5 Best Klein Multimeters 2025 in the United States

The Klein Tools MM325 Multimeter offers versatile functionality, measuring AC/DC voltage up to 600V, 10A DC current, and 2MΩ resistance. It also includes features like continuity testing, diode testing, and battery testing, making it suitable for various applications. One standout feature is its lead-alert protection, where LEDs illuminate to indicate proper test lead placement, enhancing both accuracy and safety.

The backlit LCD display ensures clear readings even in low-light conditions, which is handy for use in dimly lit areas. Additionally, the multimeter is designed with convenience in mind, featuring test lead holders, a kickstand, and compatibility with optional magnetic hangers for hands-free operation.

Durability is another strength, as it is built to withstand a 6.6-foot drop, making it robust for use in residential, business, and light-industrial environments. It also comes with necessary accessories like test leads with CAT III/CAT IV safety caps and instructions, plus batteries, which provides a complete package right out of the box. However, it is a manual-ranging multimeter, which might not be as user-friendly as auto-ranging models, requiring more input from the user to select the correct range for measurements. Its reliability and comprehensive feature set make it a solid choice for those needing a durable and versatile multimeter for various electrical testing needs.

The Klein Tools 69149P Electrical Test Kit is a versatile and complete package suitable for a range of electrical testing needs. This kit includes a digital multimeter, a non-contact voltage tester, and an electrical outlet tester, making it a solid choice for both professionals and DIY enthusiasts. The multimeter can measure up to 600V AC/DC voltage, 10A DC current, and 2MOhms resistance, which covers most common electrical tasks. It also features continuity testing with visual and audible indicators, which can help in determining circuit status quickly and efficiently.

The non-contact voltage tester (NCVT1P) provides a bright LED and audible tone to indicate voltage presence in the range of 50 to 1000 VAC, enhancing safety during testing. The electrical outlet tester helps in identifying wiring configurations and common faults, although it may not detect more complex issues. The test kit offers reliable performance with necessary accessories included, such as test leads and batteries, ready for use straight out of the box.

One of the main drawbacks is the multimeter's lack of auto-ranging, requiring manual range adjustment which might not be as convenient for some users. Additionally, while the build quality is solid, it’s lightweight at under a pound, which might not give the impression of durability over extended heavy-duty use. Nevertheless, the safety ratings and the comprehensive features make it a practical and effective choice for various electrical assessments.

The Klein Tools CL390 AC/DC Digital Clamp Meter is a versatile and feature-rich multimeter suitable for a variety of electrical testing needs. It excels in measurement functions with capabilities to measure AC/DC current, voltage, resistance, continuity, frequency/duty cycle, DC microamps, diode test, capacitance, and temperature. This wide range of functions makes it a valuable tool for both professional electricians and DIY enthusiasts. The inclusion of non-contact voltage testing (NCVT) integrated into the clamp jaw adds convenience, allowing for safer and easier testing without direct contact with wires.

The high-visibility reverse-contrast LCD display ensures clear viewability in different lighting conditions, which is a significant advantage when working in dimly lit areas. Additionally, the auto-ranging feature and True Root Mean Squared (TRMS) technology ensure accurate measurements, which is crucial for reliable diagnostics. The clamp meter also includes several user-friendly features such as a test lead holder, optional magnetic hanger for hands-free operation, Max/Min, Rel/Zero, and Data Hold capability.

Furthermore, it has an auto-power off function to conserve battery life, which is practical for long-term use. On the safety front, the included test leads with CAT III/CAT IV safety caps enhance user protection, making it a suitable choice for working on high-energy circuits. Despite its many strengths, the Klein Tools CL390 is battery-powered, which might require regular battery changes, and at 8.32 ounces, it is fairly lightweight, which may raise concerns about durability in heavy-duty environments. Nevertheless, its comprehensive feature set and ease of use make it an excellent tool for a wide range of electrical testing applications.
