When it comes to choosing between the Fluke 323 and 324 models, it can be tricky to decide which one is the better choice. Both models have their own unique features and benefits that make them great options for different situations. Below we will discuss each model to help you decide which one is right for you.

Fluke 323 Multimeter Overview

We shall begin with an overview of the Fluke 323 multimeter before comparing it to the 324 model. The 323 is a true-rms multimeter that can be used for a variety of applications. It is great for measuring AC current, AC voltage, DC voltage, and resistance. And it offers so much more.


The design of the Fluke 323 is such that it is extremely easy to use. The multimeter has a clear and large display, making it easy to see your readings. The buttons are also big and clearly labeled, so you won’t have any trouble operating the multimeter.

Fluke 323 is also noiseless, making it perfect for use in environments where you need to take measurements without disturbing others.

The 323 model comes with an audible sensor that can be used to detect electrical impulses. This is a great feature for electricians who need to find hidden wiring or for mechanics who want to locate the source of a noise.

323 is also very lightweight and portable, making it easy to take with you wherever you go. It even comes with its own case for easy storage and transport. However we found out that it’s a bit too tight of a fit.


The AC current range is one of the most important specs to consider when choosing a multimeter. The higher the current range, the more accurate the readings will be.

The AC current range on the 323 multimeter is 400.0 A with frequency between 45 Hz to 65 Hz. This range is great for a variety of applications, including measuring household appliances and electrical wiring. As for resistance, the 323 has a range of between 400Ω 4000 Ω.

The 323 can also measure continuity of less than 70Ω. This is a great feature for checking electrical wiring and connections.


Accuracy is critical for multimeters. If a multimeter is not accurate, the measurements it takes will not be useful. This can lead to problems in the electrical system that the electrician is working on.

The 323 offers an impressive 2.5% ± 5 digits accuracy, making it one of the most accurate multimeters on the market. This means that you can trust the readings you get from this multimeter, and you won’t have to worry about them being off by a large margin.

Being a True RMS multimeter, the 323 is also great for measuring AC voltage. This gives this device an upper hand over other multimeters that don’t have this feature.


Of course you want to be able to see your measurements clearly. The 323 multimeter has a large display that makes it easy to navigate through readings and settings. The digits on the display are nice and large, so you won’t have to strain your eyes to see what you’re measuring.

Unfortunately, the 323 comes without a backlight. This can make it difficult to see the display in low-light conditions.

Hold function

The 323 model has a hold function which allows you to “freeze” the reading on the screen. This is helpful if you need to take a closer look at the reading or if you need to step away from the meter for a moment.


Safety is always important when working with electricity. Both the 323 and 324 models have safety features that make them safe to use. Each multimeter has a CAT III 600V/ CAT IV 300V ratings. These ratings mean that the multimeters can be used in environments with up to 600 volts of alternating current or 300 volts of direct current.


Finally, we come to a price. The 323 multimeter is very reasonably priced, especially considering all of the features it offers. It is a great choice for electricians and other professionals who need an accurate and reliable multimeter that is easy to use. The Fluke 323 is available for purchase on Amazon for around $120. Keep an eye on sales and you may be able to get it for even less. [1], [2], [3]

Fluke 324 Multimeter Overview

Now that we’ve taken a look at the Fluke 323, let’s compare it to the 324 model. While these two devices are similar, there are some important differences to be aware of.


Just like with the 323, we will begin by inspecting the design of the 324. This multimeter is also rugged and reliable, built to withstand tough conditions. The buttons are also well-organized and intuitive, making it easy to use even for complex measurements.

It’s a bit bulkier than the 323, however, weighing in at 0.600 pounds. This is still a relatively lightweight multimeter, but it’s worth considering if you’ll be carrying it around with you a lot.

Fluke 324 too comes with an audible sensor that allows you to track whether or not the wire has electricity running through it. This is a great safety feature, as it can help you avoid shocking yourself accidentally.

Fluke 324 Multimeter Overview

The product also comes with a neat carrying case that fits everything snugly. This is great for keeping everything organized, and it’s also helpful if you’re taking the multimeter with you on the go.


When it comes to ranges, the Fluke 324 has a bit more freedom than the 323. It too can measure AC current between 40.00 A and 400.0 A, but has frequency ranges of between 45 Hz to 400 Hz.

As for resistance, the 324’s range is identical to the 323. It can measure anything between 400.0 Ω and 4.000Ω.

And just like the 323, 324 can measure continuity of <30 Ω. So with this multimeter it’s easy to tell if something is working as intended or not.

Additionally, the 324 has temperature measurements in both Celsius and Fahrenheit. It can measure between -10°C and 400°C, making it ideal for a variety of applications. This is very useful if you’re working with HVAC systems, for example.


Where the 324 really shines is in its accuracy. This multimeter is accurate to within 1.5% ± 5 digits, while the 323 is only accurate to within 2.5%. That means that if you’re measuring something with a lot of precision, the 324 is going to give you a more accurate reading.

Just like the 323, Fluke 324 is a True-RMS multimeter, meaning it can take accurate readings of both AC and DC signals. This is a vital feature for anyone who needs to take measurements of both types of signals.


The 324 has a large, easy-to-read display that shows more information at a glance than the 323. This can be helpful when working with complex electrical systems. But the feature that puts the 324 in clear display superiority is the backlight.

The 324’s backlight makes it much easier to use in low-light conditions, whereas the 323’s display can be difficult to read in anything other than direct sunlight.

Hold function

One of the most notable features of the 324 is the hold function. This allows you to take a reading and then freeze the display so that you can take your time writing it down. This can be extremely helpful when you’re dealing with fast-moving or hard-to-reach targets.

Fluke 324 Multimeter Overview


Now let’s take a look at the price. The Fluke 324 retails for around $240, while the 323 can be found for as little as $120. That’s a significant difference, and it’s worth considering if you’re on a tight budget. [1], [2], [3]


What is a Fluke 323 used for?

The Fluke 323 is a true-rms clamp meter that is used to measure ac current in electrical circuits without having to interrupt the circuit and attach test leads.

It can also measure dc voltage, resistance, and continuity.

Is the Fluke 324 worth the money?

The Fluke 324 is one of the more expensive models in the company’s line-up, but it’s also one of the most feature-rich. If you need all the bells and whistles that this multimeter has to offer, then it’s definitely worth the investment. However, if you don’t think you’ll use all of its features, you might be better off with a cheaper model.

Does the Fluke 323 measure temperature?

Sadly, the Fluke 323 does not measure temperature. If you’re looking for a multimeter that does measure temperature, then you’ll want to consider the Fluke 324 instead. The 324 is almost identical to the 323, but with the addition of a built-in temperature sensor.

Does the Fluke 323 have a backlight?

The Fluke 323 does not have a backlight. However, the Fluke 324 does have a backlight. If you need a multimeter with a backlight, the Fluke 324 is the better choice.

Backlight is important if you need to take measurements in low-light conditions. The backlight on the Fluke 324 makes it easier to see the display and take accurate measurements.
