NEO TOOLS Digital Clamp Meter 400A AC/DC True RMS NCV 6000 Counts

When you need to measure current without breaking the circuit, a standard multimeter falls short. The NEO TOOLS Clamp Meter solves this by letting you simply clamp around a single conductor to read live current—safely and quickly. Whether you're troubleshooting industrial panels, checking motor draws, or servicing HVAC systems, this meter delivers reliable AC/DC current, voltage, resistance, capacitance, frequency, and temperature readings in one rugged tool.

Who is it for

Ideal for electricians, maintenance technicians, and DIY enthusiasts who work with electrical systems up to 400 A. Its CAT III 300V and CAT II 600V safety ratings make it suitable for residential and light commercial use, while the non-contact voltage (NCV) detector adds an extra layer of safety when checking for live wires.

Main features

• True RMS for accurate readings on non-linear loads
• Auto-ranging with 6000-count display for precision
• Non-contact voltage detection (NCV) with visual and audible alerts
• Measures AC/DC current up to 400 A, AC/DC voltage up to 600 V

Tips

Always ensure the test leads and thermocouple are properly rated for the measurement. For current measurements, clamp around only one conductor at a time to avoid incorrect readings. Keep the meter clean and store it with the protective cover when not in use to extend its life.
