10 Best Auto Multimeters 2025 in the United States

The Klein Tools ET270 is a solid choice for those needing a versatile and reliable auto-ranging multimeter, especially for household and light professional electrical tasks. It measures AC/DC voltage up to 600V and resistance up to 40MΩ, which covers most common electrical testing needs. Its accuracy is good enough for everyday use, though it’s not aimed at high-precision lab work. The bright backlit LCD display makes it easy to read measurements even in dim conditions, a helpful feature for work in tight or poorly lit spaces. Safety is well covered with CAT III/CAT IV rated test leads, which means it’s designed to handle demanding electrical environments safely.

The included GFCI receptacle tester and trip time display add value by helping users quickly diagnose wiring problems and check GFCI devices. Extra features like battery testing and a find mode for circuit breakers enhance its usefulness beyond standard measurements. The tool’s durability is reinforced by thoughtful design elements such as test lead holders, a kickstand, and compatibility with magnetic hangers, making hands-free use convenient. At under 9 ounces, it’s lightweight and portable, fitting easily into its included carrying case.

One downside is that the power source relies on AAA batteries, which might need regular replacement with frequent use. Also, while it covers many functions, users needing advanced or very high-accuracy measurements might find it somewhat limited. This makes the Klein ET270 user-friendly and packed with practical features, making it a dependable multimeter for electricians, DIYers, and anyone who frequently tests home wiring or appliances.

The Fluke 115 Digital Multimeter is a versatile tool that caters well to field technicians and general use. Its True-rms capability ensures accurate readings for both AC and DC voltage up to 600V and current up to 10A, which is quite reliable for various electrical measurements. The multimeter also measures resistance, continuity, frequency, and capacitance, making it a comprehensive tool for different tasks.

Recording signal fluctuations is simplified with its Min/Max/Average function, which can be very useful in diagnosing issues over time. Users will appreciate the large white LED backlight, which enables operation in dimly lit environments, adding to the convenience of use. At 1.4 pounds, it is lightweight and portable, making it suitable for on-the-go professionals. The included battery, holster, and test leads add value to the package right out of the box.

Safety is a priority with a CAT III 600V safety rating, ensuring protection against electrical hazards. However, the 600V limit might be restrictive for some high-voltage industrial applications, and the lack of advanced connectivity features like Bluetooth or USB might be a downside for those looking for more modern integrations. Nonetheless, for its ease of use, comprehensive feature set, and solid safety ratings, the Fluke 115 is a strong choice for technicians needing a dependable and accurate multimeter for everyday tasks.

The Fluke 117 Digital Multimeter is a highly regarded tool for measuring various electrical parameters such as resistance, continuity, frequency, and capacitance. One of its standout features is the VoltAlert technology, which allows for non-contact voltage detection, making it safer and more convenient to use. It also has an AutoVolt function that automatically selects AC or DC voltage, simplifying the process for the user.

The large white LED backlight ensures that the display is easy to read, even in poorly lit conditions. Its True RMS capability means it provides accurate measurements even on non-linear loads, which is beneficial for more complex electrical systems. The low input impedance feature helps to prevent false readings caused by ghost voltage, enhancing its reliability.

Additionally, its operating temperature range and battery life of around 400 hours (without backlight) make it a durable choice for prolonged use in various environments. The product is battery-powered and comes with the necessary batteries included, so it’s ready to use right out of the box. However, with a weight of 550 grams, it may be slightly heavier to handle for some users. In terms of safety, the Fluke 117 meets IEC standards, offering peace of mind during use. On the downside, it is relatively more expensive than other multimeters in the market. Despite being on the pricier side, its high customer rating (4.8 out of 5 stars) reflects user satisfaction. The Fluke 117 is well-suited for professionals and enthusiasts who need a reliable, accurate, and feature-rich multimeter for various electrical tasks.
