Product Overview
The metal meter box body is mainly made of stainless steel material (304) or cold-rolled steel plate processing and forming. The box body has high temperature resistance, aging resistance, impact resistance, anti-corrosion, moisture-proof, waterproof, safe and reliable. The electrical metering device adopts a fully enclosed management, with functions such as closed metering circuit, prevention of electricity theft, and easy meter reading.
