B&K Precision 879B Handheld LCR Meter with ESR

Troubleshooting faulty capacitors or matching precise inductors can stall an entire repair bench when standard multimeters fail to read internal component health. The B&K Precision 879B Handheld LCR Meter with ESR, removes all guesswork from component testing. This high-accuracy, 40,000-count handheld LCR meter measures inductance, capacitance, and resistance with absolute bench-class precision, while adding a dedicated Equivalent Series Resistance (ESR) calculation mode to instantly expose dried-out or failing capacitors before they cause board failure.

Engineered for field technicians and lab engineers alike, the unit operates across selectable test frequencies up to 10 kHz, utilizing an automatic ranging architecture to deliver immediate, accurate readings. The dual display layout simultaneously tracks primary measurements alongside secondary factors like Quality (Q), Dissipation (D), or Theta calculation angles. Outfitted with a convenient mini-USB data interface, you can effortlessly log your component data directly to a PC for comprehensive quality control tracking and component grading.

Highlights:

• Advanced ESR Diagnostic Mode: Measures Equivalent Series Resistance directly, letting you accurately spot failing or degraded capacitors in-circuit.

• Dual Parameter Display: High-resolution screen tracks primary values (L/C/R) and secondary characteristics (Q/D/Θ) simultaneously for faster analysis.

• Multi-Frequency Versatility: Selectable test frequencies at 100 Hz, 120 Hz, 1 kHz, and 10 kHz match precise manufacturer testing conditions.

• Fast Automated Ranging: Smart internal processor shifts ranges automatically to lock in maximum resolution and accuracy without manual clicking.

• Seamless PC Data Logging: Built-in mini-USB port allows direct connection to laptops for automated data collection and component validation.
