72C - Boonton Capacitance Meters

Get Quote

  • Model: 72C
  • Manufactured by: Boonton
  • Basic Accuracy: 0.005
  • Highest Range: 3000 pF
  • Digits: Analog
  • Extra Specifications: CAPACITANCE METER 100 kHz MHZ

This 100 kHz analog meter is recommended for series capacitance measurements on very low capacitance junctions where normal series loss can cause the Q of the junction capacitance to fall well below 10 at 1 MHz. In this instance, using 72C takes advantage of the fact that the Q of the cpacitor with series loss is inversely proportional to frequency and therefore ten times higher at 100 kHz then at to 1 MHz.

  • 0.5% basic accuracy
  • DC bias up to 300 V
  • 3-terminal measurement
  • Differential inputs
  • 15 mV test level
