ETCR Earth Resistance Tester ETCR3000B with FFT AFC Technology

Description

Product Overview

The ETCR Earth Resistance Tester model ETCR3000B is a compact, portable instrument designed for accurate measurement of earth resistance, soil resistivity, and earth voltage. It supports 2‑wire, 3‑wire, and 4‑wire testing methods, covering ranges of 0.00Ω‑30.00kΩ for resistance, 0.00Ωm‑9000kΩm for resistivity, and AC 0‑600V for voltage. Advanced FFT (Fast Fourier Transform) and AFC (Automatic Frequency Control) technologies provide exceptional anti‑interference performance, ensuring reliable data in electrically noisy sites. The device features a large LCD with white backlight and a bar‑chart indicator for clear reading in low‑light conditions. Powered by six C batteries (included), it stores up to 300 data sets and offers USB connectivity for easy data transfer and reporting.

Usage

Ideal for electricians, field engineers, construction supervisors, and industrial maintenance teams, this tester excels in power plant grounding checks, building site earth‑grid verification, and agricultural soil analysis. Its rugged design tolerates field conditions, while the intuitive interface allows quick setup on job sites, substations, or remote locations. The USB port enables real‑time monitoring and integration with reporting software, streamlining compliance documentation and preventive maintenance programs.
