  • Great product
Size: 3-Tool Test Kit
Great deal . Always trust klein when dealing with electrical!

  • Great Meter at Good Price
Size: 3-Tool Test 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

  • Super great kit.
Size: 3-Tool Test 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.

  • It almost works works perfect.
Size: 3-Tool Test Kit
Good kit. The thermister that plugs into the meter has a short in it (its cheaply made). Other than that is all works. Good starter kit for a HVAC apprentice or DIYer.

  • This is a very nice clamp meter
Size: 3-Tool Test Kit
I regret getting this because it doesn't measure inrush. If you need to measure inrush get the CL445. Otherwise this is a good meter, and I think you will like it.

  • Not just for Hvac
Size: 3-Tool Test Kit
The media could not be loaded. 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
