Product overview: Fluke 373 True-RMS AC Clamp Meter
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 Ω.
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.

Rated 5 out of 5 by FreePower from Rock solid Fluke quality I've been through a number of multimeters in my lifetime and I've owned my Fluke 373 for four years now and it's still going strong despite regular use and, I have to admit, a fair amount of abuse. Well worth the money, especially considering it includes capacitance testing and the clamp meter function and, of course, the Fluke quality and durabilty. I'd gladly buy another one but I doubt I'll ever have to.

Rated 5 out of 5 by GFAOPS from Wastewater Tech I have the 373 model and LOVE IT! I use it while cycling the pumps on during my weekly rounds. Just this little step has helped me save clients money and work for myself. I can now see when the pump is running harder and can fix the issue prior to burning the pump up.
Thank you Fluke for your outstanding products and service.

Rated 4 out of 5 by Ken1 from Worked well for my application - battery leakage The 373 was working well for my application. I brought it to my lab for a demonstration and when I turned it on and nothing. I went to change the batteries and the Energizer Industrials leaked. Damaged the battery terminals but did not reach the main board. Fluke service provided part #s, but you cannot purchase the parts. I even offered to buy the entire back, again not offered. Disappointed they are not offered as a replacement part.
