The Bestsellers Of The Phase Testers
In a list of bestsellers we have compiled the most popular phase testers for you.
Phase Tester Checklist
- The simplest version is the so-called lie pin, which looks very similar to a normal screwdriver. Unfortunately, it is not always 100% reliable. Even if the control light does not light up, this does not guarantee that the phase is really voltage-free. For complicated work, the lie pen is not necessarily suitable. For connecting a lamp , however, it is usually quite sufficient.
- Much more reliable are two-pole voltage testers. Some models are also suitable for checking RCD circuits.
- The third variant is a contactless voltage tester, but it is only suitable for alternating current . With it, you only need to approach the power source. The probe detects whether the test area is voltage-free or voltage-carrying.
- By the way: Single-pole voltage testers must be tested according to DIN VDE 0680-6 and double-pole voltage testers according to DIN VDE 0682-401.
- The range can be between a voltage of 0.3 – 1,200 V. Simple voltage testers are only suitable for a measuring range of approx. 150 – 250 V . With a two-pole voltage tester, you can also check your car battery effortlessly. Even standard models cover a measuring range of approx. 6 – 700 V . Better devices reach over 1000 V and can determine safe values even with heavy current and FI – circuits. Digital technology shows the exact values on a display or on a scale.
- Maximum values should be indicated on the product itself and must be considered urgently.
- Devices that have a modern LCD can provide you with similar functions as a Multimeter offer. Other devices only have a simple LED display.
- Contactless voltage testers give optical or acoustic signals, depending on the model. Screwdrivers with integrated voltage testers only have a thin filament.
- Voltage testers weigh between just 10 g up to 500 g. However, you should pay less attention to the weight than to the functions offered. A simple lie tester may be light as a feather, but it limits your options considerably.
- A two-pole phase tester is unfortunately somewhat heavier. Therefore, it should have a compact and handy shape.

FAQ About Phase Testers
A phase tester measures the voltage at the device you are measuring. If it lights up, there is voltage on the line.
To measure voltages, you need to hold the tip of the phase tester to the contact you want to measure. You yourself hold the phase tester at the rear end by the metal knob.
A phase tester is a type of screwdriver whose tip can be used to measure voltages.
A phase tester lights up as soon as there is voltage on a line.
