Factors we considered for choosing the best multimeters
Before pulling your credit card out to invest in a multimeter, there are certain things that you need to take into consideration.
1. Resolution
The resolution of a multimeter, particularly of a digital one, is the number of counts it shows. You should consider choosing a device with a high resolution so you will get more exact results. This is a great tip to follow by beginners who need exact readings in order to make fewer assumptions. Plus, a high resolution can save you of a lot of unnecessary work.
2. Voltage and resistance range.
All multimeters can measure up to a certain voltage and resistance value. The larger these ranges are, the better for you. Choosing a device that measures the same range in AC and DC can only work to your advantage. And if this range is large, you can definitely use it for more purposes and measurements which increases its functionality.
3. Accuracy
You will see in each description that multimeters come with a certain accuracy regarding the voltage and resistance measurements. You want this accuracy to be as exact as possible so you can rely on the readings the device gives you.
4. Price
These devices range from hundreds of dollars and thousands of dollars. Ultimately, it is up to the budget that you have but keep in mind that digital multimeters are usually more expensive than the analog ones. But even so, make sure to check the rest of the feature before investing in a pricey product because more money doesn’t always mean a better quality.
5. Weight and dimensions of the product
Think about how often are you going to use your multimeter. If you are just planning to use it around the house and not carry it with you, you can probably settle for one that is heavier and focus on more important features. But if you are a technician or an engineer and you consider taking your tool with you in many places, try to choose a pocket multimeter. They come in light weights and small dimensions so you will not see carrying it around as a struggle.

Types of Multimeters
As mentioned, multimeters can be analog ones or digital ones. And there are significant differences between these types of multimeters that you need to be aware of before purchasing one or another.
Digital multimeters:
These multimeters took the place of needle-based meters that were very popular a few years ago. They are used by professionals because they are thought to be more accurate in their measurements. Digital multimeters are also a lot more reliable and have an increased level of impedance. The main advantage of digital multimeters is that they can combine more features in one product. This allows technicians to test resistance, voltage and current by using a single digital multimeter which is very convenient. Most digital multimeters come with different features such as a display, keys to select different functions, a dial switch as well as input jacks. They also have test leads attached that go into the object that needs to be tested.
Analog multimeters:
Even if the digital multimeters are slowly taking over the market, there are still many people who prefer the analog ones and for good reasons. One of the advantages of an analog multimeter is that they show the result faster than the digital ones. They are also more resistant than the digital ones so you won’t have to replace your device as much. Unlike the digital multimeters, the analog ones use a needle that swings over the scale in order to show the result. Because they use a needle and a coil instead of a display, these multimeters also tend to have an increased sensitivity to vibrations.
Analog vs digital multimeter pros and cons, comparisons
It might be hard to decide which type of multimeter is better for you but keep in mind that ultimately, only you can make this call. These devices are used in the same purpose but they work in different ways and that comes with many advantages and disadvantages for both types. So, let’s look at each type of multimeters and see why you should consider using them as well as why you shouldn’t.
Analog multimeters
Pros:
- they tend to come at a more budget friendly price
- they last longer than the digital multimeters
- they can measure voltage, current, resistance, frequency and signal power
- analog multimeters are more accurate when testing a diode
Cons:
- These multimeters are harder to use by beginners because the reading is done by a needle calibration and not a display
- They can exhibit a lower resistance
- they are highly sensitive to vibrations and shock
Digital multimeters
Pros:
- they can measure voltage, current, resistance, frequency and signal power
- easy to use and read by everyone
- The measurements on non-diode testing are more accurate than the analog multimeters
- they come with an LED or LCD screen
- they are usually used for measuring voltage
- they have a higher resistance
Cons:
- digital multimeters tend to be more expensive than the analog ones
- they have a shorter lifespan
Analog or digital – which one is better?
Ultimately, the decision you make regarding which type of multimeter you will go for is up to you and your necessities. Generally speaking, the digital ones are more appreciated thanks to the variety of features they come with. They are also easier to use and have a higher level of portability. And even if they tend to be more expensive than the analog ones, buyers think the difference in price is well worth it. This doesn’t mean that you can’t find a high-quality analog multimeter. You just have to know what you are looking for when you are shopping for one. Hopefully, this guide answered all your questions and made your decision easier!
