As you can see, the GW Instek GDM-8351 has the highest basic accuracy, the most measurement functions, and the most auxiliary functions. It also has a dual display, which can be helpful for viewing multiple measurements at once. However, it is also the most expensive of the three multimeters.

The UNI-T UT61E is a less expensive option that still offers a good range of features. It has a lower basic accuracy than the GDM-8351, but it still has a good selection of measurement functions and auxiliary functions. It also has a RS-232C port, but it does not have a USB port.

The Mastech MS8209B is the least expensive of the three multimeters. It has a lower basic accuracy and fewer measurement functions than the other two multimeters. However, it still has a RS-232C port and a USB port.

Ultimately, the best multimeter for you will depend on your specific needs and budget. If you need the highest possible accuracy and the most features, then the GW Instek GDM-8351 is the best option. If you are looking for a more affordable multimeter with a good range of features, then the UNI-T UT61E is a good choice. And if you are on a tight budget and only need the most basic features, then the Mastech MS8209B is a good option.
