【Professional Clamp Meter】 Quickly and safely measures AC/DC current (up to 600A), AC/DC voltage (up to 600V), resistance (60MΩ max), capacitance (6mF max), frequency (10MHz max), duty cycle, continuity, and diode. Built-in NCV detection (48–250V) and live wire (110–380V) with audible alarm. Crenova clamp meter is ideal for electricians, HVAC, and industrial maintenance.

【More Advanced Functionality】 Supports inrush current (INR) measurement, temperature from -4°F to 1832°F (with K-type probe), and LowZ mode to eliminate ghost voltage false readings. V.F.C (Variable Frequency Carrier) filter ensures stable readings on variable-frequency drives. This electrical tester can handle more complex problems in professional/industrial use.

【25mm Jaw Opening 】 The clamp jaw fits wires up to 25mm in diameter, so the amp meter is suitable for most circuit measurements in home or industrial use. Please note: The clamp jaw is designed SOLELY for current measurement. And when measuring, clamp it around ONE wire only (not the entire cable or whole power cord).

【User-Friendly Design】Includes 6000-count LCD, data hold, relative (REL) mode, zero function(DC current), backlight, bright torch, low battery indicator, and auto power off, the true RMS digital multimeter is a perfect tool for household, automotive, industrial, laboratory and office electrical inspection, maintenance and repairs.
