I. INTRODUCTION

Thank you for selecting the feature-packed Ultrameter III™, one of the
Myron L® Company’s latest in an increasing line of instruments utilizing
advanced microprocessor-based circuitry and SMT manufacturing
processes. This circuitry makes the instrument extremely accurate,
reliable and very easy to use.

The Ultrameter III has been designed to include titration measurements
for Alkalinity, Hardness and an LSI Calculator for water balance analysis.
The Ultrameter III also features Myron L® Company's exclusive Free
Chlorine Equivalent (FC

TM

E

) function for making ORP-based free chlorine
measurements, as well as optional Bluetooth® wireless data transfer.
Other features include a clock with time and date, memory of up to 100
locations with time and date stamp, the ability of the user to adjust the
timeout “Auto OFF”, and enhanced performance. See Features and
Specications on pages 2-3.

The most exciting feature is data logging with the ability to wirelessly
download the memory or stored test data with its corresponding time, date
and unit name (requires -BD option or bluDockTM accessory). This feature
allows the user to create spreadsheets and graphs with ease, and quickly
and accurately manipulate data more effectively. The bluDock's Guardian

TM

application will operate on Windows® 7 or later/macOS® 10.13 or later with
Bluetooth® capability. The data may be exported to spreadsheet formats
such as Microsoft Excel® (.xls and .xlsx) or universal formatting (.csv). The
user can also save data in a secure, encrypted format (.mlcx).
Please Note: Although the Myron L® Company has performed extensive
testing, we cannot guarantee compatibility of all applications and
formats. We suggest testing your application and format for compatibility
before relying on it.

For your convenience, a brief set of instructions is provided on the
bottom side of your Ultrameter III. A Quick Start Guide with abbreviated
instructions is also included with the instrument as a quick reference.

Special note ... Conductivity, resistivity, and TDS require mathematical
correction to 25°C values (ref. Temperature Compensation, pg. 56). On
the left of the Ultrameter III’s liquid crystal display is shown an indicator of
the salt solution characteristic used to model temperature compensation
of conductivity and its TDS conversion. The indicator may be KCl,
NaCl, 442™ or User. Selection affects the temperature correction of
conductivity and the calculation of TDS from compensated conductivity
(ref. Conductivity Conversion to Total Dissolved Solids (TDS), pg. 59).
The selection can affect the reported conductivity of hot or cold solutions
and will change the reported TDS of a solution. Using KCl for conductivity,
NaCl for resistivity, and 442™ (Natural Water characteristic) for TDS is
consistent with present industry practice for standardization. This is how
your instrument, as shipped from the factory, is set to operate. For use in
seawater desalination for example, both the conductivity and TDS may
easily be changed to NaCl.

III. RULES of OPERATION

A. Operation
NOTE: The cell extender does not interfere with normal operation.
Using the instrument is simple:

• Individual or multiple parameter readings may be obtained by
lling individual sensors or entire cell cup area.

• Rinse the conductivity cell and/or pH/ORP sensor well with test
solution 3 times and rell. Temperature and/or measurement
extremes will require additional rinses for maximum accuracy.

• Press the desired measurement key to start measurement.

• For titrations, user intuitive display prompts guide you through
the addition of reagents and measurements.

• Pressing any parameter key again in measurements restarts
the 15 second “Auto off” timer. Pressing any parameter key
again during titrations will cancel the titration in progress.

• Note the value displayed and/or press the MS key to store the

reading (ref. Memory Storage, pg. 36). It’s that simple!

B. Characteristics of the Keys

• Though your Ultrameter III has a variety of sophisticated

options, it is designed to provide quick, easy, accurate

measurements by simply pressing a key.

• All functions are performed one key at a time.

• THERE IS NO “OFF” KEY. If the instrument remains inactive
for 15 seconds after you press any parameter key (user
adjustable up to 75 seconds), the instrument turns itself off.
The instrument turns itself off after 60 seconds of inactivity in
CAL mode, 3 minutes of inactivity in each titration screen and
60 seconds of inactivity in each LSI calculator value screen.

• Rarely is it necessary to press and hold a key (as in Procedure
to Select a Solution, pg. 23; Conductivity or TDS Calibration,
pg. 28; and ORP/FCE Mode Selection, pg. 20).

C. Operation of the Keys (See Instrument Illustration, pg. ii)

1. Measurement Keys in General

Any of the 8 measurement keys turns on the instrument in the mode
selected. The mode is shown at the bottom of the display for COND,
RES, TDS, ORP and pH. The ORP mode is indicated by the units
displayed, mV for ORP or ppm for free chlorine. Measurement units
appear at the right. Pressing any measurement key puts the unit in that
measurement mode even if you are in a calibration sequence and also
serves to cancel a change (ref. Leaving Calibration, pg. 27).

8

2. COND, RES and TDS Keys
These 3 keys are used with solution in the Conductivity Cell.

Precautions:

• While lling cell cup, ensure no air bubbles cling on the cell wall.

• If the proper solution is not selected (KCl, NaCl, 442™ or
User), refer to Why Solution Selection is Available, pg. 23 and
Procedure to Select a Solution, pg. 23.

a. COND Key
Solution to be tested is introduced into the conductivity cell and a press

of displays conductivity with units on the right. On the left is

shown the solution type selected for conductivity.

b. RES Key
A press of

is shown solution type selected for resistivity (ref. Solution Selection,
pg. 23). The range of display of resistivity is limited to between 10
kilohms (KΩ) and 30 megohms (MΩ). A solution outside that range will
only show [- - - -] in the display.

c. TDS Key
A press of

This is a display of the concentration of ionized material calculated from
compensated conductivity using the characteristics of a known material.
On the left is shown solution type selected for TDS (ref. Solution
Selection, pg. 23).

displays resistivity with units on the right. On the left

displays Total Dissolved Solids with units on the right.

3. Alkalinity, Hardness and LSI Keys

The ALK and HARD keys enter the titration measurement functions. The
LSI key also allows you to access the LSI Calculator.

NOTE: All titration measurements require the installation of the cell

extender.

4. pH and ORP/FC Keys

E

Measurements are made on solution held in the pH/ORP sensor well
(ref. pH and ORP/FCE, pg. 62). The protective cap is removed and
the sensor well is lled and rinsed with the sample enough times to
completely replace the storage solution.

After use, the pH/ORP sensor well must be relled with Myron L®
Storage Solution, and the protective cap reinstalled securely (ref.
Maintenance of the pH/ORP Sensor, pg. 11 and Cleaning Sensors, 2.
pH/ORP, pg. 50).

a. pH Key
A press of

b. ORP/Fr Chl Key

In ORP mode, a press of

displays Oxidation-Reduction Potential

/REDOX reading in millivolts; "mV" is displayed. When the FCE mode

is activated, a press of

reading in "ppm" alternating with the FCE predictive ORP reading in "mV".

displays the Free Chlorine Equivalent

5. CAL/MCLR Key
While measuring conductivity, TDS, or pH, a press of

allows

you to enter the calibration mode. Once in CAL mode, a press of this
key accepts the new value. If no more calibration options follow, the
instrument returns to measuring (ref. Leaving Calibration, pg. 27).

If is held down for about 3 seconds, CAL mode is not entered,

but “SEL” appears to allow Solution Selection (ref. pg. 23) with the UP
or DOWN keys. As in calibration, the CAL key is now an “accept” key.

While measuring ORP or Free Chlorine, holding CAL down for about
3 seconds allows ORP/FCE mode selection (ref. pg. 20).

For titrations and LSI Calculator, the CAL key steps you through the
procedure and accepts values for nal calculations.

Once in CAL mode, a press of this key accepts the new value.
While reviewing stored records, the MCLR side of the key is active to
allow clearing records (ref. Clearing a Record/Memory Clear, pg. 37).

6. UP or DOWN Keys
While measuring in any parameter, the or

keys activate

the Memory Store and Memory Recall functions. A single press steps
the display and holding either key scrolls the value rapidly.

10

While in calibration or calculator mode, the keys step or scroll the
displayed value up or down.

While in Memory Recall, the keys scroll the display up and down
through the stack of records (ref. Memory Recall, pg. 37).

IV. AFTER USING THE ULTRAMETER

A. Maintenance of the Conductivity Cell
Rinse out the cell cup with clean water. Do not scrub the cell. For
oily lms, squirt in a foaming non-abrasive cleaner and rinse (ref.
Cleaning Sensors, pg. 50). Even if a very active chemical discolors
the electrodes, this does not affect the accuracy; leave it alone.

B. Maintenance of the pH/ORP Sensor
The sensor well must be kept wet. Before replacing the rubber cap,
rinse and ll the sensor well with Myron L® pH Sensor Storage Solution.
Although not ideal, if Myron L® Storage Solution is not available, you
can temporarily use a strong KCl solution, a pH 4 Buffer Solution, or a
saturated solution of table salt and tap water until pH Storage Solution is
obtained. NEVER use distilled water.

If all ORP solutions are reporting approximately the same value,
clean ONLY the platinum ORP electrode with an MLC ORP
conditioner-soaked cotton swab, being careful not to touch the
swab to the glass bulb of the pH sensor.

V. SPECIFIC RECOMMENDED MEASURING PROCEDURES

A. Parameter Methods
For Conductivity and Total Dissolved Solids measurements, if the
proper solution is not selected (KCl, NaCl, 442TM or User), see Solution
Selection, pg. 23.

III

NOTE: After sampling high concentration solutions or temperature
extremes, more rinsing may be required. When sampling low
conductivity solutions, be sure the pH cap is well seated so that no
solution washes into the conductivity cell from around the pH cap.

B. Titration Methods
For Alkalinity, Hardness titrations, assemble the required materials
before you begin: a pipette with 100µL tips, the required reagents, the
cell extender, and the T-plunger.

11

NOTE: The accuracy of titration measurements

is affected by your technique. Be careful when
removing the cap of the cell extender to add
reagents. Flicking the cap or popping it off can

the cell. Release the plunger button and
let it return to the REST position.

2. T-Plunger Instructions

To PLUNGE the cell:
Clean and dry the T-plunger. With the

cell extender installed and solution in

the cell, insert the tip of the T-plunger
in the cell extender until the arms of the
T-plunger are ush against the rim of the
cell extender. Solution will overow the

cell.

Keeping the arms of the T-plunger ush
against the rim of the cell extender, rotate
the T-plunger from side to side, allowing
the arms of the T-plunger to slide along
the rim of the cell extender.

Remove the T-plunger from the cell by
lifting it straight up out of the cell, being
careful to keep it centered over the mouth
of the cell extender. When the T-plunger
is completely out of solution, tap the
T-plunger on the inside rim of the cell
extender to dispel any clinging solution
back into the cell.

Insert the T-plunger all the way

G. LSI Calculator Functions
The Ultrameter III features an LSI Calculator that can be used to perform
actual LSI or for hypothetical water balance calculations.

The LSI Calculator computes a Langelier Saturation Index value using
measured, default, or user-adjusted values for alkalinity, hardness, pH
and temperature.

If you have stored alkalinity, hardness or pH and temperature values,
the calculator will automatically display the most recent stored value. All
other values will display as default. You can adjust any or all of the values
displayed to determine the effect of the change(s) on the LSI value.

1. Measuring LSI
To compute the actual saturation index of a solution:

Before you enter the calculator function, you must measure and store
values for all water balance variables used by the calculator to compute

saturation index.
