Product By Flir Logo

Fluke 373 True RMS AC Clamp Meter does the job for any AC-only current measurement application

Fluke 373 True-RMS AC Clamp Meter is a great choice for AC-only current measurement situations. Featuring True RMS AC voltage and current measurements you can measure AC current to 600 A and AC voltage to 600V. The 373 also measures DC voltage to 600 V and resistance to 6000 ?.

To make it even easier to use, the large, easy-to-read backlit display provides better visibility in dimly lit conditions. And the 373 automatically sets the correct measurement range based on the voltage present when you power up, so you do not need to move the switch while taking a measurement. When you put it all together, you’ll find the Fluke 373 offers everything you need, plus a little more.

Other useful capabilities:

  • Provides True-RMS voltage and current measurements to accurately measure non-linear signals
  • Automatically selects a measurement range based on voltage present so you don’t need to change the switch positions while taking a measurement
  • Presents readings on a large, easy-to-read backlit display
  • Features CAT IV 300 V, CAT III 600 V safety ratings
  • Comes with a soft carrying case and three-year warranty
  • Runs on two AA alkaline batteries
