• Voltage range & accuracy — Should clearly display voltage and display phase/neutral lines reliably.

  • Multi‑function capability — Can find breaks in insulated wires, check flow/current, detect phase line from insulation (non‑contact). For example, a digital tester can locate a wire break by reading where the display flash stops.

  • Safety insulation & build quality — Proper insulation of blade/tip (if direct contact type) so the user is protected.

  • Display clarity — Digital display preferred over neon indicator for quick, clear reading, especially in low light.

  • Durability & brand reliability — A tool you’ll carry around, so good build and known brand help.

  • Local availability & support in Pakistan — Shipping, warranty, accessories locally (or easy import).
