Clamp-Style Digital Earth Resistance Tester
Products Description
Developed by the Technical Department of Huazheng Electric Manufacturing (Baoding) Co., Ltd., this instrument delivers significant performance enhancements, including:
Immediate start-up with no lengthy self-test waiting period, allowing tests to begin right away.
Advanced intelligent processing with digital integration technology, replacing traditional relay-based self-test methods.
Redesigned to be lightweight and compact, offering true handheld convenience.
Streamlined 6-button control panel for improved usability.
Audible and visual alarms with a distinct "beep-beep-beep" alert.
Added interference signal detection indicator.
Enhanced anti-interference capability and testing stability.
Data storage capacity: up to 99 units.
Broader measurement range: 0.01Ω to 1200Ω.
Lower power consumption: maximum operating current ≤ 50mA.
The HZRC Series Clamp Earth Tester is widely used for grounding resistance measurement across industries such as power supply, telecommunications, meteorology, oilfields, construction, and industrial electrical equipment.
It enables safe, fast, and simple measurement without disconnecting ground conductors or using auxiliary electrodes-especially in grounded systems with loop current.
Capable of diagnosing faults beyond the reach of traditional methods, the HZRC tester measures the combined resistance of the ground body and lead. Its elongated jaw design (as shown in the figure below) is ideal for flat steel grounding applications.
Additionally, the C+ Clamp Earth Tester can measure leakage current and neutral current in grounding systems.
