Clamp measuring instrument

Clamp measuring instruments, also known as clamp meters, current clamps, or amp clamps, are essential diagnostic tools for electrical engineers and technicians. These instruments allow non-invasive current measurement by clamping around a conductor without breaking the circuit. They typically measure AC and DC current up to several thousand amperes, with features like True RMS for accurate readings on non-sinusoidal waveforms, auto-ranging, and data hold. Advanced models include voltage, resistance, capacitance, frequency, and temperature measurement capabilities, often with CAT III or CAT IV safety ratings for industrial environments.

Clamp meters are widely used in industrial automation, electrical maintenance, HVAC systems, and power distribution panels. They are critical for troubleshooting motor circuits, checking load currents in three-phase systems (3P, 4P), verifying power quality, and performing safety inspections in switchgear and control cabinets. They are also employed in renewable energy installations, such as solar inverters and wind turbine generators, for monitoring current flow and detecting faults.

Our catalog includes digital clamp meters, AC/DC clamp meters, flexible current probes (Rogowski coils), and high-voltage clamp adapters. Key article codes like CM-1000 (1000A AC/DC True RMS), CM-600 (600A AC only), and FCP-3000 (3000A flexible probe) are available. The code structure typically follows: CM-XXXX for standard meters, where XXXX indicates maximum current rating, and FCP-XXXX for flexible probes. We also stock accessories like test leads, temperature probes, and carrying cases.
