10 Best Automotive Multimeters 2025 in the United States

The Klein Tools CL120VP Electrical Voltage Test Kit is a comprehensive package designed for automotive electrical testing. It includes a clamp meter that measures AC current and features a non-contact voltage tester, making it versatile for various applications. The kit also provides test leads, a GFCI receptacle tester, and a voltage tester for both AC and DC voltages.

One of its significant strengths is the auto-ranging technology, which ensures accurate measurement by selecting the appropriate range automatically, making it user-friendly, especially for those who are not tech-savvy. The built-in flashlight is a handy feature for working in dark spaces, and the test lead holder and optional magnetic hanger offer convenience for hands-free operation. The CL120VP is well-built, with a durable design that can withstand regular use.

The inclusion of multiple testers in one kit provides great value and covers a broad range of testing needs. However, the product might be somewhat bulky, weighing 1.8 pounds, and its larger dimensions might be less convenient for some users who need a more compact tool for on-the-go testing. Additionally, users should be aware that the product is hand-powered, requiring manual effort. Those looking for a simpler, more compact solution might find it excessive for their needs.

The Fluke 15B+ Digital Multimeter is a robust tool designed for various electrical applications, making it a reliable choice for automotive and residential use. One of its standout features is the CAT III 600V safety rating, which ensures safety while working on electrical systems.

This multimeter can measure AC/DC voltage up to 1000V and current up to 10A, which makes it versatile for different tasks such as diagnosing automotive electrical issues or troubleshooting home electrical systems. Additionally, it offers measurements for resistance, continuity, diodes, and capacitance, providing all the essential functions needed for comprehensive electrical diagnostics and repairs. The auto-ranging feature adds convenience by automatically selecting the correct measurement range, simplifying the task for the user. The display is clear and easy to read, which is crucial when working in various environments.

On the downside, the weight of 460 grams might be considered a bit heavy for prolonged handheld use, and it runs on batteries, which might require frequent replacements depending on usage. The build quality is solid, typical of Fluke products, ensuring durability over time. In summary, the Fluke 15B+ Digital Multimeter is a dependable and multifunctional tool ideal for users who need a reliable and safe multimeter for both automotive and residential electrical applications.

The Klein Tools ET600 Multimeter is a robust and versatile option for automotive multimeter users. It covers a wide measurement range, including insulation resistance up to 4000MΩ and voltage measurements up to 1000V AC/DC. The auto-ranging True Root Mean Square (TRMS) technology increases the accuracy of measurements, which is crucial for precise diagnostics. The device also includes essential safety features like a high voltage icon and warning alarm, which are critical for safe operation during electrical testing.

The backlit display with additional icons like Auto-power off, High Voltage, Max/Min, and Hold make it user-friendly, even for those who might not be tech-savvy. The inclusion of a low battery indicator and easily replaceable battery and fuse ensure the device is convenient to maintain. However, the device is relatively heavy at 1.4 pounds and requires 6 AA batteries, which could be seen as a drawback for some users who might prefer a lighter, rechargeable option. Also, the dimensions (10 x 2 x 4.5 inches) make it somewhat bulky, which might not be ideal for those needing a more compact tool.

The Klein Tools ET600 offers reliability, safety, and a good range of features, making it a strong candidate for both professional electricians and dedicated DIY enthusiasts.
