Multifunction testers or MFTs are handheld versatile devices used to verify the safety of electrical installations in domestic, commercial, and industrial settings. These installation testers are designed to streamline and simplify electrical testing processes and ensure that fixed wiring is safe and correctly installed to meet relevant local standards and safety requirements
MFTs are ideal for testing a range of electrical parameters such as voltage, earth resistance, loop impedance and more. Many multifunction testers offer additional features such as Bluetooth, allowing you to store and transfer data from the device to a computer or mobile device. Here at RS, we have sourced multifunction test meters from leading brands such as Fluke, Megger, Gossen Metrawatt, RS PRO, and many more. You can learn more in our multifunction testers guide.
Multifunction Testers can be categorised with many different naming conventions, they are also commonly called Electrical Testers and Multifunction Installation Testers. However, even though they use slightly different names they all essentially do very similar things and due to their nature can be used in a range of different situations. It is important to check which tests the MFT can perform before you purchase one.
Multifunction testers perform a variety of tests, including:
Multifunction testers are used by electrical engineers for electrical installation work to verify and maintain electrical installations and that the required safety regulations have been reached in both commercial and industrial applications.
