Voltage tester Proline 250V model 10542 — electrical probe for live voltage detection

Proline voltage tester model 10542 is a handheld electrical probe for detecting live voltage up to 250 V. Designed for quick verification of presence or absence of mains voltage, this compact tester works for wiring, outlets and electrical equipment. The device supports both contact and induction testing and does not require batteries, making it a convenient tool for electricians and DIY users performing basic troubleshooting and safety checks.

Advantages

The tester provides a clear step indication for contact tests at common voltage levels and supports detection across a metering range of 12–250 V at 50–60 Hz. Induction test capability allows detection of live conductors through insulation without direct contact. Battery-free operation reduces maintenance and the small form factor ensures easy portability and use in confined spaces.

Suitable for

• Quick verification of mains voltage in sockets and switches
• Checking presence or absence of voltage on wiring and junction boxes
• Detecting live conductors through insulation (non-contact testing)
• Basic electrical troubleshooting and safety checks for professionals and DIY users

Key specifications

• Metering range: 12–250 V, 50–60 Hz
• Contact test indications at 12, 36, 55, 110 and 220 V
• Induction (non-contact) voltage detection through insulation
• Handheld probe form factor, compact and portable
• Battery-free operation

How to use

For contact testing, place the probe tip on the conductor or contact point and observe the device's indication for the corresponding voltage step. For induction (non-contact) testing, bring the probe close to the insulated conductor or cable; the tester will indicate the presence of voltage without requiring direct metal contact. Use the tool with standard safety precautions—ensure appropriate personal protective equipment and isolate circuits when required by working procedures.

Usage recommendations

Use the Proline 10542 as a preliminary testing device to verify presence or absence of voltage. Do not rely on it as the sole safety verification for live work; follow applicable electrical safety standards, use additional suitable test equipment when necessary, and check functionality before each use.
