BSIDE S4 Smart Voltage Tester

BSIDE S4 highlights

AC Voltage Detection

BSIDE S4 is a smart voltage tester, it features a 300V max range and distinguishes the neutral-live wire according to the voltage. It can be used in mechanical repair, electricians, home use, and car repair.

NCV Non-Contact Voltage Detection Induction

When detecting nearby AC voltage, the LED displays a red screen and alarm buzzer sound, so the no-contact electrical measurement is safer.

LED Flashlight

It is equipped with an LED flashlight with high brightness, so you can use it at night, not afraid of the dark.

Intelligent Zero Fire Line Judgment

You can select the live zero firewire distinction function, and insert the pen needle into the hole for identification. Without traditional contact identification, electricity measurement is safer.

Route Breakpoint Detection

In NCV non-contact voltage detection mode, the breakpoint position is eliminated along the road when a single strand is charged.
