AC/DC Clamp Multimeter – Resistance, Frequency, Duty radio, Capacitance, Diode, NCV and Portable AC/DC Voltage & Current Tester with Auto-Ranging and Data Hold Functions

NOYAFA NF-6304 AC/DC Clamp Multimeter

NOYAFA NF-6304 is a multifunctional digital clamp multimeter designed to measure key electrical circuit parameters. It supports AC and DC current, AC and DC voltage, resistance, frequency, duty cycle, capacitance, and temperature measurements. The device also features diode testing, audible continuity testing, and NCV non-contact voltage detection.

The clamp jaws have a maximum opening of 26 mm, allowing current measurements to be performed without disconnecting or breaking the circuit. The clamp design is suitable for wires of different sizes and makes electrical testing more convenient.

True RMS technology provides accurate measurements for different waveforms, including non-sinusoidal signals. The LCD shows up to 5,999 counts, while the display and work-area illumination make readings easier to see in low-light conditions.

The NCV function detects AC voltage and electromagnetic fields without direct contact with the conductor. When voltage is detected, the multimeter provides an audible alert. During continuity testing, the buzzer and indicator light activate when the resistance is below 50 Ω.

For convenient operation, the multimeter features automatic range selection and a data hold function that keeps the current reading on the display. The device automatically switches off after 15 minutes of inactivity.

The multimeter housing features a shock-absorbing structure and 360-degree anti-vibration protection designed to help protect the device from impacts and drops.
