【Product Introduction in English】
The SF2678A Digital Ground Resistance Tester is a professional-grade electrical safety inspection device developed for power systems, communication base stations, industrial facilities, and building grounding projects. It delivers efficient performance evaluation and maintenance services for grounding systems through advanced digital signal processing technology and intelligent operation design.
Equipped with a 30A high-current output module, this instrument effectively overcomes measurement limitations in complex soil environments, significantly enhancing anti-interference capabilities. The wide measurement range of 0-20Ω with 0.001Ω resolution ensures precise detection of subtle resistance variations. The 6.5-inch high-definition LCD screen displays real-time data curves and supports measurement value hold function, enabling rapid on-site data interpretation.
Featuring industrial-grade protection (IP54 rating), the device operates reliably within -20℃ to 50℃ temperature range. Its auto-recognition function for three-wire/four-wire measurement modes simplifies operation procedures, while the intelligent alarm system promptly indicates wiring anomalies or out-of-limit values, ensuring operational safety. The built-in high-capacity lithium battery supports 8 hours of continuous operation, combined with a portable carrying case design, making it ideal for field applications.
This instrument demonstrates excellent environmental adaptability, maintaining measurement accuracy even under strong electromagnetic interference. Its humanized interface design and multilingual menu options provide convenient operation experience for global users across diverse industries.
