Electrical Tester tool

Measurement capabilities — The tool should test AC/DC voltage, continuity, sometimes phase/impedance depending on application.

Safety ratings & standards — Look for CAT III/CAT IV ratings (e.g., 600 V/1000 V) and compliance with IEC or EN standards for electrician use.

Display & indicators — LED or LCD displays, audible or visual alerts (for live voltage) and clear markings reduce error.

Probe & insulation quality — Insulated probes, durable cable assembly and safe construction (especially when working on live circuits) are critical.

Features & ergonomics — Additional useful features include non‑contact voltage detection, backlight, flashlight, auto‐power off, and ergonomically safe handles.

Suitability for local conditions — Consider the voltage ranges you’ll test (for Pakistan: e.g., 230V single‑phase, 400V 3‑phase), local support/spare parts, and tool durability in tough environments.
