Huazheng HZRC-2100C Ground Resistance Clamp Meter
Huazheng HZRC-2100C Ground Resistance Clamp Meter
The earth resistance meter is a specialized instrument designed for measuring grounding resistance and low-resistance conductors. It is widely used across power utilities, postal services, railways, telecommunications, mining, and other industries.
Key Performance Improvements
Instant Startup – Traditional instruments often require lengthy self-test procedures upon power-on. This meter eliminates that delay, entering test mode immediately for faster field deployment.
Intelligent Relay Self-Test – Leveraging advanced processing algorithms and digital integration technology, the instrument performs intelligent relay self-tests that are both comprehensive and efficient.
Lightweight Design – Significantly lighter than previous-generation products, the meter is ideally suited for handheld use in field environments.
User-Friendly Interface – The panel features six buttons for intuitive operation, enhancing overall user experience.
Audible and Visual Alarm – An integrated sound and light alarm provides clear alerts with a distinctive "beep-beep--beep--" tone.
Interference Signal Indicator – A dedicated indicator alerts the user to the presence of interference signals, helping to ensure measurement integrity.
Enhanced Anti-Interference – Improved anti-jamming capability delivers superior test stability in electrically noisy environments.
Data Storage – The instrument can store up to 99 sets of test data for later review and analysis.
Low Power Consumption – With a maximum operating current of no more than 50 mA, the meter offers extended battery life for prolonged field use.
