Megger DET 2/2 Auto Earth Tester Resistance Meter NIST Calibrated
The Megger DET2/2 Auto Earth Tester is a portable, high-accuracy instrument designed to measure earth (ground) resistance and soil resistivity for electrical systems. It uses a four-terminal (4-pole) testing method to eliminate measurement errors and ensure reliable results, even in challenging or high-noise environments.
Built for field use, it features a rugged, weather-resistant design (IP54), a large LCD display, and microprocessor-controlled operation with adjustable test frequency and filtering. This makes it ideal for testing large or complex grounding systems such as substations, industrial facilities, and utility installations.
