As you can see, the Voltcraft AT-400 is the most affordable of the three multimeters. It also has the highest display resolution and the widest range of voltage and current measurements. However, it does not have a CAT III rating, which means it is not as safe to use for high-voltage measurements.

The Mastech MS8208 is slightly more expensive than the Voltcraft AT-400, but it has a CAT III rating and a wider range of frequency and duty cycle measurements. It also has a slightly larger display.

The Uni-T UT61E is the most expensive of the three multimeters, but it has the widest range of resistance and capacitance measurements. It also has a built-in temperature probe and a data logging function.

Ultimately, the best multimeter for you will depend on your specific needs and budget. If you are looking for the most affordable multimeter with a high display resolution and a wide range of voltage and current measurements, then the Voltcraft AT-400 is a good option. If you need a multimeter with a CAT III rating or a wider range of frequency and duty cycle measurements, then the Mastech MS8208 is a better choice. And if you need a multimeter with the widest range of resistance and capacitance measurements, as well as a built-in temperature probe and a data logging function, then the Uni-T UT61E is the best option.
