Rated 5 out of 5 by from High qualtiy great value meters These are excellent meters, They come in a nice carrying case and both the amp and voltage meters have a ton of features and settings to test various circuits and components. The Amp meter has a nice Line voltage non contact light that lets you know which lines have power with out touching them. The housings on both meters have a nice grip and sturdy feel and should last several years. I do like the thermocouple features on both units that lets you view temperatures in real time with a decent accuracy. If you are looking for a great value meter set then you should not pass this by.

Rated 5 out of 5 by from Great Kit I got this kit for one of my crew members that didn't have any kind of a Tester/Meter. But after getting the kit we was in the shop looking over it and was showing him how to use the kit. I was doing a job and I was able to use the kit and I was very pleased with how great it is. I would not have any trouble with putting this great product up next to the high dollar units. I have a Great Number of EXTECH Products and I am very Thankful and Happy to have picked EXTECH Products to use on my #1 turn to. I carry EXTECH and I use there products everyday and I have never been let down by any of there products.

Rated 5 out of 5 by from Great combination of dmm and clamp meter! This meter set is a great value for what you get, I needed both types so this was perfect for my needs. I like that it comes with a soft case, and 3 sets of probes. One thing I like about the DMM is the large size of the display, making it very readable. As for the clamp meter, I appreciate that the clamp opens up wide enough to get over most wires. It's also not too thick so you can get it into tighter areas. The meter reads true RMS, so you know you're getting an accurate reading.

Rated 5 out of 5 by from Very versatile and accurate I have other multimeters and amp clamps and theses are as good as those if not better. I checked the accuracy of these against calibrated ones at work and they were right on. All in all this is a comprehensive set of quality meters. And its nice that it comes with a bag too, and a magnetic strap that I think is supposed to hold the meter, but its not nearly strong enough and there was nothing in the manual about it either. These have some extra features that I have not had the need to use, but can see them as being useful. -The hold function is a nice store a value. the peak is also a nice function (I am not sure how accurate it is but would assumes it's pretty decent as long as it's not something that happens in a fraction of a second like the surge of current when a motor starts) -frequency measurement -I understand what its for just have not had the need -capacitor readings -I understand what its for just have not had the need but could see where i could use it. -Thermal couple -I have other meters that can do this but did not come with the thermocouple, this comes with two.

Rated 5 out of 5 by from Right description, wrong image The kit pictured on this page is not the MA620-K described but rather the less expensive TK430. I've posted the correct image below. Although I'm not a licensed electrician I own rental properties and I do more than my fair share of diagnosing electronic problems, electrical repairs and electrical rough-ins. Dependable multi-meters and clamp meters are important tools for this trade. I burned up my current multi-meter, a cheapo from Harbor Freight, so I was in the market for a quality replacement at a reasonable price. While browsing the HD website I came across this Extech kit which included everything I was looking for. The Extech name was unknown to me but after reading the excellent reviews it received I decided to try it. It arrived quickly and everything was included as advertised. It ships with a nice nylon carry case with a full set of leads for both instruments. I haven't used it on a job site yet but I did have the chance to test all the features and everything works well. I like that the multi-meter includes a magnetized strap which allows the meter to hang, freeing both hands. Also, both meters have switchable back-light buttons, temperature probes, are auto or manual ranging and the clamp meter features a no-contact voltage detector. There are many features I'll probably never use but all the important ones are there. Well worth the money even for the casual user.

Rated 5 out of 5 by from Highly Versitile Meter set Extech MA620-K: Industrial DMM/Clamp Meter Test Kit The Extech Industrial Digital Multimeter and Clamp Meter is awesome. I’ve included pictures of the set. Included in the set are two meters the multimeter and clamp meter. I took a close up of the multimeter selection knob. I like how the voltage setting is just one selection and the mode button selects AC or DC. The set also comes with two k-type thermal couples for measuring temperature. There range is -30C to 300C. This is perfect for the science experiments my kids do. They’re working on a caloric measurement system for a candle water heater. Having the two thermal couples, one for the intake and one for the output makes this quite easy to calculate the energy put into the system. Also note that the ohm, diode, and cap are just one selection as well. The mode button switches between the modes. I love the display. It’s large and easy to read. The clamp meter is really nice as well. We are able to read current levels from our solar power project without breaking a line. Just clamp the meter around one wire and read the current. Also the meter has an AC voltage detector on the tip of the clamp. I find this very useful when working on the wiring in my house. I took a picture of me testing a line. I didn’t even have to take the wire nuts off to find out if the line was hot. The set comes with two sets of sharpies. Everything fits nicely in the package. I’ve included a picture below. I’ve had some meters that take work to get them back into the case. Extech has left plenty of room. The clamp meter also reads temperature, voltage, ohms, diode, and capacitance. Both meters have lighted displays at the touch of a button. This is really useful when I had to work on my boat trailer lights. This is one of my most useful tools. I take it on trips with me since there is always something in the boat or trailer that needs fixing. I recommend this product.

Rated 5 out of 5 by from The Absolute Last Meter Kit You’ll Ever Need! First: Note that the photo on the website at this writing is NOT the correct item. It shows a standalone non-contact voltage detector and a phase sequencing meter. Not the right product, at all. I own several digital meters, including a Fluke MM and a Klein clamp on ammeter. For over twenty years I’ve used that Fluke and always considered it to be the best. I bought the Klein when I needed to measure current draw on a heater in my workshop and that cost me over $100. Had this meter kit been available at the time I absolutely would have purchased it instead. To be 100% honest I have taken my Fluke and Klein out of my electrical bag, adding this kit in their place. Now I am considering selling the Klein and keeping the Fluke as a backup. As an owner of high end meters I absolutely love these meters! For a hard core DIY this kit has everything I could need. It’s amazing! The container is almost perfect. It’s compact and as small as they could get it while still holding the two meters and accessories. I love how contained it is. I think they could get away without including two sets of test leads and two temperature harnesses, but I’ll just take them out and keep them as spares, leaving more room in the bag so I don’t have to spend as much time folding up the test leads. I’m not going to iterate the list of technical features here because you can get that list easily enough. I will say that they’re PACKED with features and I’ve been having a blast experimenting with them. Temperature! Frequency! Capacitance. Non-contact voltage detection. The controls are we well laid out and the interface is straightforward, which is important. Of course, they’re auto-ranging. The backlit display is nice! I’ve reviewed other EXTECH meters and now own several. I love them. They really seem to be pumping out a fantastic set of meters that look good, feel good, work well and have a ton of features. These meters are no exceptions. Fantastic product and price!
