Clamp multimeters & accessories that keep projects moving
When you need to measure live current on a motor, verify inrush on a power supply, or safely troubleshoot campus lab benches, a reliable clamp multimeter and the right accessories save hours. Communica stocks a broad range of clamp meters, flexible current probes, test leads and non-contact probes so South African makers, students and technicians can finish projects on schedule - with local availability, branch pickup and VAT-compliant invoices.
Why choose a clamp meter over conventional multimeters?
Clamp meters let you measure AC (and many models DC) current without breaking the circuit or stripping wire insulation. That reduces risk, speeds up diagnostics and is ideal for HVAC, robotics, power electronics labs and field service. Paired with the right accessories - true-RMS probes, flex clamps and insulated leads - they become a versatile diagnostic platform.
Key specification callouts to compare
When selecting, prioritise the specs that matter for your application: current range and resolution, true-RMS capability, frequency response for non-sinusoidal loads, jaw opening size, and safety rating expressed as a category. Below is a concise comparison to guide quick decisions.
| Spec | What it means | Why it matters |
|---|---|---|
| Current range | Maximum measurable Amps | Ensures you can read inrush currents or high-load motors |
| True-RMS | Accurate on distorted waveforms | Essential for VFDs, switching supplies and PWM-driven motors |
| Jaw diameter | Size of conductor that fits | Large cables and busbars need wide jaws or flexible probes |
| Frequency bandwidth | Hz range the clamp supports | Important for variable frequency drives and non-sinusoidal currents |
Common accessory bundles and typical uses
- Flexible Rogowski probes + high-range clamp: useful for measuring large conductors in solar or industrial environments.
- Insulated 1000V test leads + magnetic pickup probe: ideal for tertiary labs and field service where insulation and hands-free sensing reduce risk.
- Data-logging clamp + USB cable: for long-duration motor startup and energy monitoring in student projects.
