This 24-250V AC/DC voltage detector tester is an essential electrical inspection tool for electricians, construction workers, farmers and every family across Africa.
Unlike ordinary single-light voltage testers hard to recognize wires, our tester adopts dual red-green LED light beads with high brightness. The light stays visible even under strong sunshine outdoors. When touching live wire, both red and green lights turn on; only green light lights up when testing neutral wire, you can judge wire types at one glance without confusing circuits.
It supports wide voltage testing from 24V DC to 250V AC, fully fit for local household power sockets, generator wiring, farm agricultural equipment circuits and building construction power lines, covering all daily electrical testing scenarios.
Equipped with practical self-check function to guarantee safe use. Before testing any circuit, just hold the metal probe with one hand and touch the top copper cap with another hand. Illuminated lights mean the tester is in normal working condition; no light reminds you to replace the built-in battery to avoid test failure.
The whole body is made of transparent insulated anti-break plastic, which can effectively isolate electric leakage and prevent electric shock hazards. The internal precise circuit board is stable and not easy to damage under frequent bump on construction sites. A portable clip is designed on the side, you can hang it on work clothes or tool bags for easy carrying during outdoor renovation and farm work.
Widely used for home socket safety check, wall wire arrangement, distribution box fault detection, farm motor circuit inspection, workshop electrical maintenance and DIY circuit testing. Lightweight, safe, intuitive and affordable, this dual-color voltage tester is a must-have safety tool for every African household and professional electric worker.
