Precision Conductivity Meter

Description

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.

TEST METHOD:

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.

FEATURES:

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
