  • Great Kit for the non-professional DYIer
Size: 3-Tool Kit
The Klein CL320KIT is a very good kit for the non-professional that wants to be able to troubleshoot electrical problems and possibly solve these problems without calling for professional help. I have both a home and a travel trailer that give me ample opportunity to use the multimeter and the NCVT. With this set and YouTube videos to guide me I’ve solved problems that would have cost me hundreds of $$$ in professional bills. Finally, my Kit seems well built and comes in a nice case that keeps everything well organized. ... show more

  • Great Meter at Good Price
Size: 3-Tool Kit
I do a fair amount of repair work, including HVAC and automotive. I wanted an accurate and well built meter for electrical troubleshooting. I am not a full time repair tech and did not want to spend unnecessary money on a Fieldpiece or Fluke meter. This Klein meter is just right for my needs. The included digital thermometer and electric sensor work well enough and are welcomed included accessories. These all fit nicely in the included zip case. My only gripes are the rear magnetic hanger is not included and must be purchased extra and the lead wire probes do not have push-on alligator clips included. Overall, I highly recommend this meter set for the money spent! ... show more

  • Excellent quality! High value for your money!
Size: 3-Tool Kit
I am in college for HVAC technician and I highly recommend this kit to get started with. Klein tools have generously provided a digital thermometer inside the kit as well. Saving me time trying to buy it separately. The digital thermometer alone makes my instructor jealous lol. He wants to take it and use it in class and that alone tells you that the quality is great! Thank you Klein tools for giving me leverage in my career field. ... show more

  • Affordable, decent quality
Size: 3-Tool Kit
Great set for the price, covers all of your basics for hvac work if you’re just starting out. Everything is pretty accurate, my only complaint is that the meter has always seemed to be a little off when compared to other meters. It’s a small difference, this meter might read 218v while other brands will read 220v for instance. ... show more

  • Good quality.
Size: 3-Tool Kit
This is a good kit, even though I don’t use it for HVAC. I like the non-contact voltage tester/flashlight, especially the lower voltage mode. Those curious about the temperature of a variety of things will like the infrared/probe thermometer. The non-contact voltage tester and the probe holder in the clamp are nice features. The meter itself seems to constantly try to auto-range, so sometimes its difficult to get a reading if you can’t hold the probes steady enough or there’s not enough surface area. I also wish it measured regular DC amps, and came with alligator clamp probe adapters. ... show more
