However, the weight at 0.7 kilograms might be slightly on the heavier side for prolonged handheld use.

This kit runs on alkaline batteries, which are readily available but may require frequent replacements depending on usage. While it's feature-rich, it may have a steeper learning curve for beginners due to the wide range of functions and settings. This multimeter is best suited for automotive professionals or serious hobbyists who need a reliable, durable, and highly accurate tool for their diagnostics and repair tasks.

The Fluke 88V Deluxe Automotive Multimeter is specifically designed for troubleshooting problems in both conventional and hybrid vehicles, making it a versatile tool for automotive professionals. It offers a comprehensive measurement range, including AC/DC voltage, AC/DC current, resistance, capacitance, frequency, and temperature, which covers most diagnostic needs. The manual and auto-ranging modes provide flexibility, allowing users to choose their preferred method of measurement.

The built-in thermometer is a convenient feature that eliminates the need for a separate temperature measuring device. Additionally, it can perform millisecond pulse width measurements for fuel injectors, which is essential for diagnosing modern vehicle issues. The Fluke 88V is robust, with a safety rating for Category III up to 1000V and Category IV up to 600V, and it can withstand hazardous 8,000-volt spikes, ensuring durability and safety in various environments.

It also features a Peak Min/Max recording function to capture quick transients, up to 250 microseconds. However, at 3 pounds, it is relatively heavy, which might be cumbersome for prolonged use. The 9V battery power source is standard, but users should be prepared for regular battery replacements. The Fluke 88V stands out for its accuracy, durability, and range of features, making it an excellent choice for automotive diagnostics, though its weight and battery dependency might be minor drawbacks for some users.

The Fluke 87V MAX is a solid choice for anyone needing a reliable automotive or industrial multimeter. It offers True-RMS accuracy, which means it can measure complex electrical signals more precisely than basic meters—this is especially helpful when working with automotive electronics. The device supports all the essential measurement functions of the original Fluke 87V, with upgraded test leads included. Its display is clear and easy to read and is generally known for good visibility in various lighting conditions.

One of the standout features is its rugged build: it’s waterproof and dustproof with an IP67 rating, meaning it can handle wet and dirty environments without trouble. It also survives drops from up to 13 feet, making it tough enough for fieldwork. The meter is safety-rated for high voltage environments (CAT III 1000 V and CAT IV 600 V), which adds peace of mind when working around heavy electrical systems. With up to 800 hours of battery life, it’s built for long use without frequent battery changes. Auto-ranging is included, so you don’t have to manually set the measurement range, which simplifies use and reduces errors. The built-in thermometer is a helpful extra for diagnosing automotive or electrical issues that involve temperature.

On the downside, the meter weighs around 700 grams, which might feel a bit heavy for some users during extended handheld use, and it requires three AA batteries, which aren’t rechargeable, potentially adding ongoing cost and inconvenience. While it’s priced higher than basic models, its durability and accuracy make it worth the investment for professionals or serious hobbyists. The Fluke 87V MAX is a durable, accurate, and feature-rich multimeter that suits demanding environments and users who need reliable, precise measurements in automotive or industrial settings.
