1.0 PURPOSE

This procedure describes the activities necessary for measuring the Oxidation-reduction potential (ORP) in unfiltered water samples during water quality monitoring activities at the Cotter Corporation (N.S.L.) (“Cotter”), Canon City Milling Facility.

2.0 SCOPE

This procedure applies to oxidation-reduction potential (ORP) measurements within a millivolt range of +/- 1999.9 mV in water samples taken for water quality measurements by Cotter Corporation (N.S.L.), Canon City Milling Facility.

3.0 REFERENCES

4.0 DEFINITIONS

4.1 Oxidation-reduction potential (ORP) measurements are used to monitor chemical reactions, quantify ion activity or determine the oxidizing or reducing properties of solutions. While ORP measurements are somewhat similar to those of pH, the potential value must be carefully interpreted to achieve meaningful results. The field measured ORP values are corrected to correlate to Standard Hydrogen Electrode (SHE).

10.4 If the mV meter will not calibrate refer to the specific meter/instrument operating instruction manual for troubleshooting and maintenance information or replace the meter or probe with a spare meter or mV probe.

11.0 MEASUREMENT INSTRUCTIONS

Direct measurements for ORP are made by simply taking a measurement of a sample, correcting to units of Standard Hydrogen Electrode (SHE) and reporting a result.

11.1 Direct Measurement Of Samples.

11.1.1 Insert a proper functioning electrode into the water sample to be measured.

11.1.2 Take a reading in mV by following the directions in the pH/mV meter

operator's manual.

11.1.3 When the reading stabilizes, record the sample temperature and mV value

as displayed on the meter.

11.1.4 It is necessary to report the value relative to the results achieved by a

"normal standard hydrogen electrode" as the reference electrode. To do this you must add the observed mV result to the potential of the reference electrode being used - in this case a 4 M KCL with Ag/Ag CI electrode, which has a value of 200 mV at 25o C. This is necessary since the value of the "normal standard hydrogen electrode” is defined as having a value of

0.0 mV under the same conditions.

11.1.5 Refer to appendix 5.1 for the offset correction factor to use for

measurements at temperatures different than 25oC Where

Eh = the value of the potential of the sample relative to the “normal standard hydrogen electrode”

Eo = the potential observed with the ORP electrode (the result from the meter)

11.1.6 Cf = Correction Addition Factor is the constant offset factor in potential

due to the reference electrode in use (in this example 200 mV for a temperature of 25oC).

11.1.7 If your meter reported a value of 450 mV at a temperature of 25oC, your

reported result would be Eh = 450 + 200, or 650 mV (SHE). If the value reported was -599 at a temperature of 25oC your reported result would be Eh = -599 + 200, or -399 mV (SHE).

Introduction

Congratulations! You have selected a VWR® sympHony™ meter designed for electrochemistry measurements in the field or in the laboratory.

• Single parameter meters provide single measurement of pH, dissolved oxygen,

or conductivity.

• Dual parameter meters provide dual measurements of pH/dissolved oxygen,

pH/conductivity, or pH/ISE (ion selective electrode).

• Multiple parameter meters provide multiple measurements of pH, ISE, dissolved

oxygen, and conductivity.

All meters include a temperature measurement function. All meters with pH measurement capability include a mV/relative mV/ORP function.

Convenient Meter Features

Built to meet the demands of busy, multiple user laboratories or plant environments, all meters are microprocessor controlled aiding in the delivery of accurate and precise measurements. To better meet the needs of users in environmental protection and control, food and beverage, pharmaceutical, and consumer product laboratories, the sympHony meters include these key features:

• Password Protected Methods – The meter will save up to ten custom

measurements and calibrations for future reference. Password protection of the setup menu eliminates any tampering with methods as multiple users access only the procedure most appropriate to their work.

• AUTO-READ™ – The meter will take a measurement and automatically print or

log the data when the reading becomes stable. The measurement is frozen on the display until the user prompts the meter to take a new measurement.

Page 16

sympHony™ Meter User Guide

• Stirrer Control – Benchtop meters have a control for the stirrer probe and the

AUTO-STIR™ BOD probe, eliminating the need for additional stir plates and bars.

• Display Backlight – When the meter is on, a quick press of will turn

the backlight on and off. When the meter is operating on battery power, the

backlight will automatically turn off after two minutes to conserve power. When

batteries are low, the backlight will no longer turn on.

• Automatic Shut-off – All sympHony meters will shut down after 20 minutes

without a keypress. This maximizes battery power on portable meters and

benchtop meters that are being run on battery power.

• Audible Signals – The meter will beep whenever a key is pressed, providing

immediate verification that the user’s input was received.

• Visual Alarm Signals – Flashing and icons indicate that calibration

settings need adjustment. For more detail, refer to subsequent sections of this

user guide that discuss specific measurement techniques.

An easy-to-use reference guide, attached to each meter, supports daily meter use.

Preparation

Installing the Power Adapter

The universal power adapter that is included with your benchtop meter is the only power adapter recommended for use with this unit. The use of any other power adapter will void your meter warranty. The external electrical power adapter is rated to be operated at 100 to 240 VAC, 0.5 A, 50/60 Hz.

Based on your wall outlet, select one of the four plug plates provided (110 V, 220 V, 240V) and slide it into the grooves on the adapter. A click will be heard when the plug is properly in place.

Connect the output plug of the power adapter to the power input on the benchtop meter. Refer to the diagram in the Connecting the Electrodes section.

Batteries can be installed in the benchtop sympHony meters, so the meter setup settings are protected if the meter is disconnected from the wall outlet or a brief power outage occurs.

Page 22

sympHony™ Meter User Guide

Installing the Batteries

The sympHony meters use four AA alkaline batteries. Do not use lithium or rechargeable batteries. Improper installation of non-alkaline batteries could create a hazard.

Note: For benchtop meters, the installation of batteries is not required if the unit will always be connected to a power source via the universal power supply. For portable meters, the batteries are supplied from the factory. To access the battery compartment in portable meters, loosen the two screws in the back of the meter.

1. Confirm that the meter is off and gently place the meter upside down on a

clean, lint-free cloth to prevent scratching the display.

2. Remove the battery case cover.

3. Insert new batteries with the + side orientation as depicted in the battery

compartment housing.

4. Replace the battery case cover.

5. Stored data, calibrations and methods will remain in the meter’s nonvolatile

memory when the batteries are being replaced. However, the date and time

may need to be reset when the batteries are changed.

Dissolved Oxygen Calibration

• Prior to calibration, the dissolved oxygen probe must be prepared and polarized.

The probe is continuously polarized when it is connected to the meter. When

the probe is first connected or if the probe is disconnected for more than 60

minutes, connect the probe to the meter, connect the meter to a power source

and wait 30 to 60 minutes for the probe to polarize. Disconnecting the probe for

less than one hour will require 5 to 25 minutes for polarization.

• The meters will supply a polarization current to the dissolved oxygen probe even

when the meter power is off. To maximize the meter battery life, unplug the

probe if it will not be used for an extended period.

1. Select one of the following calibration modes in the setup menu.

– An air calibration is performed in water saturated air using the

calibration sleeve. This is the simplest and most accurate calibration. Due to

the inherent differences between water saturated air and air saturated water,

102.3% saturation will be displayed when the calibration reading is stable.

i. The highest possible accuracy is reached when calibration temperature is

the same as the measuring temperature.

ii. Moisten the sponge or absorbent cloth in the calibration sleeve with

distilled water and insert the probe into the sleeve without touching the

water saturated material. For BOD measurements, this calibration can be

performed in a BOD bottle.

– A water calibration is performed using water that is 100% saturated

with air. Bubble air into a water sample and gently stir the sample to prevent

the buildup of air bubbles on the dissolved oxygen probe membrane.

c. – A manual calibration is performed using a water sample with a

known concentration of dissolved oxygen. This method can be used to

calibrate the dissolved oxygen probe to the value achieved by a

Winkler titration.

Dissolved Oxygen Technique

Page 39

sympHony™ Meter User Guide

i. A manual calibration involves performing a Winkler titration and using

that sample as a calibration standard. The oxygen level result from the

titration is entered in a manual calibration as the dissolved oxygen value.

This correlates the meter input to the Winkler titration. This method is

inherently less accurate, due to the possibility of titration errors.

– A zero point calibration is performed in an oxygen-free solution. A

zero point calibration is not generally required unless measurements will

be taken below 5% saturation or 0.5 mg/L. Zero the probe when using a

new membrane, using fresh filling solution or when measuring dissolved

oxygen levels below 1 mg/L or 10% saturation. An air calibration should be

performed prior to the zero point calibration.

2. Allow the probe and calibration standard (water saturated air, air saturated water,

Winkler standard or oxygen-free solution) to reach equilibrium.

3. In the measurement mode, press until the arrow icon points to the bottom

line, press until the % sat or mg/L icon is shown and press to begin

the calibration.

4. Wait for the dissolved oxygen reading to stabilize.

a. If an air calibration is performed, the meter will display 102.3% and

automatically return to the measurement mode.

b. If a water calibration is performed, the meter will display 100.0% and

automatically return to the measurement mode.

c. If a manual calibration is performed, wait for the

mg/L icon to stop flashing

and enter the dissolved oxygen value by pressing

until the first digit to

be changed is flashing, press / to change the value of the flashing

digit and continue to change the digits until the meter displays the correct

dissolved oxygen value. Once the dissolved oxygen value is set, press

until the decimal point is in the correct location.

d. If a zero point calibration is performed, the meter will display 0.00 and

automatically return to the measurement mode.
