Why order calibration equipment online from a local supplier
When you need calibration equipment - from multimeters and calibrators to reference sources and temperature baths - speed and accuracy matter. Communica keeps a broad range of test-and-measurement tools in South Africa so your project, classroom lab or service bench gets working sooner. Order online for branch collection or fast delivery, access VAT invoicing and account quotes, and tap local product knowledge that avoids long import lead times.
Reliable local stock and practical benefits
Local stock reduces downtime: collect from Samrand or our Pretoria and Cape Town branches, request a quote for departmental procurement, or choose delivery to site. For students and educators we support education purchases and can advise on durable, low-maintenance gear suited to repeated handling. For procurement teams, we provide VAT invoices and product specification support.
What to check before you order
- Measurement range and resolution: does the device read the smallest step you need?
- Accuracy and uncertainty: check the stated accuracy at the operating range used in your workflow.
- Calibration traceability: confirm the device can be calibrated to the laboratory standards you require.
- Accessories and leads: probes, adapters, and mains references often change the effective use of a calibrator.

Quick spec comparison table
Use this quick table to prioritise features when comparing bench calibrators, handheld calibrators and reference standards.
| Feature | Handheld Calibrator | Bench/Reference Calibrator |
|---|---|---|
| Typical use | Field checks and site verification | Lab-level calibration and documentation |
| Accuracy | 0.01% - 0.1% | 0.001% - 0.01% |
| Power | Battery-operated | Mains-powered, stable references |
| Portability | High | Low |
Small practical calculation - reading uncertainty
When you compare devices, convert percentage accuracy to absolute uncertainty over the range. Formula: uncertainty = (accuracy% / 100) × reading. Example: a 10.000 V reading with 0.02% accuracy gives 0.0002 × 10.000 V = 0.002 V uncertainty.
