Voltage testers also known as voltage indicators and electricity testers are essential pieces of test equipment for electricians that measure ac/dc voltage and continuity. They are small hand-held devices that give the user an instant and clear indication if a circuit is live and provides you peace of mind when it comes to ensuring your safety. Voltage testers are used by electrical engineers for electrical installation and servicing in domestic, commercial, and industrial applications and are essential devices for testing connections and breaks in cables. You can learn more about [how to use a voltage tester](/web/content/discovery/ideas-and-advice/voltage-testers-guide) in our guide.

Voltage testers and indicators include a wide range of display features such as LED lights and audible signals to alert the engineer when live voltage is present. Some voltage indicators can also feature LCD display screens, informing the user that the line is powered and must be shut off before working with electricity. Our range of voltage testers have been sourced from leading brands such as Beha-Amprobe, Chauvin Arnoux, Gossen Metrawatt, Martindale, John Drummond, Testo, Fluke and many more ensuring we have the ideal testing solution for your applications.

### Types of voltage testers

Voltage testers are available in many different styles and sizes suited for different needs. The small electrical pen testers can be carried in a pocket or tool bag with ease. Types include:

- Voltage detector pen or Volt stick
- Non-contact Voltage Testers
- Two pole voltage testers

### Why would you use a voltage tester?

By using a voltage tester to establish if voltage is present means that you are complying with health and safety recommendations for safe electrical work. They are now available everywhere for people that work with electricity to be able to test the voltage levels of their circuits without risking being electrocuted themselves. They can used to:

- Finding breaks in power cables
- Checking plug wiring and fuses
- Distinguishing between live and neutral wires
- Determining live cables injunction boxes
- Finding faulty switches

<p>Fluke's Voltage Testers are easy to use and provide accurate readings of voltage, current and resistance. Fluke's non-contact testers offer quick, accurate testing in tight spaces where there is little room for error or incorrect readings.</p><p>Fluke's Two Pole Voltage Testers feature a pistol grip shape designed for maximum comfort and control over long periods of use. With several other models to choose from, one is sure to fit your needs! When working with electricity, the right tester can be the difference between a safe job and an unfortunate accident. Fluke's non-contact voltage detectors provide electricians the confidence to perform their work from a safe distance. Fluke's voltage testers can be used at home and in the workplace by electricians and engineers to quickly find electrical problems.</p><h2>How do you use a Fluke Voltage Tester?</h2><p>Using a voltage tester is relatively simple. First, make sure that the tester has new batteries and turn it on. To test for presence of voltage, touch both leads to the suspected live metal or wire you are testing. If there is voltage present, the display will indicate one of three readings: AC (alternating current), DC (direct current) or OL (overload).</p><p>When using an analogue type dial-in meter, which is slightly different than digital LED type testers, you can check if voltage is present by connecting probes across any two points in a circuit and adjusting your meter until its pointer rests at 12 o'clock.</p>
