Rated 5.0 out of 5.0 by SouthernUtahBoy 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 5.0 out of 5.0 by 2gtsvette 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 5.0 out of 5.0 by JohnS A full and complete Industrial kit.
The Extech test kit contains two full and complete test meters with all associated accessories, such as test leads, probes, adapters, and hang strap. And it all fits into a single zippered pouch/case.
The meters themselves are industrial, so are waterproof and ruggedized. Large, easy-to-read displays; responsive buttons; loads of features. These models are the higher-end models of the line-up. (The only thing these don't have is wireless technology like Bluetooth.) They both use 9V batteries and require a screwdriver to change. (Wish it was the more-common AA with tool-less change.)
The clamp meter is a True RMS clamp with non-contact voltage detector (very useful). Easy-dial thumb control for selecting functions.
The multimeter is also True RMS with test leads that connect easily. Just dial the function you need. Has a stand, probe-holder and attachable strap.
The kit comes with two manuals that are well-written and allow you to easily find the function you need. After a few uses you will have it figured out. The manuals are really thick because there are 6 languages in at least one of the manuals. I wish they were all separate so I can throw away the languages I don't need. Also I wish there was a place to put the manuals in the case; I have to set them on top of the meters.
Finally, there's extra room in the case for other accessories. I plan to add some immersion probes and such. This is the best kit that Extech has. So if you want to obtain a single kit with the better industrial meters all in one carry-case, this is it.

Rated 5.0 out of 5.0 by Daniel Ready to go out of the box!
The meter was ready out of the box, but it took me two intro videos to learn how to correct use the meters. I have used small meters in the past. This is a quality unit I'm proud to add to my tool box.

Overall both of these meters are quite good. I do wish that the documentation was a bit better as nowhere in the manual or online I was able to find exactly how they want you to use the magnetic holder. I am sure I will find a way I like to rig it up but it is ceirtainly not as clear or easy as some of the leading competing products.
The meters are provided in a nice case and with a set of leads and temp probe for each meter so they can go off on their own. The clamp meter has a built in non-contact voltage detector which is always nice to have handy to make sure that there is in fact no power in whatever you are about to touch.
One thing I did not like is that the temperature probe has some very odd accuracy properties. Basically, as far as I can tell, the reading will always be offset by a 9 deg F in addition to the +/- 3% error. I put a picture of the manual along with this review so you can see for yourself.

Rated 5.0 out of 5.0 by JamesC Very nice meter set. Easy to use. Accurate.
I put these meters through their paces and my conclusion is that overall, this is a very nice set of testers. The meters are fairly easy to use and the readings they gave were accurate. Batteries came preinstalled, allowing for use of the meters as soon as I removed them from their box and soft case. Each meter features a large LED display that is easy to read, even in low light due to backlighting. A rubberized exterior case provides for a positive grip and is ruggedized against accidental drops and damage. The K-type test leads and temperature probe fit snugly into their respective receptacles on the digital multi multimeter (DMM) and don’t accidentally fall out during use. The included nylon carrying case serves to keep the meters and accessories neatly organized and protected against damage during travel and storage. As a firm believer in safety and the use of proper tools for the job, especially when it comes to anything electrical, this kit is a must-have for any electrician, contractor, home inspector, or DIY homeowner as it allows you to quickly and safely determine if electrical wires and receptacles are live, as well as to troubleshoot problems. By troubleshooting problems myself, I have saved thousands of dollars by not having to hire a professional. The AC clamp meter allows you to safely test high amp electrical wires (up to 1-1/2 inch diameter), without contact, to determine the presence of voltage, while the DMM is able to tests for basic capacitance (amps, volts and ohms), temperature, frequency and continuity. The clamp meter allows you to quickly take a measurement of the current being induced through a wire without interrupting the circuit. Use of the clamp meter however, relies on direct access to the wire. More often than not, I don’t have access to the wire, such as in the case of underground wires or wires buried in a wall, but with this kit, I can still test the for current at the power supply, receptacle, or a fixture with the included DMM. While the clamp meter will give quick results, I find that a direct read via the DMM is more accurate. Typically, for high amps, you can’t use a DMM. This DMM is rated for 10 amps, but will handle applications up to 20 amps (for 30-secs). The knobs on the DMM and clamp meter are large and click positively into position with symbols that are easy to comprehend and buttons that feel solid when you push them. The DMM has a magnetic hanger so your hands are free to work and, after some period of non-use, both meters will automatically shut off to conserve battery life. The meters, and especially the DMM, is larger than I’d like for it to be, but I suppose that means they won’t get left behind at the job site or lost in my toolbox. Also, the DMM continuity beep sometimes sounds as if it’s straining or is unsure of itself, and the test leads are a bit short so you need to be close to your work. Minor quirks aside, these meters are quite capable of doing anything the more expensive meters can do, and are a very good value for the money. As a kit, there is a bit of cost savings benefit over purchasing the meters individually. IMO, the quality of meters in this test kit are on par with meters costing more than twice the price and should be a part of every toolkit.

Rated 5.0 out of 5.0 by freelyelee Great Set, Great Value
I'm not a professional or an electrician or anything fancy. I'm just your average DIY homeowner. This product appealed to me because on multiple occasions I had an issue with a faulty power switch that resulted in an unnecessary call to an electrician to see if there was power or not. The electrician used an item very similar to this so I figured why not?
- Pretty comprehensive set for the money (Complete set with everything you need- no extra cost associated with add on parts)
- Relatively straightforward to use. The instructions weren't totally helpful, but I was able to find a few videos. If you have any familiarity with these, should be easy to use. As a total novice, it wasn't impossible.
Great value for money and a really nice set for a homeowner. Has already paid for itself. Recommend!

Rated 5.0 out of 5.0 by Camano This is a great kit!
It comes in a canvas case with carry strap. Two sets of leads and two thermocouples are included. The meters come with batteries installed.
These meters have many functions in common, including measuring volts, ohms, capacitance, continuity, diode, temperature, duty cycle, and frequency; backlight, hold function, relative measurement function and auto power off.
The MA620 Clamp Meter is best for handheld use while installing or troubleshooting utility power.
The EX505 multimeter is best for desktop use troubleshooting electronics
I thought it would be helpful to list the differences between the two meters:
MA620 600 Amp AC True RMS Clamp Meter:
Non-contact voltage detector
Reads clamp-on AC current up to 600 amps (vs 10 amps using test leads)
Does not read DC current
Does not read AC current using test leads
Reads resistance up to 60Mohms (vs 40Mohms)
Reads capacitance up to 4000 microfarads (vs 100 microfarads)
Has a much smaller display
EX505 Autoranging True RMS Multimeter
Reads DC current up to 10 amps
Reads voltage up to 1000v (vs 600v)
Reads frequency from .001Hz to 10MHz (vs .01Hz to 10KHz)
Has test lead storage on back of case.
Has a built-on desk stand.
I do wish that the kit had included the Extech line splitter to allow measuring the current draw of plug-in appliances with the clamp meter.
