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 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 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 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 Steve 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 5.0 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.

Rated 5.0 out of 5.0 by LosRubios Fully featured, comprehensive multimeter set for the pro or the DIYer
I decided to try out this Extech meter kit as an upgrade to my old multimeter. This is a very high quality multi meter and clamp meter that also measures temperature in addition to voltage, continuity and capacitance etc. After several varied electrical jobs over the past couple of months, I would rate these as very high quality meters that are a great addition for any pro or weekend warrior who is taking on any electrical job, large or small, on the house, car, boat etc.
There were some features on the meters that I really liked including:
1. If you're working in a poorly lit area, the display has a backlight that can be switched on to get a better view of the data on the LCD. The display itself presentes large, easy to read numbers.
2. The probes have removable 'tip guards' which means you can get better control of where the tip is making contact (for finer measurements like the pins on a 2.1v DC power connector) and by removing the tips you get a longer reach for bigger jobs (like probing the contacts in a 220v receptacle to make sure the breaker has both sides de-powered).
3. The DMM meter has a stand that makes it easier to concentrate on placing the probes and reading the results instead of figuring out how to balance the meter in one hand and the probes in the other hand.
4. There is a built in slot in the back of the meter which holds the probes safely in place when not in use so you don't end up walking around with probe wires hanging by your ankles.
5. The units are supplied with batteries already fitted, so they're ready to go out of the box
6. They come with a soft sided tool wallet to make storage easier.
7. The meters come with very comprehensive printed manuals to explain how to use the various features properly
In addition to measuring the basic AC/DC, continuity etc. the meter also measures more advanced features like capacitance. This actually saved me about $200 when the a/c unit on our Acura failed. I was able to take the a/c control board out of the dash and test the capacitors. Instead of the $200 to repair the a/c board (or the $900 to replace the whole a/c control head unit), I was able to spend $3 for replacement capacitors to replace the ones that had failed and the a/c was back up and running again.
With the a/c repaired, as it was a couple of months since the a/c unit had broken in the late summer, I was then able to put the temperature probe in the a/c vents to confirm that the air was still cold using the supplied temperature probe. You could also do the same in the house if you wanted to test the temperature of your forced air conditioning.
