Secure Tools supplies Digital Multimeters (DMMs). They are versatile electronic measuring instruments used to measure various electrical parameters in circuits and systems. They provide accurate and precise measurements of voltage, current, resistance, capacitance, frequency, temperature, and other electrical quantities. Digital Multimeters are called "digital" because they feature a digital display to present measurement readings in numerical form, making them easier to read and interpret compared to analog multimeters. They are widely used by electricians, technicians, engineers, and hobbyists for a wide range of applications in electronics, electrical systems, and troubleshooting tasks.
