Find the Right Amperemeter or Power Meter in Johannesburg

Whether you're wiring up a student project, troubleshooting a circuit, or managing equipment in a commercial facility, accurate measurement tools are essential. Communica offers a complete selection of amperemeters (ammeters), voltage meters (voltmeters), and multi-function power meters, available for immediate sale in Johannesburg. Choose from compact panel meters for integration, handheld devices for technicians, or lab-grade bench instruments-sourced from leading brands and with full local support.

Types of Electrical Meters Available

• Dedicated ammeters (current meters): digital, analog, clamp types
• Voltmeters: panel-mount or handheld, with AC/DC options
• Combo meters: combined voltage, current, and power display
• Power meters: energy, watt-hour, and multi-parameter for mains or low-voltage

Key Specifications to Compare

Popular Brands and Local Availability

• Mastech: value digital meters, multimeters, and panel instruments
• Extech: portable meters for labs, diagnostics, and education
• Generic panel meters: for integration in control panels, display boxes, and hobby builds

Choosing the Correct Meter for Your Needs

1. Decide if you need ongoing panel monitoring or portable spot testing.
2. Select your current and voltage measurement range (ex: 0-10 A DC or 0-600 V AC).
3. Check supply voltage compatibility and input type (direct or current transformer-fed).
4. Review physical dimensions for panel or DIN-rail mounting.
5. Look for extras: peak hold, averaging, true RMS, and backlight for low-light use.

Installation Notes & Application Examples

Wiring requirements vary by meter type and application. Many panel ammeters require installation in-line with the load. For higher currents, a dedicated shunt (separate or supplied) is used:

      ----(+) Supply
         |
         |
    [Ammeter]---[Load]
         |
        ---
       GND
Typical In-Series Amperemeter Connection

For handheld multimeters or clamp meters, simply select the ammeter mode and follow manufacturer safety instructions. Never exceed the device's rated input current or voltage limitations.

Sample Calculation

Example: If your project requires measuring the current draw of a 12 V DC circuit where the expected load is 1.5 A (peak 2 A), choose an ammeter with a 3-5 A range for margin. If using a shunt type:
Current (A) = Measured voltage across shunt (V) / Shunt resistance (Ohm).
