Product introduction
MEWOI7420 clamp multimeter is a portable clamp digital multimeter, which can measure DC voltage, AC voltage and current true RMS, resistance, frequency, continuity test, temperature, diode forward voltage drop and other parameters, and the capacitance measurement range is expanded to 10mF And the measurement of large capacitance is fast. The instrument is compact in structure, easy to operate and portable, and is an ideal tool for electrical measurement. It provides a safe, accurate and convenient new power meter for electricity inspectors, and is an essential tool for electrician safety inspection. |
