Multifunctional testers
Electrical Installations Safety
Electrical installation safety is nowadays more important than ever with the proliferation of increasingly complex domestic electronic appliances people install in their homes that require reliable power supply lest they become damaged and pose a fire and electrocution risk. Effects of unreliable and even dangerous electrical installations are even more acutely felt in industrial environments where they translate into production losses.
Metrel offers a wide range of multifunctional electrical installation safety testers suitable for testing domestic and industrial electrical installations. They offer a versatile solution for virtually all installation safety testing by combining an array of functionalities and features in a single rugged device, enhanced with a myriad of accessories for even the most specialized applications.
