Which type of voltmeter is generally more precise for laboratory measurements?

A digital voltmeter is generally more precise for laboratory measurements due to its ability to provide a numerical readout that eliminates the parallax error commonly associated with analog voltmeters. Digital voltmeters display measurements in a clear, direct format, allowing for more accurate readings. They also often have higher resolution and sensitivity compared to their analog counterparts, enabling them to measure smaller voltage changes with greater accuracy.

In a laboratory setting, where precise measurements are critical for experiments and data collection, a digital voltmeter's features—such as automatic ranging and the ability to interface with computers for logging data—enhance its precision and reliability.
