10 Best Multimeters 2025 in the United States

The AstroAI Digital Multimeter is a versatile tool that can accurately measure AC/DC voltage, DC current, resistance, and diodes, making it useful for a wide range of electrical troubleshooting tasks. It is particularly suitable for household outlets, fuses, batteries, and automotive circuits.

One of its significant strengths is its ability to test various battery voltages (1.5V, 9V, and 12V) and automatically display the battery status, which is very handy for those who frequently deal with batteries. The multimeter is designed with safety in mind, featuring double fuses to prevent overloading and a silicone cover to protect against drops and electric shocks.

Additionally, it has useful features like a data hold function, auto shutoff, a continuity buzzer, and an LCD backlit screen for easy use in dim light conditions. The inclusion of batteries and test leads in the package is a nice touch, adding to its convenience. However, it is worth noting that this multimeter cannot test AC current, which could be a limitation for some users. Also, beginners should ensure they set the multimeter to the correct setting before testing to avoid incorrect readings or potential damage. Despite these drawbacks, this multimeter is a solid choice for DIY enthusiasts and hobbyists looking to handle household or automotive electrical issues safely and accurately.

The AstroAI Digital Clamp Meter Multimeter is a versatile tool designed to measure various electrical parameters, making it suitable for both industrial and household use. It accurately measures AC current (not DC current), AC/DC voltage, resistance, capacitance, diode continuity, and performs live wire tests. One of the standout features is its non-contact voltage testing capability, which includes both sound and light alarms, enhancing user safety and convenience.

The large jaw opening allows for easy measurement of AC current without breaking the circuit, and the compact design ensures ease of use in tight spaces. Additional thoughtful features such as data hold, max/min readings, auto shut-off, low battery indicator, and a built-in flashlight add to its practicality. The device is powered by two AAA batteries, which are included in the package.

Safety-wise, it meets environmental pollution degree 2 and overvoltage category III 600V standards. However, it’s important to note that this meter does not measure DC current, which might limit its use for some users needing that specific function. This clamp meter is best suited for general-purpose electrical troubleshooting and maintenance tasks.

The Klein Tools MM325 Multimeter is a versatile digital device suitable for various electrical testing tasks. It measures AC/DC voltage up to 600V, 10A DC current, and resistance up to 2MΩ, making it adequate for most residential and light-industrial applications. The multimeter includes continuity, diode, and battery tests, enhancing its utility for everyday use. Notably, the lead-alert protection feature, with LEDs indicating test lead placement, supports safety and accuracy in measurements.

The backlit LCD display improves readability in low-light environments, a practical aspect for users working in dim settings. Additional convenience is offered by test lead holders, a kickstand, and compatibility with a magnetic hanger for hands-free operation, which can be particularly beneficial for prolonged tasks or complex setups.

In terms of build quality, the MM325 is designed to withstand a 6.6-foot drop, indicating robust durability. This feature, along with CAT III/CAT IV safety caps on the test leads, underscores its suitability for controlled environments such as homes and businesses. Given its features and durability, the Klein Tools MM325 is well-suited for DIY enthusiasts and professionals working in standard environments who require a reliable, basic multimeter with clear readings and solid safety features.
