Clamp Meters & Clamp-On Ammeters
Marmonix clamp meters let you measure electrical current safely and instantly — without disconnecting wires or interrupting the circuit. Simply clamp the jaw around a conductor to read AC (and on selected models, DC) current, making clamp-on ammeters ideal for electricians, HVAC technicians, and industrial maintenance teams.
Our clamp meters combine current measurement with full multimeter functions: voltage, resistance, continuity, frequency, and temperature. True-RMS models deliver accurate readings on motors, drives, and other non-linear loads, while wide jaw openings handle thick cables and busbars.
With clear backlit displays, data-hold, and rugged, safety-rated housings, Marmonix clamp meters are built for daily use in demanding environments. Explore the range below to compare current ranges, jaw sizes, and features.
