## Product Selling Points (for use in detailed images)

✅ **Multifunctional Phase Sequence Tester**: Supports positive phase / reverse phase / missing phase detection; combines live circuit testing, fault location and circuit maintenance in one device – an essential tool for electricians on site.

✅ **Dual audio-visual alerts**: Synchronised LED and buzzer feedback provides an intuitive distinction between in-phase and out-of-phase conditions, enabling rapid assessment of three-phase circuit status.

✅ **Magnetic design**: Built-in magnet on the rear allows it to attach directly to the distribution box casing, freeing up both hands and facilitating single-person operation.

✅ **Automatic Power Saving**: Automatically switches off after 5 minutes of inactivity to extend battery life.

✅ **Wide Voltage Measurement Range**: Up to 1000V AC, CAT III safety rating, 5.4kV insulation strength, ensuring safer high-voltage operations.

✅ **Compact and lightweight**: Weighs only approximately 200g with a 0.6-metre lead, making it convenient to carry and use for wiring tests.

✅ **Applications**: Verification of motor, distribution board and three-phase equipment wiring; troubleshooting phase loss, open circuits and reversed phase sequence faults.
