  • Built-in LED flashlight adds illumination for work in dark spaces

Voltage tester kit for electricians

The KEHIPI PST255-US combines a non-contact voltage pen with a US socket tester for professional and home wiring checks. The pen detects AC voltage from 12V to 1000V in high sensitivity mode and 48V to 1000V in low sensitivity mode across 50/60Hz circuits. Three voltage categories are shown through flashing red LEDs and audible alarms for clear identification.

Two-button operation and socket diagnostics

A simple two-button design lets users touch the tip to terminals, outlets or supply cords for instant voltage presence indication without contacting live parts. The socket tester plugs directly into 3-wire receptacles to verify correct wiring and trip GFCI devices, flagging five common fault conditions through LED patterns. An integrated LED flashlight adds illumination in dim enclosures.

Dual-mode detection and outlet verification

High and low sensitivity modes on the pen allow the user to distinguish between live conductors and induced voltages on de-energised cables. The socket tester provides a go/no-go indication for receptacle wiring and exercises GFCI protection in a single step. Together they reduce the number of separate instruments an electrician carries for basic safety verification.

Questions about this item

How long can the 12-1000V detector run continuously before its batteries need changing?

The voltage tester pen operates on standard batteries; continuous use duration depends on battery capacity and the frequency of LED and sound alerts during detection.

Does the pen or the socket tester become hot or noisy during all-day use on a job site?

Neither the non-contact voltage pen nor the GFCI socket tester generates noticeable heat or audible noise beyond the built-in alert buzzer when voltage is detected.

What batteries must I already have to start using the kit right away?

The voltage tester pen requires two AAA batteries, which are not included, while the socket tester draws power directly from the outlet under test.
