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

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 28IIEX/ETL Intrinsically Safe True-RMS Digital Multimeter stands out for its robust and durable build, making it suitable for use in hazardous environments such as oil refineries, mining operations, and pharmaceutical plants. Its key advantage is the True RMS functionality, which ensures accurate readings for both linear and non-linear loads - a critical feature for automotive use where you may encounter varying types of electrical signals.

It offers a wide range of measurements including voltage, current, conductance, duty cycle, capacitance, frequency, and temperature, plus resistance, continuity, and diode tests, which covers most automotive diagnostic needs. The auto-ranging feature simplifies the measurement process by automatically selecting the appropriate measurement range, enhancing user convenience. The low-pass filter is another plus, as it prevents interference from unwanted voltages when measuring AC voltage and frequency, ensuring accurate readings on advanced automotive systems like inverters and variable-frequency motor drives. The device is IP67 rated, indicating it is dustproof and waterproof, which adds to its durability in tough working conditions.

There are a few drawbacks. Despite its extensive features, it is on the heavier side at nearly 3 pounds, which might be cumbersome for prolonged use. The LCD display, while functional, may not offer the same clarity as more advanced displays, especially in low-light conditions. Additionally, the multimeter requires 4 AA batteries, which are not included in the package, potentially adding to the cost and inconvenience. This multimeter is a reliable and feature-rich tool, particularly suited for professional environments where safety and accuracy are paramount. For automotive technicians working in less hazardous settings, its extensive safety features might be more than necessary, potentially making it a more expensive option than required.

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.
