Best Automotive Multimeter — Buyers Guide, Review, and Comparison

Fluke 115

This product has a pretty impressive list of features and functions. You can test capacitance, continuity, frequency, and efficiency with high precision. A pair of test leads are included with the meter.

The True RMS function is what makes this multimeter worth checking out. It allows the meter to offer precise data by eliminating electrical noise in the environment. If you’re familiar with the True RMS concept, you know how useful it is, especially with older electrical devices and gadgets that emit a lot of electrical noise.

The large display and a bright LED backlight offer crystal-clear readings. One thing worth mentioning is that you can read the results from any angle, even from 45 degrees, while it’s not possible with many other models. The design is neat, sturdy, and durable, which is a characteristic of almost every product made by Fluke. As far as precision and accuracy go, the Fluke 115 is near the top.

It’s great for field interventions because of its size. It weighs only 1.3 pounds, and it’s small size means it will easily fit in your pocket. For the best experience, the Fluke 115 also offers auto ranging to facilitate the use further. You don’t have to set the values manually — the unit will do that for you, which saves a lot of time and effort. 

The meter is CAT III 600-volt safety rated — even beginners can use it without exposing themselves to risks. If you’re looking for a compact and lightweight tool for quick jobs of measuring and testing various current-related values, make sure to check the Fluke 115 out. It has everything you need in a multimeter and, most importantly, the price is great.

Etekcity MSR-A1000 Digital Multimeter

The multimeter is large enough to include all the necessary options, but small enough to be easy to transport and use. The MSR-A1000 includes features that make it simple to use, such as a large LCD screen display. It includes a hook to clip the device out of the way and a rotary dial that is easy to use.

The Etekcity MSR-A1000 was designed with safety in mind. An automatic shutoff feature preserves the batteries. There is a non-contact voltage mode, which allows you to safely test potentially hot or live wires without direct contact. This device also provides both reverse polarity protection and overload protection. The multimeter also has two ceramic tube fuses, rather than the single ceramic tube fuse that many multimeters use for protection.

Innova 3320 Auto-ranging Digital Multimeter

The first great thing about the Innova 3320 is the battery load test function. It’s used for checking whether your car battery (or any battery) is performing well. It may not sound like it’s a big deal, but if you take a moment and think about it, you’ll realize it means you don’t have to buy separate tools to diagnose your battery condition.

It also has an auto-ranging function, which will help you to save some time and effort. It selects the proper range automatically, so you don’t have to. This feature is especially useful for those among us who aren’t experts when it comes to dealing with electricity, batteries, and multimeters in general.

The large digital display is also an important feature of the Innova 3320. Many multimeters nowadays have a small, almost illegible screen, which can be a burden in certain lighting conditions, for example. The overall design is neat; it has a built-in stand and wrist wraps which guarantee a firm grip. Because of the sturdiness of this unit, it can also withstand bumps and drops.

There’s a single-setting resistance function for both DC and AC on this unit. It comes with a safety certification issued by the UL, and while this doesn’t sound too impressive, it offers contentment and peace of mind. Although some users doubt its reliability, you can rest assured that you’re going to get precise and accurate readings.

One thing that makes this company stand out is the customer support. Some manufacturers neglect their customers and provide poor after-sales support, but Innova has a team of people who are ready to answer your questions and help you with potential issues.

Inova 3340

This multimeter provides a variety of functions and is easy to use for anyone, from those who have not previously dealt with a digital multimeter before, to experts in the world of automotive repair. Should your engine be acting up, the Innova 3340’s sophisticated design will help you determine what is wrong with it. 

The temperature probe feature provides accurate temperature readings in both Fahrenheit and Celsius. The multimeter also comes with an inductive clamp, which measures the RPM (revolutions per minute) of your vehicle. 

Just about everything under your vehicle’s hood can be tested by this device, from the alternator diodes to the breaker points and wiring. Best of all, you can transport it easily. The Innova 3340 is a handheld, modestly-sized digital multimeter, and comes with its own carrying case (which can be fit easily inside your toolkit).

What’s more, the Innova 3340 works for more than just your vehicle. It can also provide great service to you around the home. For instance, its ability to act as an electric multimeter/voltage meter means that it can determine whether or not a wall socket is functioning properly.

For anyone in need of a tool that acts as both an automotive multimeter and an electric multimeter/voltage meter, look no further than the Innova 3340. The price of the Innova 3340 is reasonable as well, considering all the functions that it offers. 

Should you have any technical problems that occur while using the Innova 3340, it comes with a one-year warranty. covering repairs or replacements, if necessary.

Fluke 77-IV

The Fluke 77-IV has both manual and auto ranging options, which means you can choose either, depending on your personal preferences. The large digital display is backlit with a bright LED light, which comes in handy if you’re working in dimly-lit areas.

Whether you want to check the electronics in your car or test some batteries in your home, the Fluke 77-IV won’t let you down. It’s designed both for field work and bench repairs. 

The voltage resolution range is pretty wide — it goes from 1mV up to 1000V for AC and DC. The current range for both AC and DC is 10 amps. The capacitance and resistance ranges are also wide enough to accommodate every need and demand.

A beeper is integrated into the unit, to notify the user and indicate diode and continuity results. One of the things that stands out is the device’s accuracy. With 0.3% accuracy, it’s among the most precise ones in this category. 

Some other features differentiate this item from others, too. For example, while it’s advertised as an automotive multimeter, it can be easily used for household purposes as well.

Since it meets most of the requirements of a professional user, its affordable price is another thing worth mentioning. One would expect a higher price for a tool like this. It’s worth mentioning that the Fluke 77-IV is designed in the United States, while many others come from licensed factories on the Asian market

Etekcity MSR-C600

This unit is special because it’s a multimeter with clamps. Digital clamp meters allow you to conduct an analysis without having to cut down the wires or strip down the cord.

The auto shut down option might not seem too impressive, but it’s quite useful, especially if you have a habit of forgetting to turn your devices off after use. This feature alleviates the issue by turning the unit off after 15 minutes of inactivity. Needless to say, it prolongs the battery life as well as saving money.

The auto ranging feature is great for beginners and those who don’t want to bother with manual settings. You will also get an audible warning if you try to conduct a measurement under the wrong settings or circumstances. 

While it might not be perfect for professionals, it’s a great tool for DIY enthusiasts and people who occasionally deal with electricity and car batteries. The display and markings are easy to see and read. It also comes in a neat case that lets you keep the meter and leads together without anything getting tangled up.
