMC Model 3620 is also available in multiple kit configurations.
