Best Multimeters You Can Buy


A digital multimeter (DMM) is a necessary tool for every electronic enthusiast’s toolbox. For a relatively cheap tool, multimeters actually offer a lot of functions. You can use it to diagnose circuits, read pre-existing electronic design, and test batteries. To help you pick the best digital multimeter out there, we present to you our top picks.

Our Pick: AstroAI Digital Multimeter

This AstroAI Digital Multimeter with Ohm Volt Amp and Diode Voltage Tester Meter helps you troubleshoot different forms of electrical problems safely and accurately. You can use this multimeter for house outlets, fuses, general-purpose batteries, wiring, car battery, and more. It can measure/test amp, current, continuity, DC, diode, voltage, resistance, and other units of measurement. With a fast sampling speed of 2 times per second, this device really provides premium quality feats for a reasonable price.

This DMM has a data hold function that allows you to freeze the displayed data on the digital display. It is also very user-friendly because of its simplified functions, large digital display, backlit LCD, and a built-in kickstand for hands-free use.

It is also covered by a protective rubber case for drop protection. Mechanically, it offers overload protection on all ranges.

Runner Up: Etekcity Digital Multimeter, MSR-C600

One of Etekcity Digital Multimeter MSR-C600’s best feature is its auto-ranging assistance that measures AC currents, AC/DC voltage, resistance, and other forms of measurement. It also has a data hold feature and an easy-to-read large LCD for ease of use. Another great feature is its max value button for quicker operation. It automatically enters sleep mode after 15 minutes of inactivity because of its auto-off feature. Etekcity also offers 1-year warranty and lifetime support for this DMM product.

Also Great: Fluke 117 Electricians True RMS Multimeter

The Fluke 117 Electricians True RMS Multimeter is a fancy option if you have extra money to spare. After all, this is the Mercedes Benz of DMMs. It looks simple but it is expensive, versatile, and highly functional. Its low input impedance eliminates false reading triggered by to ghost voltage. While its VoltAlert technology for non-contact volt detection enables you to finish the job faster than ever.

The device offers minimum/maximum/average readings, measuring frequency and capacitance. Given its wide-array of functions, it is still easy to use. This gives you more time to do other work. All of its features will give competitors a run for their money. This product shines under more demanding work settings such as commercial buildings, hotels, hospitals, and schools. But as mentioned, one of its downsides is its price. It is a lot more expensive than other brands, but it will surely give you your money’s worth.

If you want to save a little bit of money but still interested to buy a good quality DMM, try checking the Etekcity Digital Multimeter MSR-R500. This one can perform what top manual ranging DMMs can do. It has a sampling speed of 3 times per second. It can perform a diode test and continuity test. It also accurately measures resistance, AC/DC voltage, and more. It is best when used for automotive and household electrical woes. One of its downsides, however, is its inability to test AC currents.

Its built-in support enables hands-free use. Its whole package includes 1 Etekcity MSR-R500 DMM, a pair of test leads, and a GP supercell battery.

What Makes a Good DMM?

  • Backlit LCD

    Not all DMMs are equipped with backlit LCD. Though it sounds fancy, backlit LCD really allows you to work even during the dark. This is quite handy in dimly lighted work stations.

  • Good knob

    Sharp clicks could be a good indicator of a well-built knob. It gives a sense of durability and precision that DMMs need.

  • Auto-off feature

    This should be a must in the context of modern electronics development. An auto-off feature helps you save precious energy and the run life of your device.

  • Auto-ranging

    Some of the most expensive multimeters do have an auto-ranging function. This means that they automatically adjust their auto-range attempt to find the correct current, resistance, and voltage.

How to Change DMM Fuse?

One of the most common problems that DMM owners encounter is a blown fuse. If you experience a blown fuse while using your DMM, you would want to replace it the soonest. This is actually easy if you just follow these steps.

  1. Prepare your mini screwdriver. Remove all the screws that hold the case (make sure that you place each screw in a place where they won’t easily get lost). You also need to remove the battery and battery plate from your device.
  2. Look for the screws behind your battery plate and remove them. This would give you the freedom to fully check the inside of your DMM. After removing these screws, you just need to carefully lift the case that protects the inside-part of the DMM.
  3. After finishing that part, you now need to search for the fuse. It is a cylindrical-shape piece that is usually placed at the upper part of the device. You can remove it with a little bit of pressure. Just be careful in this process to avoid any unwanted damages to your DMM.
  4. As it pops out, you can now replace it with a new fuse. But before that, make sure that your replacement is compatible with your DMM (a 200mA should be replaced with 200mA). You need to have the correct fuse type to make this work. Check your manual to see the specs of your fuse.
  5. After doing all that, you can now reassemble the device together. Re-examine if everything is working fine.


In this list, we have AstroAI Digital Multimeter as our top pick. It is an all-around DMM that is energy-efficient and easy to use. Its price is very reasonable considering all of its functions. If you are looking for DMM for household and car electronic use, this item is a good place to start!
