Voltcraft VC-321 digitálny kliešťový multimeter True RMS AC/DC 600V CAT II 300V CAT III 100A

The Voltcraft VC-321 stands apart from typical clamp meters by delivering true RMS accuracy in a compact, everyday tool. It reads AC current up to 100 A through a 17 mm jaw, and also measures AC/DC voltage to 600 V, resistance, capacitance, frequency, and temperature. With CAT II 600 V and CAT III 300 V safety ratings, it is suitable for both home and light industrial electrical work.

Highlights

• True RMS measurement for accurate readings on non-sinusoidal waveforms
• AC current up to 100 A without breaking the circuit
• AC/DC voltage up to 600 V, resistance up to 20 MΩ, capacitance up to 200 µF
• Frequency measurement 10 Hz – 10 kHz and temperature from -20 °C to +500 °C with K-type probe
• Non-contact voltage detection, continuity buzzer, and diode test
• Auto-ranging with 2000-count backlit display and data hold
• Powered by 2x AAA batteries, lightweight and portable

In daily use

The VC-321 is built for fast, confident diagnostics. Clamp around a single conductor to read current immediately; the slim jaw fits into tight panels. The backlit display remains readable in dim distribution boards, and the built-in NCV sensor helps identify live wires before you touch them. For HVAC or appliance repair, the K-type temperature input adds another layer of troubleshooting capability.
