Testers

The online electrical wholesaler Onninen offers professional measuring devices in many different versions. Among them, testers (indicators) occupy an important place: phase, voltage and others. Discover all products from the tester category - both those in our company warehouse and those available for individual order.

Phase testers

We offer easy-to-use, non-contact phase and phase sequence indicators in a three-phase network. Colored LEDs inform the user about the clockwise or counter-clockwise phase sequence. The tester allows for testing phases in shock-resistant sockets and distribution boxes. It also allows for locating cable breaks in insulated and live lines. The effectiveness of the signaling is enhanced by an audible signal, the frequency of which increases with the increase in applied voltage. Our range also includes advanced phase sequence and motor rotation direction testers with a declaration of inspection. These are innovative devices that will allow you to determine the correctness of the connections made in a three-phase installation, and additionally check the motor speed. We have solutions from brands that have been recognized by professionals in the electrical and construction industries for years, such as Beha-Amprobe, Benning, Fluke and Sonel.

Voltage testers

Our range includes single-pole and two-pole voltage testers from leading manufacturers such as Benning, Fluke and Sonel. A voltage indicator is a small, handy device that allows for quick, simple and safe measurement of voltage in electrical installations. It is a standard element of equipment for professionals in the electrical power industry. An appropriate indicator, e.g. an LED diode, informs the user about the presence or absence of voltage. When choosing a current and voltage meter, you should focus on the measurement range and additional functions such as built-in memory, phase sequence indicator or a flashlight that allows you to illuminate the measurement site. Basic devices only inform about the presence or absence of voltage. For more demanding users, we recommend innovative electrical testers for voltage measurement. They enable completely non-contact, safe, easy and fast measurement of current and voltage as well as measurement of resistance and frequency. They operate without measuring cables (using open measuring clamps). The voltage and current value appears on the built-in, clear display.

Other testers

We also offer many other meters used by professionals and DIY enthusiasts. Our range includes:

• automotive voltage testers that make it easier to check vehicle installations,
• testers measuring wiring continuity, wire length and distance to wire damage,
• multi-testers for testing microwave ovens and television receivers for radiation,
• battery testers,
• verification devices electrical testers, digital multimeters and current clamps.

Whether you are interested in measuring voltage, temperature, noise, light intensity or another parameter, you will find a meter perfectly suited to your tasks at the Onninen electrical wholesaler.
