Product information

Description

STANLEY STHT0-66121 — mains voltage tester 220–250V is a compact handheld circuit tester designed to verify the presence of AC line voltage in the 220–250 V range. The tester is intended for quick checks of sockets, switches and exposed wiring to identify live conductors and confirm whether a circuit is energised before starting electrical work. Its slim, screwdriver-like form makes it convenient for use in tight spaces and for carrying in a toolbox.

Advantages

The STANLEY mains voltage tester provides a fast visual indication of live voltage within the 220–250 V range and is simple to operate without complex setup. Its compact, single-screwdriver style design allows access to confined areas and basic probe contact with terminal points. The tool is suitable for repeated brief checks and is lightweight for handheld use, offering a practical option for electricians and DIY users performing routine safety verifications.

Suitable for

Verifying presence of mains voltage in household and commercial sockets (220–250 V)
Checking switches, plugs and visible wiring before maintenance
Quick fault finding and basic electrical safety checks
Use by electricians, tradespeople and DIY home users

Key specifications

Nominal detection range: 220–250 V AC
Form factor: compact, screwdriver-style handheld tester
Probe/tip type: flat blade style tip suitable for contact with screw terminals and flat contacts
Operation: direct-contact live voltage detection with visual indication
Typical applications: sockets, switches, exposed wiring and terminal checks

How to use

Ensure that you follow safe working practices and isolate circuits where appropriate. To check for mains voltage, place the tester's tip in contact with the conductor or terminal to be tested while maintaining a firm grip on the insulated handle. Observe the tester’s visual indication to determine whether the conductor is live within the 220–250 V range. Avoid applying excessive force and do not use the tester on unknown voltages outside its specified range. If the presence of voltage is confirmed, do not proceed with work until the circuit is safely isolated and locked out according to local regulations.

Usage recommendations

Use the tester only for brief verification checks on intended 220–250 V AC circuits. Regularly inspect the tester tip and handle for damage before use. For more detailed diagnostics or work on energized systems, use appropriate insulated tools and measurement equipment or consult a qualified electrician.
