Digital Multimeters | Voltage & Current Testing Tools

Digital Multimeters for Electrical Testing
Digital multimeters are essential diagnostic instruments for measuring voltage, current, resistance, and continuity in electrical circuits. These versatile testing tools provide accurate readings with digital displays, making them indispensable for electricians, technicians, and electronics enthusiasts.

Key Measurement Functions
Modern digital multimeters measure AC and DC voltage up to 1000V, current from microamps to 10A or more, and resistance from ohms to megaohms. Many models include additional functions such as capacitance testing, frequency measurement, temperature sensing, and diode testing capabilities.

Auto-Ranging and True RMS Technology
Auto-ranging digital multimeters automatically select the appropriate measurement range, eliminating manual range switching and reducing measurement errors. True RMS models accurately measure non-sinusoidal waveforms found in modern electronic equipment with variable frequency drives and switching power supplies.

Safety Ratings and Certifications
Professional digital multimeters carry CAT (Category) safety ratings from CAT I to CAT IV, indicating the maximum voltage and transient protection level. CAT III and CAT IV rated meters are designed for industrial environments and power distribution systems, featuring fused inputs and overload protection.

Display and Data Features
Digital multimeters feature LCD displays with count ratings from 2000 to 60,000 counts, determining measurement resolution. Advanced models offer backlit displays, data hold functions, min/max recording, and Bluetooth connectivity for logging measurements to smartphones or computers.
