ETCR2800KC Open/Close Type Ground Resistance Online Tester

Product Overview

The ETCR2800KC Open/Close Type Ground Resistance Online Tester is another high-tech product from Wuhan鄂Electric Power Test Equipment Co., Ltd., which has been committed to "ground resistance testing technology research" for many years. It is meticulously designed and manufactured for online monitoring the connection status of grounding conductors, loop ground resistance, and metal loop bonding resistance.

The ETCR2800KC Opening and Closing Type Ground Resistance Online Tester features an opening and closing structure, allowing for installation without disconnecting the grounding lead, ensuring convenience and speed. It supports online testing, non-contact measurement, ground wire passing through the center, without affecting lightning protection grounding effects or facility operation. No self-check required, with real-time detection, utilizing RS232, RS485 wired communication, or GSM wireless communication for data transmission, enabling remote online monitoring.

The ETCR2800KC Opening and Closing Ground Resistance Online Tester is equipped with built-in sensors and circuit boards, offering a fully enclosed design with features such as rainproof, dustproof, high and low temperature resistance, corrosion resistance, flame retardant, etc. It ensures high precision, stability, and reliability for long-term online monitoring in outdoor, underground mines, and indoor environments.

The ETCR2800KC model can directly display the measured value on an LCD and also set alarm threshold values through the tester, featuring audio-visual alarm indicators. It is particularly suitable for independent installation and use without the need for network setup.

The ETCR2800KC has passed the explosion-proof certification, complying with the requirements of GB3836-2000 "Electrical Equipment for Explosive Gas Atmospheres." Its explosion-proof marking is Ex ia ⅡB T3 Ga. The explosion-proof certificate number is CE13.2262X. It is suitable for use in corresponding flammable and explosive environments.
