Digital Multimeter-Resistance Range:400Ohms, Temperature Range:-40 to 1000 Degree C

A digital multimeter (DMM) is a versatile electronic instrument that measures electrical voltage, current, resistance, and other electrical parameters. It typically consists of a display, selection knob, and probes for connecting to the measured circuit.

Digital multimeters use microprocessors and analog-to-digital converters to provide accurate and precise measurements. They are available in a wide range of models with varying levels of precision and features. Basic models typically measure voltage, current, and resistance, while more advanced models may offer additional features such as capacitance, frequency, and temperature measurement.

Digital multimeters are commonly used in various applications, including electrical and electronics troubleshooting, laboratory research, and industrial maintenance. They are compact, portable, and easy to use, making them ideal for professionals and hobbyists.

While digital multimeters are generally more expensive than analog multimeters, they offer advantages such as higher accuracy, better resolution, and greater versatility. Digital multimeters can also be more reliable, as they are less susceptible to drift and other sources of measurement error.
