    • The only Klein I found to work on HVAC
Size: 1 1/2-Inch Jaw
I needed to measure inrush current, and every Klein I ordered wouldn't do it (using MIN/MAX function) until I ordered this one. I guess because "HVAC" is in its title, that's what it was made for. Can't speak for its other qualities, but it DEFINITELY can measure inrush current on a compressor run wire. ... show more

    • Great value
Size: 1 1/2-Inch Jaw
One of the best brands out there. Great value and fast delivery. This bad boy has so many functions that I couldn't be any happier.

    • Nice clamp meter for the home dyi jobs
Size: 1 1/2-Inch Jaw
Been looking at a clamp meter for some time. Didn’t no which one would be a good buy. Watched several videos and this one seemed the best for me. Used it for some electric work on my house, doing some wiring for a portable generator and putting in a soft start on ac unit. Came with a nice case and some test leads and batteries. For the price and functions it works for what I need it for. ... show more

    • More than any regular homeowner will ever need
Size: 1 1/2-Inch Jaw
Purchase this because I recently installed a Generac generator and I wanted to be able to take readings on my air conditioning system and my generator as well as other appliances from time to time. I also do some minor electrical work around the house and often need to do continuity tests and other AC and DC testing. I will also be attending the Generac University generator technicians course to run a side hustle business maintaining generators so this is perfect for me but it is definitely more than anyone who is just a standard homeowner will ever need. If you want a high quality tool still then I highly recommend this because you should never need another tool as long as it keeps working. Really nice padded case comes with it also which is different from every low end $35 and under meter I have ever purchased. If higher end accuracy in your readings is something that's extremely important then it's worth the money. My Harbor Freight Tools higher end version of their product does not read the same as this. The HFT gauge reads about two amps higher when clamped to the same wire. ... show more

    • This is a great addition to my meter group
Size: 1 1/2-Inch Jaw
I bought this as it serves a couple of purposes. Mainly I use it to check the inrush current on both outside HVAC units before and after soft starts being added. It also serves as a nice DMM.
