Precision Conductivity Meter

For the determination of the “rest” electrical conductivity of aviation fuels and other similar low-conductivity hydrocarbon liquids in the range from 0.1 to 2000 pS/m

  • Capable of being modified to provide higher conductivity ranges
  • Optional capability to measure sample temperature
  • Mechanical design of the Conductivity (KSLA) Cell allows accurate self measuring of the test sample volume (100 mL)
  • Electronic circuitry automatically samples and holds the reading
  • Large five digit liquid crystal display
  • Internal self check calibration of all electronic circuits
  • Ease of disassembly and cleaning of the Conductivity Cell
  • Completely self contained powered by 6 standard 9 volt batteries monitored by a low battery indicator

A specific volume (100-mL) of test sample is introduced between the two concentric electrodes in the Cell. Using a triaxial cable, the Cell is connected to a sensitive dc ammeter in the Console and a dc voltage is applied between the two electrodes. Due to the physical geometry of the Cell, the Cell constant is stable and calculable. Thus, the resultant peak current is readily transformed and digitally displayed as picosiemens per meter (pS/m), also commonly known as conductivity units (CU). As defined in ASTM Standard Test Method D 4308, a CU is equal to a picosiemen per meter (1 CU = 1 pS/m). The enclosure technique employed in the Cell precludes the need for external screening from stray electrical fields.
