UT258A+ 20mm AC/DC LEAKAGE CURRENT CLAMP
The UT258A+ is a professional AC/DC leakage clamp meter for electricians in data centers, commercial buildings, and renewable energy plants. It detects both AC and DC leakage—unlike AC-only meters—making it ideal for solar farms, DC UPS, and EV charging. With True RMS, Bluetooth remote monitoring, and CE/cETLus certification, it’s a reliable tool for leakage troubleshooting and preventive maintenance in mixed AC/DC environments.
