Reviews: Fluke 323 True RMS Clamp Meter

Rated 2 out of 5 by from Not the quality I thought it would be ! Purchased model 323 used it twice and on third attempt the unit was dead! I owned it about 3 years, to be honest it spent most of its life on my boat. Totally disappointed I wanted a quality product, sorry for the bad news!

Rated 1 out of 5 by from 3 years old meter with a critical error Bought this meter 3 years ago maybe used 10 times. Went to use today First time in about a year. Meter came up with a critical error. Not what I expect from a fluke model. I would not buy Or recommend this fluke model. Fluke let me down when I needed it. I called fluke representative and was told out of warranty you got to buy another one I can’t help you. Buy another meter. Another meter that showed me dependability

Rated 4 out of 5 by from GOOD METER The meter price is reasonable, it is durable and reliable, but there are a few thing that keep it from being great one. The audible tone needs to MUCH louder and when the meter goes off (it has auto off) you have to rotate the function knob all the way back to the off position then back to the function you are using. Needs a on and off button or, the a function added such as rotate selector knob to the next function to activate it back on.

Rated 5 out of 5 by from Excellent Meter I bought this meter to use at work. My company supplies us with volt meters but they are not the quality of this Fluke meter. I have not found a meter as accurate as this one. You can not go wrong with this Fluke meter.

Rated 5 out of 5 by from Works as required I use the Fluke 323 as my go to meter for around the house. It is a little overkill for what I use it for, but as an Electrical Engineer - I like overkill with my electrical test equipment. I've used it for a few work related projects, it has never let me down.

Rated 4 out of 5 by from Great for the Price I've had this meter for a while and I can say it gets the job done. I really like the clamp, not only can you take amperage readings you can also use it to clamp on the equipment door for convenience. Meters are used for safety as well as information about the circuit and I can truly say I wouldn't trust my life with anything other than a Fluke!
