6 Best Uei Multimeters 2025 in the United States

The UEi DL389B Digital True RMS Clamp Meter is a versatile tool suitable for industrial and HVAC applications. One of its standout features is its True RMS capability, ensuring accurate measurements regardless of the load type. It covers a broad range of measurements, including AC/DC volts, AC amps, microamps, temperature, frequency, resistance, and more, making it a comprehensive tool for various tasks.

The auto-ranging function simplifies usage by automatically selecting the appropriate measurement range. The dual display is backlit, providing clear readability in different lighting conditions, and the magnetic mount allows for hands-free operation, enhancing convenience during use. Additionally, the built-in work light is useful for working in dim environments, and the included test leads, temperature probe, and zippered pouch add to its practicality and portability.

In terms of safety, the DL389B is rated CAT IV 300V and CAT III 600V, offering increased protection during measurements. However, on the downside, some users might find the weight and size slightly cumbersome for prolonged use, and being powered by AAA batteries means you'll need to keep spares on hand for uninterrupted operation. Nevertheless, its robust design and comprehensive feature set make it an excellent choice for professionals in industrial settings.

The UEi DL369 Digital Clamp Meter is a versatile tool designed for various electrical testing needs, making it highly suitable for HVAC professionals. One of its standout features is the dual display, which boasts a 4000 count resolution, ensuring clear and precise readings. Additionally, it offers a wide range of measurements, including AC current up to 400A, AC/DC voltage, microamps, capacitance up to 4000µF, resistance up to 40MΩ, and more. This range reduces the necessity of carrying multiple tools, boosting convenience on the job site.

The inclusion of non-contact voltage (NCV) detection enhances safety by allowing users to identify live wires without direct contact. Auto-ranging and Min/Max functions further add to its usability, making it easier to handle various measurement tasks. Durability is also a strong point, with the device built from robust ABS plastic and backed by a 3-year limited warranty, ensuring peace of mind for long-term use.

However, at 0.65 ounces, some might find it lighter than expected, which could affect how sturdy it feels in hand. Lastly, the auto power-off feature helps conserve battery life, though some users might find it inconvenient if it activates too soon. The UEi DL369 offers a comprehensive set of features at an affordable price, making it a valuable tool for anyone in the electrical or HVAC field.

The UEi DL379B Digital Clamp Meter is a versatile tool designed primarily for industrial use, offering a wide range of functionalities. One of its key strengths is its accuracy and range, as it can measure AC and DC volts, AC amps, temperature, capacitance, frequency, diodes, duty cycle, continuity, and resistance up to 40MΩ. This makes it highly suitable for HVAC technicians and other electrical professionals. The auto-ranging feature simplifies the measurement process by automatically selecting the appropriate measurement range, enhancing user convenience and accuracy.

The dual backlit display is a significant advantage, providing clear visibility even in dimly lit environments, and the magnetic mount allows for hands-free operation, which can be a real time-saver. Additionally, the built-in work light is a thoughtful touch for those working in dark spaces. In terms of safety, the DL379B stands out with its CAT IV 300V and CAT III 600V safety ratings, along with non-contact voltage detection to identify live wires without contact. The input jack locks prevent accidental damage to the meter, adding an extra layer of protection.

Durability is another plus, with the meter being commercial grade and coming with a 3-year limited warranty. However, its lightweight design at just 0.75 ounces might make it feel less robust than other models, and users looking for a more substantial grip might find this a bit lacking. Also, while it includes useful components like test leads, a K-Type temperature probe, and batteries, the zippered pouch might not provide the highest level of protection for the tools during transport. This clamp meter is an excellent choice for those needing a comprehensive, feature-rich tool for professional electrical work.
