CALIBRATION SOLUTION:

See our General Catalog for available Conductivity Calibration
Solutions.

INTRODUCTION:

The model 19060-00 is a bench top microprocessor based multifunction
meter designed for the measurement of conductivity and temperature of
aqueous solutions. This conductivity meter has six ranges, each from 0
to 3300 counts and is displayed on a large sixteen character dot matrix
liquid crystal display. All instruments are shipped from the factory
for 115 VAC line operation. The power entry module on the rear panel
can be easily changed for 230 VAC operation when necessary.

This meter features four front panel controls, one for manual range
selection or auto ranging. One for function selection of conductivity,
resistivity, TDS, self-test or standby. One for parameter selection of
reference temperature, temperature coefficient, cell constant and TDS
multiplier. The last front panel control is for the display and setting
of the parameters as well as transmit on command (transmit on command
for model 19060-10 only).

INTRODUCTION CONTINUED:

The model 19060-10 has an additional function of Salinity, RS232 output
for a serial printer or PC data display, logging and printing. An
analog output of conductance and temperature for strip chart recording.

CONDUCTIVITY:

The basic unit of resistance is the ohm, conductance is the reciprocal
of resistance, its basic unit of measurement is the mho (international
system of units for mho is Siemens [S]).

In the measurement of aqueous solutions, conductivity is based on the
reciprocal of the resistance of a 1-cm cube of material measured between
opposite faces. This is a cell constant of 1. Conductivity cells
usually consist of two metallic plates of a determined size mounted in a
defined area. The cell constant “K” is the length “L” (or distance
between the plates) of the conducting path in centimeters divided by the
effective cross sectional area “A” of the conducting path in square
centimeters (K=L/A). The resistance of conductor is inversely
proportional to its cross sectional area and directly proportional to
its length.

The model 19060-00, -10 is designed to use a cell with a constant of 10
cm-1. The instrument’s cell constant parameter setting is adjustable
from 8.00 to 12.00.

Conduction in aqueous solutions is by ionic movement and increases with
temperature. This change is expressed in percent per degree “C”

relative to a reference temperature normally 25.0°C and is commonly
called the slope.

The model 19060-00, -10 has Automatic Temperature Compensation for slope
correction with reference temperature parameter adjustable from 12 to

28°C, temperature coefficient parameter adjustable from 0 to 12.5% per
degree C and displays conductivity in mS or mS.

RESISTIVITY:

The model 19060-00, -10 displays resistivity as a reciprocal of the
conductivity. Resistivity’s basic unit of measurement is the ohm.

Model 19060-00, -10 displays resistivity in MW and KW.

TOTAL DISSOLVED SOLIDS:

The Total Dissolved Solids (TDS) in a solution does not change with
temperature. Conductivity is sensitive to temperature. The Model
19060-00, -10 automatically calculates the TDS from the conductivity
reading by applying the appropriate factor that the user sets or by
using the preset parameter. The TDS multiplier is adjustable from 40%
to 125% and displays TDS in PPM (Parts P
Thousand).
