10 Best Oscilloscope Multimeters 2025 in the United States

The Siglent Technologies SHS810X Handheld Oscilloscope is a versatile tool that combines both oscilloscope and multimeter functionalities, making it suitable for users like electronics engineers or hobbyists who need portability without sacrificing performance. With a bandwidth of 100 MHz and a sampling rate of 1 GSa/s, it provides solid signal capture capabilities, allowing for detailed analysis of electronic signals. The 5.6-inch TFT-LCD display at 640 x 480 resolution ensures that users can view waveforms clearly, which is a definite plus when working in the field or in varied lighting conditions.

This model features intelligent triggers that include Edge, Pulse Width, and more, enhancing its analytical capabilities. It also supports a range of multimeter functions like DCV, ACV, resistance, and capacitance, which adds to its versatility as a diagnostic tool. The 6000 counts digital multimeter capability is robust enough for most general measurements.

On the downside, the unit's weight at 11.02 pounds may be cumbersome for all users, especially those who need to carry it around frequently. The battery, while having a decent capacity of 6900 mAh, may not last as long under heavy use, so having an external charger handy is recommended. Additionally, since it is designed for general use, it may lack some advanced features that specialized users might seek in higher-end models.

The FNIRSI 2C53T is a versatile handheld oscilloscope-multimeter that caters to professionals, schools, and hobbyists. It features a 50 MHz bandwidth and a 250 MSa/s sample rate, making it suitable for a wide range of applications. The device includes two channels and offers both math operations and cursor measurements, which are beneficial for more detailed analysis. The 2.8-inch LCD display is clear and bright, although some users might find it small for intricate waveform details.

For multimeter functions, it can measure AC/DC voltage up to 999.9 V, current up to 9.999 A, resistance up to 19.99 MΩ, and capacitance up to 99.99 mF, which covers a broad spectrum of electrical measurements. The addition of a signal generator with a maximum output frequency of 50 kHz and 13 waveform outputs is a nice bonus for testing and troubleshooting circuits. Connectivity is facilitated through a Type-C interface, allowing for easy data transfer and charging. The built-in 3000 mAh battery offers up to 6 hours of standby time, which is decent for portable use.

One drawback could be its relatively low record depth of 1 Kpts, which might limit its effectiveness in capturing complex waveforms. Additionally, the device's compact size may make navigation and detailed analysis harder for some users. Nevertheless, its robust feature set and ease of use make it a good choice for users seeking a multifunctional tool.

The Fluke 123B Industrial ScopeMeter is designed for professionals dealing with industrial electrical and electro-mechanical equipment, making it a solid choice for troubleshooting and maintenance tasks. With a bandwidth of 20 MHz and a sample rate suitable for capturing vital signals, it provides decent performance for many applications, particularly in industrial settings. The two input channels allow for comparative analysis, which can be crucial when diagnosing issues. Its dual-functionality as a digital multimeter (with 5,000-count true-rms capabilities) adds versatility, enabling users to measure voltage, current, resistance, and continuity efficiently.

One of the key strengths of this instrument is its rugged design, ensuring durability during field use, which is a significant advantage in industrial environments. The inclusion of shielded test leads helps in obtaining reliable measurements while minimizing interference. The portability of the hand-held design makes it user-friendly for on-the-go troubleshooting.

The Fluke 123B is best suited for professionals needing a reliable, portable oscilloscope-multimeter for everyday industrial applications.
