Test Leads & Probes - Quality Test Equipment for South African Makers

Why the right test leads and probes matter

When diagnosing circuits, verifying sensor signals or setting up lab benches, the test leads and probes you use determine accuracy, safety and efficiency. Communica supplies a wide selection of leads, multimeter probes, oscilloscope probes and accessory kits that balance flexibility with robust construction - so you spend less time fighting bad connections and more time fixing problems. Local stock reduces lead times and lets you collect from branches quickly.

Practical benefits for South African users

• Fast branch pickup from Samrand, Pretoria CBD or Cape Town to keep projects moving.
• VAT invoices and account quoting available for students, labs and procurement teams.
• Accessory bundles and common spare parts stocked to reduce downtime.

Product types and where to use them

Choose probes and leads by application: flexible silicone-insulated leads for bench work, banana-to-banana leads for power tests, insulated grabbers for live wiring, and 10:1 or 100:1 oscilloscope probes for high-frequency signals. For an overview of related product ranges, explore our Shop by Category and the All Products index.

Quick spec callouts

When comparing leads and probes, check these key specs:

Compatibility guidance

Match connectors to your equipment: banana plugs for most bench multimeters and power supplies, BNC or SMA for scopes and RF probes. For mixed setups, look for convertible or adaptor-ready leads to avoid repeated purchases. For brand and accessory choices, see our Shop by Brand page.

Example wiring diagram (multimeter leads)

Use this simple ASCII wiring guide when measuring voltage on a DC rail:

Multimeter (V) ---[ Red lead ]---(+ ) Node
Multimeter (COM) --[ Black lead ]---(- ) Ground

For continuity or resistance tests, ensure the circuit is de-energised before connecting probes to avoid damage to the meter or false readings.

Choosing the right lead or probe - selection checklist

Follow this quick checklist to pick the correct test accessory for your task: expected voltage/current, measurement type (DC/AC, frequency), connector compatibility, insulation flex, and whether you need accessories like crocodile clips, shrouded banana adaptors or probe tips. For education environments, choose rugged, low-cost kits with clear lab-friendly instructions.

Accessory bundles and commonly paired items

• Multimeter probe + spare tips bundle for student labs.
• Oscilloscope probe 10:1 with calibration tool and ground spring for signal fidelity.
• High-current leads with shrouded banana plugs and insulated clamps for power benches.

Troubleshooting common probe issues

If you see noisy readings or intermittent contact: inspect connectors for corrosion, replace frayed silicone leads, and verify probe attenuation settings on scopes. Use reference resistor checks and compare with a known-good meter to isolate faults.
