How do I choose between a bench multimeter and a handheld multimeter?

Choose based on use case: bench multimeters offer higher accuracy, better resolution, data logging and stable power for lab work, while handheld units prioritise portability, ruggedness and battery operation for field tasks. Compare specifications such as accuracy (ppm or %), input impedance, range coverage, sample/update rate and safety (CAT) ratings on the datasheet before buying.

Are Communica test instruments supplied calibrated or with calibration options?

Calibration status varies by product and manufacturer — check the individual product page or datasheet for supplied calibration information. If you require local calibration or a traceable certificate, contact Communica sales for recommended local calibration services and lead-time information.

What probes and accessories do I need for measuring high-frequency signals with an oscilloscope?

Use probes with bandwidth ratings equal to or greater than the oscilloscope bandwidth (typically 3–5× the highest signal frequency), low capacitance and proper impedance (e.g., 1 M? for passive, 50 ? for high-speed). Also use properly compensated probes, short ground leads or grounding accessories, and coaxial cables or differential probes for high-speed or floating measurements to reduce noise and ringing.

What safety checks should I perform before measuring mains or high-voltage circuits?

Verify the instrument and probe voltage/CAT ratings on the product label or datasheet and use leads, probes and fuses rated for the expected voltages and fault conditions. Work with the circuit de-energised when possible, use appropriate PPE and isolation techniques, and ensure a competent person supervises measurements on hazardous systems.

How can I check stock, collect orders from a branch, and get a VAT invoice for institutional purchases?

Check stock and estimated lead times on the product page or contact Communica sales for bulk or education enquiries; branches include Samrand (head office), Pretoria CBD and Cape Town with additional sub-distributors. You can select branch collection at checkout or arrange collection with sales, and request a VAT invoice at purchase or on collection by providing the required business or institutional details.

Buy calibration equipment with confidence from Communica

When deadlines and measurement accuracy matter, waiting weeks for import orders costs projects and credibility. Communica keeps a practical range of calibration tools - multimeters, reference sources, temperature calibrators and test accessories - available for South African makers, students and procurement teams. Our value is local availability, rapid branch collection from Samrand or Pretoria and supplier breadth across trusted international brands.

Why local stock matters

Calibrating equipment often requires quick turnaround for verification, spare probes, or accessory swaps. Having stock locally reduces lead times and lets you collect the item same-day at our Samrand head office or one of our branches. For education and research labs, we issue VAT invoices and provide account quotes to simplify procurement and asset tracking.

What we stock and where to look

Browse our test & measurement categories and filter by brand to compare specifications, accessories and replacement parts. Popular categories include handheld multimeters, precision voltage/current sources, thermometry calibration kits and test probes. Explore our collections to find compatible accessories and spare leads: Shop by Category.

Specification callouts to prioritise

When choosing calibration equipment, focus on accuracy class, resolution, stability and traceable calibration options. For instance, a 6.5-digit bench multimeter offers finer resolution than a 4.5-digit handheld, while a temperature calibrator’s immersion depth and probe interchangeability determine its suitability for your applications.

Type	Key spec	When to choose
Bench multimeter	0.003% accuracy, 6.5 digits	Lab calibration and reference checks
Handheld calibrator	0.05% accuracy, rugged	Field verification and maintenance
Temperature calibrator	±0.1°C stability, dry-well or liquid	Temperature sensor and RTD checks

Compatibility and accessory bundles

Match connectors and leads to your device under test - BNC, banana, Kelvin clips or thermocouple heads. We commonly pair bench multimeters with 4-wire Kelvin leads and calibrated shunts for low-ohm measurements. Check the product pages and our brand index for recommended accessories: Shop by Brand. For immediate availability and local pickup options see calibration equipment in stock.

Selecting the right calibration tool - practical guidance

Quick selection checklist

Define the measurand and required tolerance (voltage, resistance, temperature).
Match accuracy class and resolution to the device under test.
Verify physical interfaces and probe compatibility.
Plan for traceable calibration certificates if required by audits.

Example: for validating a laboratory power supply with 0.1% output regulation, select a reference meter with better than 0.05% accuracy and low burden current shunt capability. For temperature sensors used in process control, prefer a dry-well calibrator with adjustable depth and repeatable stability.

Troubleshooting common procurement objections

Concern: "Will spare probes be available locally?" Answer: We stock common probe types and spare leads; check immediate availability with "Check Stock in Samrand" or branch collection options via our branches page: Branches & Trading Hours. Concern: "What about quotations and VAT invoices for institutional buying?" Answer: We offer account quotes and VAT invoices to simplify procurement and asset management - contact our sales team through the site for tailored quotes.

When calibration vs verification is enough

If your requirement is routine verification between formal calibrations, a handheld reference or portable calibrator may be the most cost-effective option. For accreditation or audit evidence, select instruments that are serviceable and can be issued with a traceable calibration certificate from the manufacturer or an accredited lab.

Final summary and next steps

Communica’s local stock, technical advice and branch collection make sourcing calibration equipment straightforward. Use our product index to compare models and accessories, then confirm local availability: All Products.
