If you are an electrician, or you like DIY-projects and electronics, it is highly possible that from time to time you need to test various devices. To test an electronic device, you are going to need a digital multimeter. What is a digital multimeter? This is a small and handy device, which measures several electric properties such as electrical voltage, amperage, resistance etc. You might have heard the name “a volt-ohm meter” instead of digital multimeter (DMM). Digital multimeters are widely available on the internet, so not only professionals can use them. Depending on your needs, the price might be different. More expensive DMMs offer more functions, but if you are not a pro, you probably don’t need more advanced functions. The most basic functions that a trustworthy multimeter should have are measuring voltage, amperage, and resistance. However, some digital multimeter can also measure decibels, capacity, conductance, frequency, temperature in Celsius and Fahrenheit, duty cycles, and more. If you have never used such a tool, you may wonder how to use a digital multimeter. First of all – it isn’t complicated at all, although you need to know a few things before. Usually, there are three ports on a multimeter – red and black ones. The black one is a “common” port, and the red ones lead to specific functions. If you chose the port you want to use, and you plugged in the leads, you can now turn the knob and select the function you need to use, e.g. DC/AC voltage. Then you use the metal needles ends to read out the results. Keep in mind that it is forbidden to touch the metal ends while you are doing an energized test because you can get an electrical shock. This simple device gives you multiple advantages of use. You can use it wherever you want because the size of such a device is compact. Besides that, you can, of course, test a lot of electrical devices at home and take care of your and your family’s safety. If you are interested in buying a digital multimeter, you can read our ranking below with the 5 best multimeters that you can order online.
The 5 best multimeters
5. AstroAI M4KOR Digital Multimeter
If you want to buy a robust digital multimeter and don’t pay a lot, this is a good example for you. AstroAI M4KOR is really comfortable to use because of the silicone cover, which not only protects the device from damage or fall, but you can also hold it stable in your hand. This multimeter offers you all functions that you need to test your electronic devices at home. You can measure AC/DC voltage to 600V, resistance to 40 MΩ, current to 10A, and capacitance. This multimeter needs two AAA batteries to work. The big display is comfortable for you to read out the measurements. There are two red ports and one common black port. This device has one important advantage, namely the price. It doesn’t cost much, and it delivers all basic functions that you can use.
4. KAIWEETS H12A Digital Multimeter
This is a basic and quite cheap digital multimeter that you can use on a daily basis. The small size and useful case allows you to transport it if needed. Even though the price of this digital multimeter is not the highest, it offers a lot of useful functions. You can measure AC/DC voltage, DC current resistance, continuity. There is also a diode measurement. The accuracy of each measurement is wide: AC voltage from 20 V to 600V, DC voltage from 200 mV to 600 V, DC Current from 20 mA to 20A, and resistance from 200 Ω to 20 MΩ. A helpful function is the backlight, which helps with viewing the results in the dark. You can also use a support stand to put the device on any flat surface.
3. KAIWEETS HT118A Digital Multimeter
The most important thing for any electrician is the accuracy of the measurements. This digital multimeter has plenty of positive reviews because of its high quality, great accuracy and good quality leads. Besides that, there are four ports – three of them are red, and one is black. The more ports, the more options you have. The silicone case protects the device from unpredicted falls and the Anti-Burn system avoids serious accidents while doing measurements. The backlight increases the visibility of the screen, so you can read out the results in the dark. Besides, the usual functions such as AC/DC voltage etc., this device can also test temperature, capacitance, frequency, duty cycle, wire on-off, diodes and continuity. This is a great digital multimeter for a professional electrician.
2. AstroAI AM33D Digital Multimeter
For those who want to buy a basic, non-expensive, but handy and useful digital multimeter to use at home, AstroAI AM33D is a good choice. You are probably going to measure the AC/DC voltage (in this case up to 500V). You can, of course, measure the DC current, resistance, continuity, and diode. The simple design with the backlight display and low battery indicator make it intuitive to use. It does its job very well because the measurements are accurate. Great value and very reasonable price make this device one of the best rated on Amazon.
1. AstroAI DM6000AR Digital Multimeter
The best digital multimeter on this list is AstroAI DM6000AR because of its multiple advantages. There are a lot of functions that this device offers. First of all you can measure the AC/DC voltage, AC/DC current, resistance, and continuity. If you need more specific functions, it is also possible to test diode, capacitance, frequency, and temperature. The maximum DC voltage that can be tested is 1000V, and max. AC Voltage is 600V. There are four ports, which give you more opportunities to test various devices. Double protection and anti-burn take care of your safety at work. The robust case protects the device from breaking.
