As you can see, the Fluke 381 and Fluke 376 FC are very similar multimeters. They both have true RMS measurement, a wide range of measurement capabilities, and a durable construction. The main difference between the two meters is that the Fluke 381 has a detachable display, while the Fluke 376 FC does not. The detachable display on the Fluke 381 can be helpful for taking measurements in difficult-to-reach places or for viewing measurements from a safe distance.

The Fluke 375 FC is a less expensive multimeter than the Fluke 381 and Fluke 376 FC. It does not have a detachable display, but it does have all of the same measurement capabilities. The Fluke 375 FC is a good choice for electricians and other professionals who need a reliable and accurate multimeter without the extra features of the Fluke 381 or Fluke 376 FC.

Ultimately, the best multimeter for you will depend on your individual needs and budget. If you need a multimeter with a detachable display, the Fluke 381 is a good option. If you are looking for a less expensive multimeter with all of the same measurement capabilities, the Fluke 375 FC is a good choice.
