  • Versatile Digital Clamp Meter: Accurately measures AC/DC Current, AC/DC Voltage, Capacitance, Frequency, Duty Cycle, Resistance, Diode, Continuity and Live Wire Tests. This clamp meter is a really useful tool for solving industrial and household electrical issues.
  • Non-contact Voltage Testing: This Clamp Meter features non-contact voltage testing with sound and light alarms. When the Meter senses a weak AC signal, the green indicator light will come on and the buzzer will emit a slow, audible beep. when the Meter senses a strong AC signal, the red indicator light will come on and the buzzer will emit a brief beep
  • Multifunctional & Easy to read: Support Data Hold, Max/Min, Auto power off after 15 minutes inactivity, low battery indicator and continuity buzzer. The LCD Backlit Screen and Flashlight make it easy to use in a dark working area. ZERO function decreases the data error influenced by the Earth’s magnetic field, and helps you to obtain a more accurate measurement.
  • Large Jaw Opening: The jaw opening measures current in a conductor without touching or interrupting the circuit. Its slim and compact size makes it easy to operate in narrow spaces.
  • Safety and Service: This clamp meter has passed the environmental pollution test degree 2 and overvoltage category III 600V safety standards. Please feel free to contact us if you have any problems.

Note: To measure the current you need to clamp the meter around one of the wires and not the whole power cord. The power cord contains two wires carrying the current and ground wires. The current in two wires always flows in opposite directions, so the magnetic fields from two wires cancel each other, therefore the meter reads 0 A


The NCV function can test the voltage without contact. When the Meter senses a weak AC signal, the green indicator light will be on and the buzzer will emit a slow, audible beep. When the Meter senses a strong AC signal, the red indicator light will be on and the buzzer will emit a brief beep.

AstroAI 4000 Counts TRMS Clamp Meter

The AstroAI True RMS 4000 Counts Digital CLAMP METER is designed to be safely and accurately used by professionals and weekend DIYer’ s.

It is suitable for commercial and household electrical problems. Advanced features have been provided including AC/DC Voltage, AC/DC Current, Frequency, Duty Cycle, Resistance, Capacitance Measurement and NCV Detection, Flashlight, Diode, Live Wire Test and Audible Continuity Testing.

  • Detects Live Wires

    Live wire testing with the red test lead. This unique function tests the presence of live wires. When it detects a live wire, the multimeter will reflect with the audio alarm.

  • Frequency and Duty Cycle Test

    Turn the rotary dial to the “Hz/%” setting (Duty Cycle Test: Please press the FUNC button to duty cycle test.) The screen will display “ HZ/% ” indicating the measurement function.

  • Test AC/DC Voltage, AC/DC Current, Resistance, Capacitance etc.

    The CM4KOR Clamp Meter can accurately measure AC/DC Voltage, AC/DC Current, Resistance, Capacitance etc.

  • Zero Function

    This function helps decrease the data error influenced by the Earth’s magnetic field, and helps you to obtain a more accurate measurement.

  • Backlit LCD and Flashlight

    The Backlit LCD and Flashlight ensure clear measurements in a dimly lit area. The Backlight can be switched manually and shuts off automatically after 15 minutes.

  • Continuity Test

    Connect test leads to the circuit, the buzzer inside the Meter will beep if the resistance<50Ω.

  • Correct Measurement

    Please measure in the correct way, otherwise the readings will not be accurate.

  • NCV Detection

    This multimeter features non-contact voltage testing with a sound and light alarm. When the indicator light is on, it means there is voltage, please pay attention to your safety.
