Portable Digital Conductivity Meter

Description

The portable digital conductivity meter provides a measurement of electrical conductivity of fluids in conductivity units (CU), which are defined as picosiemens per meter in ASTM D2624. The rugged electro/mechanical design facilitates ease of use for both laboratory and field applications. The meter was designed and developed for safety reasons to measure the electrical conductivity of hydrocarbon fuels, particularly jet fuels. Additional pre-amp versions are available to accommodate measurement of a variety of fluids for different applications.  The portable digital conductivity meter consists of an electronics assembly and a stainless steel probe. The probe, which is similar to a capacitor having concentric electrodes, is immersed into the fluid, up to the set of holes. During the read cycle a relatively small direct current flows through the fluid between the electrodes. The current is amplified in the electronics assembly and is displayed on the liquid crystal display in picosiemens per meter (pS/m). This data is then stored in non-volatile memory and can be retrieved until the next read.

TEST METHOD:

For determination of the electrical conductivity of aviation and distillate fuels with and without a static dissipater additive. The test normally gives a measurement of the conductivity when the fuel is uncharged, that is, electrically at rest (known as the rest conductivity).

FEATURES:

Continuous standard electrical conductivity range from 0 to 2000 picosiemen per meter (pS/m)

Available in other conductivity ranges

LED illuminates during automatic test cycle (3 seconds)

Temperature measured and displayed in Celsius and Fahrenheit

Data stored (nonvolatile) until next test cycle is performed
