10 Best Capacitor Testers 2025 in the United States

The B&K Precision 891 Benchtop LCR Meter is a versatile and accurate tool for measuring inductance (L), capacitance (C), and resistance (R). It offers a wide capacitance range, making it suitable for a variety of testing needs in both professional and industrial settings. The high test frequency of up to 300 kHz ensures precise measurements, which is essential for detailed analysis and diagnostics.

The Fluke 117 Digital Multimeter is a versatile tool that includes capacitance measurement among many other functions, making it a good choice if you want a multi-purpose device rather than a dedicated capacitor tester. It offers a decent capacitance range with an accuracy of about +/-0.5%, which is reliable enough for most professional and home repair tasks. The large backlit digital display makes reading measurements easy, especially in low-light environments. A notable strength is its True RMS capability, which ensures accurate readings even with complex electrical signals, plus features like Low Input Impedance help avoid false readings from stray voltages.

The Fluke 15B+ Digital Multimeter is a solid choice for those looking to perform a variety of electrical measurements, including capacitance testing. With a capacitance range that caters to many everyday uses, this multimeter stands out for its ability to measure AC/DC voltage up to 1000V and current up to 10A, making it quite versatile for both residential and commercial electrical applications.
