Product Introduction
The MOEORW-WRD21 explosion -proof clamp-on grounding resistance meter is widely used for measuring grounding resistance and loop resistance in power, telecommunications, meteorology, oil fields, construction, and industrial electrical equipment. When measuring grounding systems with loops, it is safe and fast because it does not require disconnecting the grounding lead or auxiliary grounding electrode. It can measure grounding faults that cannot be measured by traditional methods and can be applied to situations where traditional methods are inaccessible, because the ME2000B explosion-proof clamp-on grounding resistance meter measures the combined value of the grounding electrode resistance and the grounding lead resistance.
The MOEORW- WRD21 explosion- proof clamp-on grounding resistance meter meets the relevant requirements of GB/T 3836.1-2021 and GB/T 3836.4-2021 standards for its explosion-proof certification parameters. Its explosion-proof marking is Ex ia Ⅱ BT3Ga. Explosion-proof certificate number: CE23.3879. It can be used in appropriate flammable and explosive environments.
