AEMC 4620 KIT-500 Ground Resistance Tester

Overview

The AEMC 4620 KIT-500 is a digital ground resistance tester for earth ground resistance and soil resistivity measurements. This direct-reading instrument features auto-ranging technology that automatically selects the optimal measurement range from 0 to 2000Ω. Designed for field crews performing numerous tests, it combines rugged construction with proven accuracy and ease of use.

Key Features

• Auto-ranging: automatically selects optimum measurement range
• Direct reading display with 0-2000Ω measurement range
• Measures ground resistance using 2-point and 3-point Fall-of-Potential methods
• Soil resistivity measurement using 4-point testing method
• Designed to reject high levels of electrical interference
• Exceeds IEC standards for shock, vibration, and drop testing
• Operable under difficult field conditions with high stray currents
• Battery powered for portable field deployment
• Rugged, dustproof and rainproof construction
