A precision microprocessor-based instrument for determining salt content,
conductance, and temperature of crude oil samples in accordance with ASTM
D3230. The analyzer measures conductivity over three ranges ( 0-2, 2-20,
20-200 µS) with automatic range selection. Temperature is measured in the
range of -5 to 55°C. Reports conductivity at the temperature of measurement
and conductivity corrected to 25°C, allowing for standardization of field
measurements at different temperatures. Salt content is obtained by reference
to a calibration curve of conductivity versus salt content of known mixtures.
All functions including calibration are controlled by simple keypad entries.
Compact design makes this unit ideal for laboratory or field applications.
Includes signal processor, display module, temperature / conductivity probe
with three-foot cable, 100mL tall-form sample beaker, 9 volt battery, 115 or
220 VAC adapter, and padded nylon carrying case.
The advanced model utilizes the latest low-voltage, synchronous detection
technology with a high-precision 18-bit analog-to-digital converter for
conductivity measurements and a high-accuracy thermistor array to measure
sample temperature. Automatically calculates salt concentration directly from
acquired temperature and conductivity values. Measures conductivity over four
ranges 0-2, 2-20, 20-200, and 200-1500 µS with automatic range selection.
Self-calibration feature allows operator to adjust for any drift without
re-entering standard temperature curves. Complete data storage of test
results with 24Kb RAM for about 500 test results. Test data can be easily
uploaded in a comma delimited format to a PC with Windows® 95/98/NT-based
software via an RS232 serial data port. Easy-to-read alpha-numeric display
shows any four of the following parameters at one time as chosen by the
operator: salts, conductance, conductance @ 25°C, pH, pH millivolts,
temperature (°C or °F), internal and external battery voltages, date, time,
logging ID, and ID increment value. Portable for field or laboratory testing
with up to 8 hours of continuous operation from internal Ni-Cd rechargeable
batteries on advanced model. Extended battery-powered operation option
