AC/DC Digital Clamp Meter, Auto-Ranging 400 Amp

AC/DC Digital Clamp Meter, Auto-Ranging 400 Amp – True RMS Electrical Tester The Klein Tools CL390 is a professional-grade, auto-ranging digital clamp meter designed for precise electrical measurements in residential, commercial, and light-industrial environments. It provides true root mean square (TRMS) measurement technology, enabling accurate AC/DC current readings up to 400 amps via the clamp. This versatile meter also measures AC/DC voltage, DC microamps, resistance, continuity, frequency, capacitance, diode testing, and temperature with a thermocouple probe. Its reverse contrast LCD display ensures optimal visibility in both bright and low-light conditions, making it suitable for electrical distributors, lighting solutions providers, wire and cable specialists, and switchgear suppliers requiring reliable diagnostics and testing tools.
