The Extech EX530 is specifically designed for industrial, MRO, electrical and other professionals who need a heavy-duty, feature-rich multimeter. The EX530 is capable of taking numerous measurements including capacitance, frequency (dual sensitivity for electrical and electronic applications), diode test and continuity.

The EX530’s auto-ranging capabilities allow it to automatically adjust the measurement range based on the detected source, such as electrical components and electronic equipment. In some commercial and industrial environments where electronic devices are present, the AC waveform can be distorted, making it difficult for averaging meters to get an accurate reading. The EX530 uses a more advanced True RMS calculation to compensate for this kind of distortion for superior performance.

OK,

I am not an electrician but like and routinely use multimeters with automotive modifications and home remodeling projects around the house. First this is more meter than I require but when it comes to electricity, I dont want to skimp on a cheaper unit. I did a weeks worth of reviewing Fluke models, Klein, Greenlee, etc and decided this one was the best entry professional model for the money. I want to ensure I got a true RMS MM and teh Waterproof rating was a plus. What sold me on this was not only the features and price, but many reviews here and the YouTube video Extech has for the 500 series meters. It is a must see but lets just say these are rugged and accurate. I also wanted to ensure I bought one that covered the entire range for CAT III and entry CAT IV. It does all the conversions for DC for you and that was a must since I use it on authomotive as well.

It comes with a nice case, with storage room for a few other leads and will help protect it although probably unessary.

I can say, buy with confidence and I bet I will get years of use out of it. Oh, Also bought the Extech MA640 True RMS AC/DC 600A Clamp Meter with Non-Contact Voltage Detector the day after getting this one. If you want a GREAT Clamp meter that does a lot of what this one does without purchasing two MMs, I would recommend it. Probably overkill for me to have both but that is how I roll.

I spent a good couple of nights researching $100 plus+ meters and decided on this one. I found it to be a real value in this price range and upon receiving it was impressed with the overall sturdy feel it had it my hands and the added features that I was skeptical to pay up for when I first was looking to purchase in this price range. I absolutely love this meter and have NO REGRETS about getting a true RMS meter with these added features. You''ll love the temp feature for HVAC work and auto repair and will be amazed at how fast it reacts to temp changes even though I haven''t confirmed the accuracy of this feature yet. I am extremely pleased with it and will use all features of this meter. The only negative issue I''ve found, (just me nitpicking) is the large knob on the face that switches between functions doesn''t seem to have a positive detent click and smoothness when turned as compared to the higher end Fluke models as well as the lead/probes not being top shelf but plenty sufficient and rated for cat.3 and cat.4 work. You''ll love it for the value!!!

After reading a number of negative reviews about the EX505 I was prepared to be disappointed. The first thing I did was to remove the six screws holding the back on & examine the printed circuit board - very nice soldering, good component placement, etc. After attaching the back I took AC & DC volt measurements, DC amp measurements, ohms, frequency, etc. All read comparable to my Fluke 179.

The only negative (compared to my $300 Fluke) is that the meter takes between two & four seconds to settle down to a voltage reading - the Fluke reads instantly.

Two sets of test leads are included & both use 2000 volt insulated wire. Test lead ends are shrouded to prevent shock, just like Fluke. A similar test lead set from Fluke is $75 so the additional leads & tips are significant.

The magnet hanger isn''t as powerful as Fluke''s but it holds the meter as long as the surface is flat & clean. The supplied black nylon strap doesn''t fit really well so I replaced it with a 5/8" wide dog collar - much nicer fit & the meter hangs straight (see image)

The non contact voltage tester works well & is very sensitive. There''s a tiny LED flashlight built in but it''s pretty weak.

The case isn''t anything special but it does provide storage for all components. Again this is an extra cost item from many manufacturers.

All in all a solid value.

While it worked it was a good DMM. As other people reported, the continuity test was slow. I bought it six years ago and paid extra as it says it is ''heavy duty''.
I am a hobbyist and used this multi-meter once a month or even less so I thought it would last forever.
One day I pick it up to measure continuity on a project, and the selection knob breaks internally and this DMM becomes an expensive paperweight.
I am trying to find how much it would cost to get a repair, but the site that Extech points to for repairs (Flir) is clumsy and I have not been able to create an account - which is required even before you get to any useful information. So much for wanting to buy a quality product that would last.

Stand it up on it angle arm and it''s super wobbly! The bottom of the meter is rounded and the arm is narrow. Expect your meter to fall over a LOT if you stand it up. I added a flat base to mine. This is REALLY annoying!

The lead wires feel a little cheap compared to more expensive meters, but they have held up well and I would definitely buy this meter again, especially since working on boats the water resistance is an important thing for me and better brands of meters don’t offer water resistance at a price point anywhere near this one.

The Extech EX505 is a very high quality DMM with many features. It is accurate and is solidly built. The unit is water proof and ruggedized and can be dropped without damage. I have used the higher priced Fluke meters in the past and they are the best, but to purchase an equivalent ruggedized Fluke meter would cost more than twice the price. This meter could easily meet the needs of all but the most demanding field technicians. I purchased this meter from Amazon with an Extech promotional coupon and paid a very a very reasonable price. Considering the price and performance of this RMS DMM you can''t go wrong. I would highly recommend this meter, even for professional applications.

The only complaint I had was the test leads are too short. If all you do is bench work, they''d be fine, but if all you do is bench work, you''d probably be using a bench meter anyway. I had to order new leads, alligator clips, and plunger style hook clips to complete the package. Many meters come with alligator clips, but this meter is built to take abuse and it sold me on that feature. I happily paid the extra for the longer leads, etc.

Cons: A/C Voltage reading takes several seconds, very annoying when I was testing power at 16 360V fuses in a parts washer at work. Ohm Function was completely non-functional, reading jumping between 0 and 60,000 ohms while leads firmly touching, reading did not settle and kept jumping around. I opened the meter to inspect=no fault found, however, overall build quality is low, components are loosely mounted, Especially the Infrared Temperature Sensor Component I tried a separate set of test leads=ohm function works fine Found the positive test lead that came with the meter had a chrome-like coating, apparently non-conductive.=Junk The Continuity/Beep Function is very slow(even with good leads), basically non-usable as the purpose of the beep test is to quickly check several terminals/measurement points with an instant beep to indicate closed circuit.=this function on this unit is junk. As a mechanic, a proper/instant beep test function is one of the most important functions in a multimeter. Pros: Decent Display Resolution Amazon has a great return policy, no questions asked. I sent this poor quality piece of crap back! Thank you Amazon!
