VOLTCRAFT VC-321 ISO Calibrated Digital Clamp Meter CAT II 600V CAT III 300V 2000 Counts VC-15815575

The VOLTCRAFT VC-321 stands apart from ordinary clamp meters by combining ISO calibration with a compact, rugged design that handles daily electrical diagnostics without compromise. It measures AC current up to 600 A through a 30 mm jaw, plus AC/DC voltage, resistance, capacitance, frequency, and temperature—all with average sensing and a clear 2000-count backlit LCD. Safety is assured with CAT II 600 V and CAT III 300 V ratings, making it suitable for both residential and light industrial environments.

Highlights

• ISO calibrated for verified measurement accuracy
• AC current up to 600 A with 30 mm jaw opening
• Measures AC/DC voltage, resistance, capacitance, frequency, and temperature
• CAT II 600 V and CAT III 300 V safety ratings
• 2000-count backlit LCD for easy reading in low light
• Data hold, auto-ranging, diode and continuity test functions

In daily use

Electricians and technicians will appreciate the VC-321's auto-ranging capability and data hold function, which freezes readings for later review. The backlit display ensures visibility in dim distribution boards or tight spaces. With its average sensing technology, the meter delivers stable readings on sinusoidal waveforms, typical for most mains-powered equipment. The included temperature measurement extends its utility to HVAC and motor maintenance tasks.
