EITAI3040 Digital Earth Resistance Meter delivers ultra-precise 0.01Ω-resolution measurement from 0.10Ω to 2000Ω, automatic wire resistance compensation, auxiliary ground rod judgment, a lightweight 470g field-ready design, and industrial-grade ABS durability with a backlit LCD, ensuring accurate and reliable operation in demanding environments.

Ultra-Precision Ground Resistance MeasurementThe EITAI3040 Earth Resistance Tester measures from 0.10Ω to 2000Ω with a resolution of 0.01Ω, making it ideal for low-resistance critical systems. It also accurately measures AC voltage up to 300V with 1V resolution. Equipped with an excellent anti-interference design, the device ensures stable performance even in challenging environments.

Automatic Wire Resistance CompensationOur advanced technology corrects errors caused by poor test lead contact or extension cords, guaranteeing high precision in on-site measurements.

Auxiliary Ground Rod Judgment The earth tester features a built-in auxiliary ground rod judgment function, which enhances the accuracy of field ground resistance measurements.

Lightweight & Field-Ready DesignWeighing just 470g, the compact main unit of this ground resistance tester is highly portable. Its top-mounted interface, vertical handheld form factor, and simple rotary knob enable user-friendly and intuitive operation.

Industrial-Grade Durability Constructed from ABS material for enhanced durability and moisture resistance, this device also features a backlight LCD display that remains easily readable under all lighting conditions, ensuring reliable performance in demanding work environments.
