Electrical safety tester Topex 39D054 — handheld instrument, depth 190 mm, weight 26 g, 1 pc

The Topex 39D054 electrical safety tester is a compact handheld instrument designed for quick verification of mains voltage and basic electrical safety parameters. With a depth of 190 mm and weighing approximately 26 g, it is supplied as a single unit and intended for portable, on-site checks of electrical equipment and installations. The tester detects voltage in the 100–250 V range and features an insulated body and a profiled grip for secure handling. Conformance to relevant European safety standards is indicated by CE certification.

Advantages

The device combines low weight with a slim profile to facilitate easy carrying and single-handed operation during routine inspections. Its detection range of 100–250 V covers common mains voltages, while the insulated housing and profiled grip improve user safety and handling precision. The simple, single-unit design reduces setup time for fast checks and repetitive tasks.

Suitable for

• Quick on-site voltage checks of sockets, switches and power cords
• Routine electrical safety inspections in homes and small commercial premises
• Portable verification of mains presence before maintenance
• Use by electricians and maintenance personnel for basic troubleshooting

Key specifications

• Detection voltage range: 100–250 V
• Device depth (length): 190 mm
• Weight: approximately 26 g
• Insulated housing for user protection
• Profiled grip for improved handling
• Single-piece handheld form factor for portability

How to use

Before use, visually inspect the tester for damage and ensure it is clean and dry. Hold the instrument by the profiled grip and place the sensing tip near or into the contact point to detect presence of mains voltage within the specified 100–250 V range. Observe any built-in indicators or follow the device’s operating guidance to interpret detected voltage. Use single-handed operation to stabilize the tester while maintaining appropriate distance from live conductors as required by safe working practices.

Usage recommendations

Use the tester only on circuits within its 100–250 V detection range. Do not attempt to measure voltages outside this range or use the instrument as a substitute for detailed diagnostic equipment. Store the tester in a dry location and replace it if the insulation or grip shows signs of wear or damage. Follow local safety regulations when performing live checks and wear appropriate personal protective equipment where required.
