Precision equipment, supplied for scale and speed
Communica supplies a broad selection of calibration instruments suitable for small calibration labs, university test facilities and contract service centres that need wholesale quantities and predictable lead times. We focus on availability, clear specifications and service-friendly accessories so your team can get devices into service fast - with VAT invoices, account quoting and branch collection available across our Samrand, Pretoria and Cape Town locations.
Why buy wholesale from a South African distributor
Buying locally reduces import delays and simplifies procurement paperwork. For bulk orders we provide tailored quotations, consolidated VAT invoicing and the option to collect from our head office in Samrand or a regional branch. If you need to inspect stock before purchase, check branch availability and hours on our Branches & Trading Hours page View branches and hours.
Product range and common use cases
Typical wholesale lines used by calibration houses include multimeter calibrators, precision voltage/current sources, temperature baths and reference thermometers, signal generators and high-accuracy LCR meters. We stock leading brands and maker-friendly test gear so you can build service benches for electrical, temperature and RF calibration tasks.

Specification callouts to check before ordering
When specifying calibration equipment in bulk, prioritize these measurable attributes rather than marketing names:
- Accuracy and uncertainty (ppm or %), across the measurement range
- Traceable reference options and calibration ports for external standards
- Stability over time and required warm-up period
- Interfaces for automation: LAN, USB, GPIB or SCPI command set
- Power and environmental limits (temperature, humidity)
Below is a compact comparison table that helps buyers choose a starter kit for DC voltage and resistance calibration work.
| Model class | Key spec | Best for |
|---|---|---|
| Precision DC Source | 0.01% accuracy, 0-20 V | Multimeter calibration |
| 0.1 Ohm-1M Ohm Calibrator | 0.02% stability | Resistance standards |
| Temperature Reference | ±0.1 °C, liquid bath | Thermometer and RTD calibration |
