Analogue Panel Meters for Sale in South Africa - Voltage, Current & Custom Dials | Communica

Analogue Panel Meters for Monitoring Voltage, Current & More

Analogue panel meters remain a trusted, visible solution for monitoring electrical parameters directly on control panels, equipment enclosures, and laboratory setups. These meters use moving-coil or moving-iron mechanisms to provide easy-to-read displays of voltage, current, frequency, or other electrical values in real time. They're widely used across South African factories, schools, test benches, and distribution boards due to reliability, simplicity, and their ability to operate without a power supply.

Communica offers a comprehensive selection of analogue meters for sale - covering popular ammeter and voltmeter types from leading brands. Orders can be collected at branches in Samrand, Pretoria, and Cape Town, or shipped nationwide to enable fast replacements or new panel builds.

Types & Standards of Analogue Panel Meters

Analogue meters come in a range of movement types, case sizes, and measurement functions. The following table gives a side-by-side comparison of key technical considerations:

Popular Brands & Product Ranges at Communica

• Sanwa
• Yokogawa
• CEM
• Chint
• Generic or blank-face meters for custom scaling

Communica often stocks both branded and cost-effective generic options for both standard meter ranges and blank dials (ready for custom scales), supporting education, prototyping, or special process panels. Browse the Test & Measurement category or filter by brand to compare specs.

Selecting the Right Analogue Meter

Choosing the best analogue panel meter depends on your measurement type, range, panel cutout, and environmental conditions. Follow these steps for consistent results:

1. Confirm the parameter: Voltage, current, or frequency. For current above 5A, specify compatible shunt values (e.g., 50mV/60A).
2. Check scale and graduation: Choose dials with sufficient granularity for your application - more marks help in lab settings.
3. Fit the cutout size: Standard case sizes are 48x48, 72x72, 96x96 mm, matching DIN and local industrial enclosures.
4. Check AC or DC compatibility: Some meters operate on both, others only on DC (moving coil) or AC (moving iron).
5. Consider durability: For high-vibration or field use, pick meters with secure mounting and robust bezels.

Example Calculation: Adding a Shunt for High-Current Ammeters

For current measurement above typical meter limits (often 5A), use an external shunt resistor:

Shunt resistors and dial overlays for current scaling are also available for South African panel builders and education labs at Communica.

Local Buying Considerations

• Check branch stock for same-day pickup if urgent, or request lead times for bulk/rare models.
• VAT invoices are available for procurement teams and tertiary institutions. Request a formal quote for orders or sponsored lab setups.
• Communica supports both online and branch sales - confirm availability, especially for common laboratory/educational models in South Africa.
