Model 1154 Precision Conductivity Meter(ASTM Standard Test Method D4308)
Four standard ranges provide high resolution and accurate direct measurement of electrical conductivity of fluids from.01 to 200,000 picosiemens per meter (pS/m)Capable of being modified to provide higher conductivity rangesOptional capability to measure sample temperatureMechanical design of the Conductivity (KSLA) Cell allows accurate self measuring of the test sample volume (100 mL)Electronic circuitry automatically samples and holds the readingLarge five digit liquid crystal displayInternal self check calibration of all electronic circuitsEase of disassembly and cleaning of the Conductivity CellCompletely self contained powered by 6 standard 9 volt batteries monitored by a low battery indicatorApplicationsMany applications require highly accurate “rest” electrical conductivity measurements of fluids ranging in values from less than one pS/m to several thousand. “Rest” conductivity is the electrical conductivity at the initial instant of current measurement after a dc voltage is impressed between electrodes (reciprocal of the resistance of uncharged fluid in the absence of ionic depletion or polarization). The Precision Conductivity Meter was originally designed to precisely measure the conductivity of hydrocarbon fuels only. Limiting factors are the viscosity of the fluid and the conductivity level to be measured. However, electrical conductivity of other fluids can be measured and/or ranges of the instrument can be modified by Emcee to accommodate higher conductivity values than the standards offered.Theory of OperationA 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.
