BK Precision Component Testers

Model 878  ---

Dual-Display Autoranging LCR Meter 

The 878 measures capacitance, resistance, and inductance. Components can be measured in the series and parallel mode as desired. The full 4-digit display reads values to 9999 on each range. The instrument is autoranging; or manual ranging may be selected. The instrument prompts the user when calibration is needed, and the dual display shows whether to calibrate with an open or short. 
  • Simultaneously displays measured value and Q or dissipation factor 
  • Min/Max average 
  • Relative mode 
  • Tolerance test 
  • Two selectable test frequencies (120 Hz, 1 kHz)

Low-Ohm LCR Meter

The rugged 875B LCR is a reliable easy-to-use workhorse that will measure inductors, resistors and capacitors quickly and accurately. Utilizing special circuitry, the measurement more closely replicates true in-circuit measurements. Ten range resistance range measures to 0.001 - zero adjust removes leads resistance. 
  • Precision measurement of very low resistances 
  • Measures D (dissipation factor) 
  • Unique drop-proof construction 
  • Tilt stand
