6 Best Fluke Multimeter For Automotive Use 2025 in the United States

The Fluke 117 Digital Multimeter is a solid choice for automotive use, particularly due to its accurate measurements and user-friendly features. One of its standout strengths is the True RMS functionality, which ensures accurate readings on non-linear loads, a common scenario in automotive applications. The AutoVolt feature for automatic AC/DC voltage selection adds convenience, making it easier for users to switch between measurements without manual adjustments. VoltAlert technology for non-contact voltage detection is a great safety feature, allowing users to identify voltage without direct contact.

The large LED backlight facilitates working in low-light conditions, which is often necessary in automotive environments. With a measurement accuracy of +/-0.5%, the Fluke 117 provides reliable data for diagnosing electrical issues.

There are a few potential drawbacks to consider. While the multimeter is quite durable, its plastic construction may not withstand extreme conditions as well as some metal-bodied models. The battery life is impressive at around 400 hours, but it requires 2 AA batteries, which need to be replaced periodically. Additionally, while the multimeter is versatile, it may have more features than a casual user requires, making it potentially overwhelming for beginners.

The Fluke 117 is an excellent tool for professionals and enthusiasts in the automotive field who need reliable, accurate readings. Its combination of accuracy, safety features, and convenience make it a worthwhile investment, although those new to using multimeters might need some time to get accustomed to its full range of capabilities.

The Fluke 1587 FC 2-in-1 Insulation Multimeter is designed with automotive use in mind, making it a solid choice for professionals and hobbyists alike. One of its standout features is its auto-ranging capability, which simplifies measurements by automatically selecting the correct range. This is particularly helpful for users who may not be familiar with specific voltage levels. The device offers accurate insulation test voltages, ensuring reliable results when diagnosing electrical systems.

The multimeter is equipped with advanced testing functions like the PI and DAR tests, which help identify insulation problems quickly. Its integration with the Fluke Connect app allows for memory storage and historical tracking, reducing the chances of errors in recording results. Users will appreciate the convenience of receiving temperature-compensated measurements and being able to graph trends, making it easier to spot issues over time.

Durability is another strong point, as Fluke is known for building robust tools that can withstand the wear and tear of an automotive environment. The inclusion of a low-pass filter for motor drive measurements is a valuable feature for those working with variable frequency drives (VFDs). At a weight of 300 grams, it may feel a bit heavier compared to other models, which could be a concern for prolonged use. Some users might find the reliance on batteries a drawback, especially when working in busy environments. Additionally, the price point may be on the higher side for casual users who don’t need advanced features.

The Fluke 87V Max True-RMS Digital Multimeter is a robust tool specifically designed for automotive use. One of its key strengths is its durability; it can withstand drops from up to 4 meters and has a waterproof and dustproof IP67 rating. This makes it suitable for challenging environments, which is essential for automotive technicians who often work in less than ideal conditions. The meter's CAT III 1000 V and CAT IV 600 V ratings add a layer of safety when measuring high voltages, which is crucial in automotive applications.

In terms of functionality, the auto-ranging feature simplifies the measurement process, allowing users to quickly get accurate readings without the hassle of adjusting ranges manually. The True-RMS capability ensures reliable measurements for both AC and DC voltages, a significant advantage for diagnosing complex automotive electrical issues.

There are a few drawbacks to consider. While the multimeter is well-equipped for electrical measurements, it may lack some additional automotive-specific features that some users may find beneficial. Moreover, the price point is on the higher side, which may not appeal to occasional DIY users or those with limited budgets. The display is easy to read, but in bright sunlight, visibility might be a concern for some users. Lastly, while the included MC4 test leads are great for specific applications, automotive professionals should ensure they have all necessary accessories for various tasks.
