Fluke multimeters may look similar but are way different in terms of specifications and pricing. The three most popular models from Fluke are 175, 177, and 179. My aim is to provide separate reviews of fluke 175, fluke 177, and fluke 179. All of these meters belong to the same 170 series of Fluke but have different specifications. Keeping in mind this, I will make a side-by-side comparison of Fluke 175 vs 177 vs 179. So, before comparing let's check each fluke multimeter specifications individually.

Fluke 175 Multimeter Review

It is considered as the basic variant of the fluke 170 series. Although you can get almost everything done with fluke 175. One of the most prominent features of fluke 175 is its analog bar with a 40times per second update rate. Apart from this, it comes with a large digital display which makes the reading easier.

As it's a true RMS Multimeter so you measure almost every AC voltage and current. This quality is very important for HVAC applications. Moreover, it comes with low input impedance which makes it suitable for measuring voltages of non-linear loads like motors, fans, and VFDs. If you want to know more about how to test VFD then I have made a separate guide for you.
