    • 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

    • Not just for Hvac
Size: 3-Tool Kit
Review Image by Franky J
The case is cheap. The tool and attachments get beat up pretty bad in the case that comes with the set. Had to purchase an aftermarket hard case for real trade use. Definitely worth another $16. The temp probe is ultra useful. Love the temperature feature on this meter. The biotherm is useful as well but not my go to for hot applications. I also purchased the optional magnet attachment so that I can really work with this unit hands free. The NCV detector is only useful to track down shorts in wires otherwise the meters built in NCV trumps the little pen NCV detector. Overall great set. I’m not an HVAC tech. Although, I work with single, double, triple, and quad phase electrical applications on commercial equipment. ... show more

    • 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

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

    • Super great kit.
Size: 3-Tool Kit
I use everything in this kit. I love the temp probe. Can be used in so many ways. The continuity tester works perfect for quick checks. The meter is extremely accurate and very reliable. I love that it has a backlight for the screen when in dark areas. I would recommend this to anyone in need.
