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).

CONDUCTIVITY CELLS:
There are several types of conductivity cells available. The (Au) cell
is recommended for measurements below 3.3 mS. The (Au) multipurpose
cell in the flow configuration is recommended for ultra pure water (grab
samples of ultra pure water are subject to contamination from the vessel
used and atmospheric gases). The (Au) cell has much less tendency to
carry over solution from one measurement to the next. The (Au) cells
require less maintenance than the (Pt) cells but the linearity is not
guaranteed above 3.3 mS.
CONDUCTIVITY CELLS CONTINUED:
The (Pt) cells are needed for measuring solutions with conductivity
readings above 3.3 mS. The (Pt) cells will require replatinizing on
occasion. Anytime a (Pt) cell is cleaned it should be replatinized.
This can be accomplished by sending the cell to the manufacturer or the
user can replatinize the cell with the Model 01481-11 Platinizing
Station and with Platinizing Solution (ASTM D1125).
10
Page 12
It is important to remember that the conductivity cell is delicate and
should be cared for properly. Before using your cell it should be
rinsed in tap or deionized (DI) water if available. Carefully, shake
off excess and dry with a clean lab wipe.
If possible, rinse cell in a sample of the solution to be measured
before the actual measurement is made. Once the cell is placed in the
sample for measurement, it is helpful to agitate the cell by moving up
and down a few times. This will aid in dislodging any air bubbles.
Allow sufficient time for temperature equilibration before recording
measurement. When finished using the cell, rinse in an appropriate
solvent and dry. The cell may be stored dry.
CLEANING CELLS:
To clean a conductivity cell, wet a cotton tipped applicator with a
solvent appropriate to remove any residue that has contaminated the
plates of the cell. Choose a solvent (ie: Isopropanol 99%) that will
not damage the epoxy tube the cell is constructed of (do not use Aqua
Regia to clean cell or remove old platinum). Insert the wetted swab
through the cell. You may need to do this several times until the swab
shows no residue. Then clean with a mild detergent and warm DI water.
Clean cell only when necessary. Remember, if it is a (Pt) cell, it will
need to be replatinized after it has been cleaned.
NOTE: A clean dry cell will display no more than 1 digit on any range
after auto zero check.
The conductivity dip cell should be immersed in the solution a minimum
of 1.5 inches for proper measurement.
Multipurpose cells are combination dip and flow cells. The outside
diameter (OD) of the cell is 7/16” or .4375”. To connect flexible
tubing to the cell for an inline flow, use 7/16” inside diameter (ID)
tubing. Using the cell in a flow configuration is recommended for
measurements of ultra pure water.
For convenience, the instrument features a built-in cell holder. An oring on the conductivity cell allows the cell to be vertically
positioned in the cell holder.
TO READ CELL CONSTANT:
METHOD 1:Turn Function to SELF TEST and read cell constant on
display.
METHOD 2:Turn Parameter to CELL CONSTANT, push the PUSH TO DISPLAY
knob and the cell constant will display momentarily.
CELL CONSTANT ADJUST:
To observe and adjust the cell constant if necessary:
Turn Function to SELF TEST
Turn Parameter to CELL CONSTANT
Push, PUSH TO DISPLAY knob until L.E.D. lights (2 second delay)
By turning PUSH TO DISPLAY knob, the user can adjust the cell constant
between 8.00 and 12.00.

CALIBRATION: STANDARDIZE/CALIBRATE INSTRUMENT AND CELL
STEP 1:
Select a Conductivity Standard Solution of a known value above 50 mS
(values less than 50 mS are not always reliable). Rinse three (Clean)
test tubes with a small amount of the standard solution then discard the
rinse solution. Fill the three test tubes with the standard solution to
a depth of 30 mm. Hold the three test tubes at 25°C (if practical).
Soak your cell in deionized (DI) water for 5 minutes (this allows the
plates of cell to be wetted).
For this example we will use a 1409 mS/cm Calibration Standard Solution.
STEP 2:
Plug conductivity cell into meter. Turn power ON (power cord connected
to meter and AC outlet). POWER ON RESET will display (all parameters
reset to preset value).
Turn Range to AUTO
Turn Function to CONDUCTIVITY
Turn Parameter to CELL CONSTANT
Dip cell into 1st test tube sample of standard solution. Agitate cell
with gentle up and down motion and then wait for temperature to
equilibrate. Remove cell and carefully shake off excess.
Dip cell in 2nd test tube for 10-15 seconds, remove and shake off
excess.
Dip cell in 3rd test tube and push, PUSH TO DISPLAY knob (cell constant
will display momentarily) when L.E.D. light comes on, turn knob to make
display read the value of the calibration solution (example 1409 mS).
The instrument with cell has now been standardized (calibrated) to a
known value of solution. Use STANDBY mode to retain parameter settings.
NOTE: If power to instrument is removed, parameter settings will return
to preset values when instrument power is returned.
MAKING CONDUCTIVITY MEASUREMENTS:
Standardize/calibrate the instrument and cell using a conductivity
standard (see previous page).
Select AUTO RANGE or appropriate manual RANGE, set REFERENCE TEMPERATURE
if different than 25.0°C. Set TEMPERATURE COEFFICIENT if different than
1.91%. Rinse cell in DI water, then rinse cell in a portion of unknown
sample if possible. Wait for temperature equilibration of cell to
