This category has the Marmonix True RMS clamp meters: the MCA-212 (1200 A AC/DC), the MCA-206 (600 A AC/DC) and the MCA-204 (600 A AC). Each one measures current through its jaw without breaking the circuit and works as a full multimeter for voltage, resistance, capacitance, frequency and Type-K temperature. Buying from Marmonix means you get the meter direct from the brand, with official datasheets and manuals, a 2-year warranty, and local supply and support across the UAE and GCC.

How to choose a clamp meter
1. Current type: AC only for most building loads, or AC/DC for solar PV, batteries, UPS, EV chargers and DC drives.
2. Current range: 600 A covers most sub-mains, motors and HVAC; choose 1200 A for large feeders and main LV panels.
3. True RMS: essential on VFDs, LED lighting and IT loads. All Marmonix clamp meters have it.
4. Safety category: CAT III 600 V for distribution boards; CAT IV 600 V at the origin of the installation.
5. Extra functions: inrush for motor and compressor starts, NCV for live-wire checks, µA for flame sensors and control circuits, and Type-K temperature for HVAC.
Who uses clamp meters
Electricians and MEP contractors (load balancing, breaker trips), HVAC technicians (compressor current and inrush, capacitors, temperature), facility and plant maintenance teams (motors, pumps, VFDs), and solar PV installers (DC string and battery current).

Clamp meter FAQ
What is the difference between an AC and an AC/DC clamp meter?
An AC-only clamp such as the MCA-204 uses a current transformer jaw and cannot read DC. AC/DC models such as the MCA-206 and MCA-212 use a Hall-effect sensor, so they also measure DC current on solar PV strings, battery banks, UPS, EV chargers and vehicle systems.
Why do I need a True RMS clamp meter?
VFDs, LED drivers, UPS and IT loads draw distorted current. An averaging meter can misread it by a wide margin, while a True RMS meter reads the real heating value. All three Marmonix clamp meters are True RMS.
Which clamp meter is right for a distribution board?
Use a meter rated for the location. The MCA-206 and MCA-204 are rated CAT III 600 V for building distribution boards and fixed installations. The MCA-212 is rated CAT IV 600 V for service entrances, main LV panels and outdoor supply.
How do I measure motor starting current?
Use inrush mode on the MCA-204 (it captures start-up current in a 100 ms window) or the MCA-206, or peak hold on the MCA-212. Clamp one conductor only, never the whole cable.
Do you supply clamp meters across the GCC?
Yes. Marmonix supplies clamp meters across the UAE, Saudi Arabia, Oman and the wider GCC, with a 2-year warranty, official datasheets and local support.
