Clamp multimeters in stock: reliable current measurement when you need it
Get the right clamp multimeter and accessories without long waits. Whether you're a university lab prepping practicals, a field technician diagnosing motors, or a maker building a battery management rig, we keep a practical selection of AC/DC clamp meters, flexible current probes, test leads and spare jaws ready at our Samrand warehouse and branches. Short lead times and branch collection mean you can move from diagnosis to repair in one day.
Why choose a clamp multimeter for hands-on work
Clamp meters measure current safely without breaking the circuit, reducing risk for quick troubleshooting on live wiring. Look for model-specific features such as true RMS for non-sinusoidal loads, inrush current capture for motor start diagnostics, and flexible Rogowski probes for tight cable bundles. We stock options that balance accuracy, durability and value for South African education and trade use.

Compare common features at a glance when selecting a meter for a task.
| Feature | Entry-level | Prosumer | Professional |
|---|---|---|---|
| Current range | 0-400 A | 0-1000 A | 0-3000 A (with Rogowski) |
| True RMS | No | Yes | Yes, high accuracy |
| Inrush capture | No | Optional | Yes |
| Accessories | Basic leads | Backlit, probes, case | Rogowski, extra jaws, calibration kit |
Selection criteria and practical tips
- Choose true RMS meters for variable-speed drives or non-linear loads common in workshops and labs.
- If you measure large conductors or harnesses, use flexible Rogowski probes for access and safety.
- Match accessory ratings (voltage and CAT safety rating) to the system under test - higher CAT ratings for three-phase mains work.
- For teaching labs, consider rugged models with simple menus and removable test leads for shared use.
Simple current-to-power check (practical formula)
Use these quick calculations on-site. For single-phase systems, estimate load power:
P = V × I × PF
Where P is watts, V is measured voltage, I is measured current, and PF is power factor (use 1 for resistive loads; for motors assume 0.7-0.9 if unknown). This helps size fuses, cabling and thermal protection during troubleshooting.
