리퍼비시 계측기
리퍼비시 계측기
전기 장비의 접지는 안전을 유지하고 생명을 보호하며 장비 손상을 방지하는 데 필수적입니다. 3151 접지 저항 테스터는 AC 위상 차동 시스템을 사용하여 접지 저항을 측정하므로 정확한 측정이 접지 전압 및 보조 접지 저항의 영향을 받지 않습니다.
Key Features
- Wide measurement range for 0 Ω to 1150 Ω, based on EN standard
- Semi-dust-proof construction
- Switchable measurement frequency to minimize the influence of harmonic earth voltage
