As you can see, the Extech MG310 is the most affordable multimeter in this comparison. It is also accurate to ±1.0%, has auto-ranging, a backlit display, min/max hold, NCV, continuity buzzer, and is small and lightweight. However, it does not have the same level of accuracy as the Fluke 115 or Klein Tools MM200.

The Fluke 115 is the most accurate multimeter in this comparison, with an accuracy of ±0.5%. It also has a longer warranty (3 years vs. 1 year for the Extech MG310 and Klein Tools MM200). However, it is also more expensive and does not have a backlit display.

The Klein Tools MM200 is the most affordable multimeter with a backlit display in this comparison. It is also accurate to ±1.0% and has NCV, continuity buzzer, and min/max hold. However, it does not have auto-ranging.

Ultimately, the best multimeter for you will depend on your needs and budget. If you are looking for the most affordable multimeter with basic features, the Extech MG310 is a good option. If you need a more accurate multimeter with longer warranty, the Fluke 115 is a better choice.
