Voltage Tester Neon Screwdriver MEGA 250V 190mm model 10582

Neon screwdriver voltage tester MEGA 250V 190mm model 10582 is a handheld electrical tester designed to indicate the presence of AC voltage up to 250 V. The tool features a 190 mm insulated shaft and a built-in neon indicator that illuminates when it detects live conductors. Intended for quick checks of outlets, switches, wiring and circuit components, this tester provides a simple visual confirmation of voltage for electricians and competent DIY users.

Advantages

The neon indicator provides a direct visual signal when voltage is present, enabling fast identification of live conductors without complex setup. The compact, pen-style form with a 190 mm shaft allows access to recessed terminals and switches, while the insulated handle and shaft reduce the risk of accidental contact. The tester operates without batteries, offering immediate readiness for basic voltage checks and troubleshooting on AC installations up to 250 V.

Suitable for

• Quick presence checks on mains outlets and sockets
• Identifying live conductors in switches and junction boxes
• Basic troubleshooting of household and light commercial electrical circuits
• Verifying whether wiring is live before performing non-live work

Key specifications

• Maximum detectable AC voltage: 250 V
• Shaft length: 190 mm
• Indicator type: neon lamp
• Form factor: pen-style handheld tester
• Power source: non-battery (voltage-dependent neon indicator)

How to use

Hold the insulated handle and place the tip of the shaft onto the conductor or terminal to be tested. Make contact with the exposed metal or contact point while keeping your body away from exposed live parts. When the tip contacts a live AC conductor within the specified voltage range, the neon indicator will light. For proper operation, ensure the tester tip makes firm contact with the conductor and that the reference contact (often a finger on the metal cap or a grounding point) is maintained if required by the design. Do not use to measure exact voltage values—this tester only detects presence of AC voltage.

Usage recommendations

Use this tester only for presence checks on AC installations up to the specified voltage. Always follow applicable safety procedures: isolate circuits when performing live work, wear appropriate personal protective equipment, and verify results with a suitable multimeter or voltage tester for definitive measurements. Avoid using the tester on damaged insulation or in wet conditions.
