Extech EX505 Overview

A bit of background on Extech before we look at the item itself; they are one of the largest suppliers of testing equipment worldwide. As such, customer service and satisfaction rank highly amongst their priorities and this feeds directly into the product we have today.

A model that is built for professional use on a daily basis, it comes with a durable and sturdy design that ensures it can be used repeatedly.

The top feature of this product has to be its versatility. You are able to measure capacitance, frequency, temperature and more. In conjunction, there are a whopping 11 functions to select which will fulfill most needs.

We will be going in depth with the item and explore what it's about with an overview, this will be followed by the key features, before moving on to our pros and cons.

We'll also take a look at what other users found when buying the product before giving our final verdict.

Extech EX505 Multimeter

This well designed and robust product is aimed at the professional in the industry. Due to its multiple functions, it would be unwise for a beginner to purchase this, as it can be quite overwhelming.

Simplicity has been sacrificed for functionality, which is again why we would advise seeking an alternative product if you’re brand new to this industry. With that said, this model is designed for heavy-duty use throughout the day.

As we mentioned above, multiple features exist to get the job done. Another helpful component of this model is the auto-ranging feature (we will expand on this shortly in our specifications).

Finally, it’s worth noting that there is a 520 variant of this model which exists in order to deliver greater instrument count and accuracy. With that said, let’s get into the detail for this model, the 505 and see how it fares.

Specifications

The obvious stand out here is the price of this unit. Coming in at $91.98 on Amazon.com you could be thinking either this is a great deal, or what’s the catch? The following list of specifications and explanations will be able to shed some light on this.

To expand further, here are some quick-fire functions to be analyzed.

1. Auto Ranging

The EX505’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 EX505 uses a more advanced True RMS calculation to compensate for this kind of distortion for superior performance.


2. Display

The screen for the 505 performs well. A 4000 count display is backed by bright LEDs. This may sound trivial to mention, but there are multimeters that don’t have this feature.

Unlike the Fluke models we have explored, where an issue with contrasting under certain angles is present, this model actually performs well under unfavorable angles.


3. Data Hold

In keeping with the above data hold function, the auto power off component is somewhat standard, but again is worth noting. ​

 simply concept, once the unit is inactive for a period of 15 minutes, it will shut itself off. The benefits are clear, not only will the battery power be saved, but time. You won’t have to remember to switch the unit off every time.

4. Auto Power Off

In keeping with the above data hold function, the auto power off component is somewhat standard, but again is worth noting.

A simply concept, once the unit is inactive for a period of 15 minutes, it will shut itself off. The benefits are clear, not only will the battery power be saved, but time. You won’t have to remember to switch the unit off every time.

Pros & Cons

A healthy list of specifics, but how did we rank the product overall? To be honest, it’s a good unit, but it’s not going to change the world.

There’s plenty to admire, and the features are numerous and work well, for the most part. The display is surprisingly good and reacts well in different lighting conditions.

The unit is also very durable and sturdy which is, of course, vital to the industry to withstand the occasional bump and drop.

The model is lightweight and compact, again a positive when you take into consideration how it will constantly be used in the day; you don’t want to carry around something heavy.

User Reviews: 

Our views have been expressed clearly here, so now it’s time to explore what other buyers said about this product.

 In the main, comments are generally positive with examples such as the following excerpt being commonplace; “This is a great meter. I use it for work every day and it take a real beating. The plastic case had taken the brunt of all of the falls and drops and does not show any signs of damage. The dial and buttons work perfectly and the screen is very easy to read with the large numbers.”


An interesting comparison was made with a Fluke model by one user, who examined that, “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.”


Further less than favorable reviews are offered with remarks such as, “Nice unit, however the continuity audible buzzer is very faint almost inaudible. The unit otherwise works well.”

Conclusion

The reviews above from other users indicate several key findings. Firstly, we can determine overall that the 505 is a worthy multimeter, but doesn’t quite tick all of the boxes necessary to make it a true top contender.

We discovered that the various features are both numerous and in the main, high performing. The poor aspect however was the temperature readout, which didn’t record as accurately as desired.

In addition, various buyers complained about the faint and almost inaudible buzzer, which was again in line with our discovery.  If you are looking to purchase this product, it will be able to satisfy most needs on a daily basis and perform to a good standard, offering reliable and accurate data.

Other multimeters can be prone to expiring due to be left on for too long, but thankfully this is not the case here. An auto shut off feature prevents this, which we found extremely useful.

Overall, we can ascertain this is a good product, but not without its flaws. For that reason, we would suggest opting for an alternative model, perhaps the 525 variant as this records data more accurately.
