As you can see, the Uni-T UT231 is the most affordable multimeter of the three. It also has a 3.5-digit LCD display, which is not as high-resolution as the 4.0-digit displays of the Fluke 117 and Mastech M320A. However, the UT231 is still accurate to ±0.5%, which is sufficient for most general-purpose measurements.

The Fluke 117 is more expensive than the Uni-T UT231, but it has a higher-resolution display and a wider range of measurement functions. It also has a longer warranty period of 3 years, compared to the 2-year warranty of the UT231.

The Mastech M320A is the least expensive multimeter of the three, but it has a lower-resolution display and a narrower range of measurement functions than the other two multimeters. However, it is still accurate to ±1.0%, which is sufficient for most general-purpose measurements.

Ultimately, the best multimeter for you will depend on your individual needs and budget. If you are looking for an affordable multimeter with basic measurement functions, the Uni-T UT231 is a good option. If you need a multimeter with a higher-resolution display and a wider range of measurement functions, the Fluke 117 is a better choice. And if you are on a tight budget, the Mastech M320A is a good option for basic measurements.
