Product Introduction
The MOEORW-W1105 grounding resistance tester uses integrated circuits and DC/AC conversion technology to accurately measure grounding resistance, soil resistivity, conductor resistance, and AC ground voltage. It features strong anti-interference capabilities, automatic constant current, and no need for manual balancing. It is suitable for power, telecommunications, railway, communications, mining, and other scenarios, and is a dedicated instrument for electrical grounding system testing, lightning protection acceptance, and safety maintenance.

Product features and applications
- In terms of structure, high-strength aluminum alloy is used as the housing. In terms of circuit, a phase-locked loop synchronous tracking detection method is used to prevent power frequency and radio frequency interference, and a switched capacitor filter is added to give the instrument good anti-interference ability.
- DC/AC conversion technology is used to convert DC into low-frequency constant AC current for easy measurement.
- The auxiliary grounding resistance is allowed to vary between 0~2KΩ (RC) and 0~40KΩ (RP) without affecting the measurement results.
- This instrument does not require manual balancing and features a 3 (1/2) digit LCD display. In addition to measuring ground resistance, it can also measure the resistance of low-resistance conductors, soil resistivity, and AC ground voltage.
- If the test circuit is not open, the meter will display "1" to indicate an overflow, which is in line with standard measurement practices.
