Your Local Supplier of Ammeter Testers
An ammeter tester is essential for anyone working with electrical circuits, whether you're a student, technician, or engineer. These instruments measure electric current (in amperes) and help diagnose faults or verify system behaviour in everything from lab projects to industrial maintenance.
Communica stocks a wide variety of ammeter testers for sale in South Africa, including portable digital multimeters, clamp meters, and modular panel ammeters for integration into equipment. Our catalogue features brands trusted in education and industry, such as UNI-T, Mastech, Extech, and Fluke, as well as accessible options for makers and schools.
Types of Ammeter Testers Available
- Handheld digital multimeters - for general diagnostics, combining current, voltage, and resistance measurements.
- Clamp meters - non-contact measurement of AC and DC current, ideal for industrial applications and wiring checks.
- Panel mount ammeters - for permanent current monitoring within control panels, power supplies, and machines.
- Analogue ammeters - used in retrofits, vehicles, or educational experiments.
Tip: When choosing an ammeter for sale, check the maximum current range, probe types, input protections (fuses/overload), and display format (digital vs. analogue).
Specification Table - Comparing Common Ammeter Tester Types
| Type | Typical Range | Resolution | Best For |
|---|---|---|---|
| Digital Multimeter | 200 uA to 10 A | 0.1 uA to 1 mA | General electronics, field use |
| Clamp Meter | 1 A to 600 A | 0.01 A to 0.1 A | Electrical installation, industrial panels |
| Panel Ammeter | 0-5 A or 0-50 A (CT) | Varies by model | Continuous monitoring, equipment |
| Analogue Meter | uA to 20 A | Gauge markings | Education, vehicles, legacy gear |
Selecting the Right Ammeter Tester for Your Need
Selection depends on application, accuracy required, and safety. Here are some practical points:
- Students/DIY: Affordable digital multimeters are versatile for breadboards and electronics labs.
- Technicians/Electricians: Clamp meters allow fast, non-invasive current checks on live wiring.
- Panels/Machines: DIN-rail or panel mount ammeters provide real-time monitoring.

Installation, Application, and Local Buying Tips
Example: Wiring a Digital Ammeter Into a Circuit
Power Source (+) ----[Ammeter + Terminal]----[Load]----[Ammeter - Terminal]---- Power Source (-)
Always observe correct polarity and maximum allowable current. Use proper fusing and disconnect power before wiring. Clamp meters simply close around the conductor-no circuit break needed.
Formulas and Current Measurement Examples
| Example | Formula | Application |
|---|---|---|
| Ohm's Law | I = V / R | Estimate current before measuring |
| Current Draw | I = P / V | Appliance draw at 230 V (SA mains) |
South African Note: Most portable ammeter testers are rated for 230 V mains and include replaceable or ceramic fuses. Always check for CAT-II/III/IV input protection if using on electrical panels or in field work.

Common Troubleshooting Tips
- Meter won't display current: Check if on correct range; inspect for blown internal fuse or loose probe connection.
- Clamp meter reads zero on live wire: Ensure only one conductor is inside clamp jaw at a time.
- Panel meter displays erratic values: Verify correct shunt wiring and isolation in noisy environments.
