Voltage testers

Buy professional voltage tester

A phase tester, also called a voltage tester, is used to detect voltage on an electrical device or line. These devices are available in different versions, depending on their intended use.

What is a professional voltage tester?

Since caution is always required when working with electrical devices or wiring (keyword: electric shocks), maximum safety should be prioritized. In situations where…
For testing electrical components for voltage, a professional voltage tester is necessary. This device helps locate live wires, breaks in cables, defective bulbs in Christmas lights, etc.

Electricians should carry a voltage tester with them at all times, as they can use the tool daily at work.

Frequently Asked Questions

  • What is the difference between a voltage tester, a socket tester, and a fuse finder?

    A voltage tester detects voltage and, depending on the model, continuity, phase sequence, or residual current device (RCD) function; a socket tester checks the wiring of a socket; a fuse finder identifies the corresponding circuit breaker for each socket. For verification of disconnection, the two-pole voltage tester is the relevant device. The PAN Socket-Test-2 is suitable for quick socket checks, and the PAN Circuit Finder is used for circuit identification.

  • When is a fuse finder or circuit finder useful?

    A fuse finder is useful when you need to quickly identify the fuse, circuit breaker, or residual current device (RCD) associated with a wall socket. The PAN circuit finder works with a transmitter and receiver: The transmitter is plugged into the wall socket and sends a signal into the wiring, while the receiver locates the corresponding circuit breaker in the distribution board. This reduces search time during installations, maintenance, and troubleshooting in residential, commercial, and industrial buildings.

  • What does a socket tester or outlet tester check?

    A socket tester quickly and reliably checks the wiring of grounded sockets using visual indicators. The PAN Socket-Test-2 detects typical wiring errors such as missing conductors or reversed connections, displays the status via green and red LEDs, and features an LCD voltage display as well as a 30 mA residual current device (RCD) test. The device is designed for Schuko sockets, requires no battery, and is suitable for installation, maintenance, and servicing.

  • Can PANCONTROL voltage testers also measure DC voltage, for example in PV systems?

    Yes, selected PANCONTROL voltage testers also measure DC voltage. The PAN SolarCheck 1500V is specifically designed for photovoltaic applications and tests DC voltages up to 1500 V DC and AC voltages up to 1000 V AC. Depending on the model, the PAN Volttester 400, PAN MV-1000A, and PAN MV-1000AD also detect AC and DC voltages. Non-contact voltage testers, on the other hand, only work with AC voltage fields.

  • Which measurement category do voltage testers require for work in switchgear and on the power grid?

    For measurements within fixed building installations, at least CAT III is required; for measurements at the service entrance, on meter installations, or in areas close to the grid, CAT IV is required. Voltage and continuity testers such as the PAN MV-1000A, PAN MV-1000AD, PAN SolarCheck 1500V, or PAN Allrounder 200AD meet CAT III 1000 V / CAT IV 600 V standards and thus cover typical professional applications in electrical installation, maintenance, and industry.

  • How does a non-contact voltage tester work and what are its limitations?

    A non-contact voltage tester detects alternating electric fields on live conductors without direct contact. Devices like the PAN Voltfinder are suitable for quick preliminary checks, locating live wires, and inspecting junction boxes, cables, or devices. However, non-contact voltage testers do not replace a two-pole voltage tester for standard-compliant disconnection verifications. Furthermore, they are not suitable for DC voltages.

  • What distinguishes the PAN Volttester 400 from the PAN MV-1000A, PAN MV-1000AD, PAN SolarCheck 1500V or PAN Allrounder 200AD?

    The PAN Volttester 400 is a simple 2-pole voltage tester for quick AC/DC voltage testing up to 400 V in low-voltage installations. The PAN MV-1000A and PAN MV-1000AD are advanced voltage and continuity testers up to 1000 V AC/DC and are suitable for switchgear, three-phase systems, and maintenance work. They offer additional features such as phase rotation indicator, audible continuity test, single-pole phase test, and 30 mA residual current device (RCD) test.

    For photovoltaic applications, the PAN SolarCheck 1500V is the specialized solution: It is designed for DC voltage testing up to 1500 V and AC voltage testing up to 1000 V, making it suitable for PV strings and solar power systems. The PAN Allrounder 200AD combines voltage testing, multimeter functions, and a current clamp in a single device. It is suitable for PV and electrical applications with measuring ranges up to 1500 V DC, 1000 V AC, and 200 A AC/DC.

    For simple voltage testing, the PAN Volttester 400 is sufficient. For standard-compliant testing in switchgear and three-phase environments, the PAN MV-1000A or PAN MV-1000AD are the more comprehensive choice. For PV systems, the PAN SolarCheck 1500V is preferable; for flexible service and maintenance operations with additional current measurement, the PAN Allrounder 200AD is a good option.

  • How can you identify a suitable 2-pole voltage tester for professional use?

    A professional 2-pole voltage tester must be suitable for the voltage range, measurement category, and application. CAT III devices are required for work in sub-distribution boards, switchgear, and fixed installations; CAT IV is relevant for main distribution boards and measuring points close to the mains. Features such as load activation, continuity testing, phase sequence indication, residual current device (RCD) testing, IP protection rating, and easily readable LED/LCD displays increase its practicality in electrical work and industrial maintenance.

  • Why are single-pole phase testers insufficient for professional electrical work?

    For standard-compliant work on electrical installations, a two-pole voltage tester is required. A single-pole phase tester does not provide reliable voltage readings, is dependent on the ground and earth reference, and is not suitable for documented disconnection verification. Single-pole phase testers such as the PAN PSD140TR, PAN PSD190, or PAN 2000 are therefore intended only for simple preliminary tests or special applications, not as a replacement for a two-pole voltage tester.
