⚡ At a Glance
- • Voltage Detection: Neon indicator and a bright red LED signal live presence clearly for household mains checks
- • Best for: Electricians, maintenance technicians and competent DIY enthusiasts performing quick safety checks
- • Not ideal for: Detailed insulation resistance testing or measurements above 250 volts
A neon-equipped mains tester screwdriver with a transparent, fully insulated handle. Designed for rapid checks such as continuity, fuses, cable tracking and socket testing.
Instant Live-Circuit Confirmation – Thanks to neon indicator and red LED
A neon lamp in the clear handle illuminates when the metal blade contacts a live conductor and an earthing contact is made via the metal stud on the top. The red LED gives a bright visual cue when the tester is functioning correctly.
Quick visual feedback lets users identify live circuits fast and reduce guesswork. Visible illumination helps avoid accidental contact during routine checks.
Handheld Fault Finding – With multi-function testing capability
The tester completes simple circuits between the blade and the earthing contact to reveal continuity, blown bulbs, fuse condition, shorts and cable tracking. Specific checks for mains sockets and microwave oven leakage are supported via the same contact method.
Carry out basic diagnostics without switching tools, speeding up troubleshooting. Useful for routine maintenance and pre-work safety checks.
Safer Handling and Portability – Thanks to fully insulated transparent handle and pocket clip
A fully insulated handle separates the user from exposed metal parts while the transparent material houses the indicator for easy sighting. A pocket clip keeps the tester to hand for on-site convenience.
Comfortable fingertip grip reduces slippage during probing and helps maintain safety. Compact design and clip make it easy to store on a belt or in a toolbox for regular use.
