Voltage Range: While buying a voltage tester for your toolkit or workshop, the most important thing to consider is the voltage range as it tells you about the voltage values that you can check. If you want something versatile, then a voltage range of 12 volt to 1000 volt AC is going to be better than 50 volt to 1000 volt AC is going to be much better in most cases. Safety Compliance: If you are using something like a voltage tester, then it is highly likely that you are working with a high voltage current. To ensure your safety as well as for the voltage tester, it is quite important to go with one that includes some sort of safety compliance. Apart from CAT III 1000V and CAT IV 600V, you can also find CAT IV 1000V rating with many voltage testers for proper safety during operation. Display: To show you the voltage readings detected by your voltage tester, all of them rely on inbuilt displays. Although, while some of them may come with LCD displays, others may offer an LED display for better visibility in all scenarios.
Even though all these factors can come in quite handy to pick a voltage tester for your needs, you will certainly need to know more for getting the right one. Hence, all of the best voltage testers stated down below also have their major features and specifications explained along with a comprehensive “Buying Guide” so that you can buy the best voltage testers by the time you have made it to the end of this list.
