Buyers’ Guide


Now that we are familiar with the best multimeter available in the market right now, let’s take a look at what things you  should consider when purchasing one. 


This feature is something that is totally dependent on your needs. If you are looking to save costs and get a budget-friendly product, then you should go for a multimeter that does not have the top of the line features. We would recommend that you look for a product that gives you all the basic features as well as some advanced ones because that will help you be more versatile and have a professional approach in your projects. There are many multimeters that have great features and are not too costly. It is worth it to invest in those products. There are some multimeters that are over $1000 whereas there are some that are even below $100. The price is something that you have to set a limit to and get the product within that price range. 


There are many different multimeters available in the market. Some of those have tons of features which will increase the price whereas some have less amount of features which will save you costs. You should consider your needs as well as the requirements of your projects. If you need a sturdy and good-looking product, then you should search for one accordingly. If you do not want a multimeter that has a LED backlight for low lit areas, you should get one that does not have this feature. This will not only save you additional costs, but you will also get a product that is best suited for you. Make sure that you keep all of your requirements in mind when searching for a multimeter. You should also look for digital multimeters because they allow you to take automatic readings. If you do not do a little research on the digital or analog multimeters, you will have a tough time buying the right product for yourself. If you are going for a digital multimeter, then you should look for a product that gives you the option to auto-range readings, read AC/DC currents and allows you to remove the data storage. 


The quality of any product is an important aspect to consider when buying it. Normally, multimeters are durable and have a sturdy design. However, there are many exceptions to this. We suggest that you take your time and look for a product that has a protective casing around it so that in case you drop it, the product does not break. At the same time, many multimeters are slow to read certain voltage which can mean that you are losing efficiency. If you search for a multimeter that has good quality, you will be guaranteed to get a good product. 


Warranty is the first thing that you should take into consideration. Many multimeters come with a warranty which can be extremely beneficial for you. This will not only save you additional costs, you can also refund or replace the product in case it does not work as intended. If the product has a warranty it will normally mean that the price will also be increased. This is not always the case because if you take your time and do a little research on various multimeters, you can find one that has a warranty and that is not expensive.  


The brand of any product is something that you should keep in mind before going out to purchase it. If you like a certain brand, then sticking to that brand is the best course of action for you. There are many brands of multimeters that offer great features, ensure good quality and even offer you a warranty all while being affordable. Brands such as the Fluke or Fieldpiece are an example of great brands which will always give you a good product. Purchasing a multimeter from a known brand will mean that you are guaranteed to get a product that will have a long life cycle and good features. There is a reason that some brands have such a strong reputation. We advise that you consider getting a multimeter from a known brand rather than an unknown one. You can also read the reviews of customers on Amazon which will give you a better idea when choosing the right brand.

Can I measure a large current with the multimeter?

You can measure large current but not with a regular multimeter. If you have a normal one, then you should consider getting a clamp meter to measure large currents. This is because of the fact that normal multimeters do not have the range to measure large currents and will overheat.

Which multimeter is better, digital or analog?

The digital multimeters are more commonly used these days due to their additional features. They will give you an automatic reading and you will have an easier time as compared to the analog one. The majority of professionals prefer the digital multimeter over the analog. 

How many readings can be saved in a multimeter?

This is dependent on the brand of the multimeter that you have. Some brands can save a lot more reading whereas others will not save that many. Generally, you can save around 400 minimum or maximum readings in the multimeter. 

What is the difference between peak modes on a multimeter?

The peak nodes are the positive and negative peak voltages of the multimeter. Whereas, the minimum and the maximum mode is the lowest and highest reading of the multimeter. The peak modes work when the peak is equal to 250 microseconds. 

Can I use my industrial grade multimeter for home use?

Yes, you can absolutely use the industrial grade multimeter inside your home. These devices are usually heavy-duty and can read more voltage than the home use multimeters. They are more durable and sturdier. 

What is a HVAC multimeter?

An HVAC multimeter is a device that is used to measure the electrical voltage. It is basically electronic test equipment which is a must-have for any person that is working with electronics. You can use the multimeter to work on the HVAC systems more conveniently.

UEI multimeters are usually good quality products that offer many great features. Not only are they reliable, but they also ensure accuracy. These multimeters are affordable and are a great value for your money. However, they are not the best when it comes to HVAC systems. 

What is the meaning of true RMS?

The True Root Mean Square (TRMS) is more accurate when you are measuring the AC current. This is why professionals use TRMS multimeters when they want to measure or work with AC current. This makes your work simpler and convenient.
