GENERAL DESCRIPTION

HI 8510, HI 8512, HI 8710, HI 8711, HI 8720, HI 931500, HI931501 and HI 932500 are pH-

ORP panel-mounted indicators and controllers designed for simplicity of use in a wide range of industrial process applications.

The models are designed with DIN standard panel mount with membrane keypads on the front panel, a large LCD display and autodiagnostic functions (not HI 931500, HI 931501 and HI 932500).

Connections to the power supply, contacts and recorders are made through screw terminals on the rear panel.

Two models are available for HI 8510, HI8711, HI 8512, HI 8520. The E-model accepts input direct from the pH or ORP electrode, while the T-model accepts a 2-wire current loop of 4 to 20mA from a pH or ORP transmitter.

HI 931500, HI 931501 and HI 932500 are equipped with a BNC socket to connect a pH-ORP electrode.

Other features include: recorder output in 0 to 20mA or 4 to 20 mA; LED indicators which identify the controller mode.

Using the pH indicators in conjunction with a 4-20mA output pH transmitter HI 8614 or HI 8614L (with LCD display) and using the ORP indicators in conjunction with a 4-20 mA output ORP transmitter HI 8615 or HI 8615L (with LCD display) will assure you of a strong, interference-free signal at distances up to 300 m (1000 ft).

All instruments are supplied with a plastic transparent front cover and mounting brackets (electrode and mains cable excluded).

MECHANICAL DIMENSIONS

The meters have a DIN 43 700 casing in black anodized aluminum. Front and back of the instruments are supplied with shockproof ABS plastic and a transparent protective cover for the front panel.

INITIAL PREPARATION

• Connect a 3-wire power

cable to the 4-screw terminal strip; according to the voltage level as indicated and pay particular attention to the correct live, earth and neutral terminal connections.

• For Model E, HI 931500, HI931501 and HI 931500

connect the pH or ORP electrode to the BNC marked "ELECTRODE INPUT".

• For Model T, connect the 2 signal wires of the pH or ORP transmitter to the terminal marked "IN/OUT TRANSMITTER" paying particular attention to the indicated polarity.

• Recorder Terminals: these contacts are the output terminals for connection to a recorder. The output is from 0 to 20 mA / 4 to 20 mA as indicated and is proportional to the measured pH or ORP value.

• PT 100 Terminals: these contacts connect the PT 100 temperature sensor for automatic temperature compensation of pH measurement. If temperature compensation is not required, connect a 110 Ohm, 0.25W resistor across the terminals (equivalent to a fixed temperature of 25°C/77°F).

controllers for dosing either acid or alkaline liquid.

If you plan to dose acid (e.g. in Hexavalent Chromium reduction), make an open circuit between ACID/BASE selection terminals (see rear panel descriptions #3 at page 12-13 and #4 at page 23). If you plan to dose alkaline (e.g. in Cyanide oxidation product), make a short circuit across the above mentioned terminals.

• HI 8720 and HI 932500 are single dosage

controllers for dosing either oxidant or reductant liquid.

If you plan to dose oxidants (e.g. in cyanide oxidation), make an open circuit between oxidation/reduction selection terminals (see rear panel descriptions #3 at page20-21 and #4 at page 28).

If you plan to dose reductants (e.g. in hexavalent chromium reduction), make a short circuit across the above mentioned terminals.

• Set Contacts (HI 8710,

HI 8720, HI 931500 and HI 932500 only): these con-

tacts (maximum 2A, 220 V) are for connection to the dosing pump to dose either acidic or alkaline liquids (HI 8710 and HI 931500 only) or to dose either oxidizing or reducing chemicals (HI 8720 and HI 932500 only). These contacts act only as a switch for the power to the drive.

• Base contact (HI 8711 and HI 931501 only): these two

contacts are for the connection to the dosing pump for the base. They act as a switch for the power to the drive.

• Consent Contacts (HI 8710, HI 8720, HI 931500 and HI932500 only): these con-

tacts (maximum 2A, 220V) are used for reduction and oxidation reactions when the pH controller is used in conjunction with an ORP Controller and viceversa. In these applications, the consent contacts of both meters are connected together to link the ORP and pH controllers so that ORP dosage will occur only if the actual pH value is correct. This is to avoid overdosage of oxidants or reductants which may lead to undesirable pollution. The "Consent" contacts can be left open if HI 8710 or HI 931500 are used independently as pH controllers only. The "Consent" should be shorted if HI 8720 or HI 932500 are used independently as ORP controllers only.

• Alarm Contacts (HI 8710, HI 8711 and HI8720 only): if

the measured pH or ORP is not within the tolerance of the set value, the alarm contact is closed. This can occur if there is insufficient dosage or if there is overdosage.

Note: all external cables to be connected to the rear

panel should be ended with cable lugs.

OPERATIONAL GUIDE

TAKING REDOX MEASUREMENTS

Redox measurements allow the quantification of the oxidizing or reducing power of a solution, and are commonly expressed in mV.

Oxidation may be defined as the process during which a molecule (or an ion) loses electrons and reduction as the process by which electrons are gained.

Oxidation is always coupled together with reduction so that as one element gets oxidized, the other is automatically reduced, therefore the term oxidation-reduction is frequently used.

Redox potentials are measured by an electrode capable of absorbing or releasing electrons without causing a chemical reaction with the elements with which it comes into contact.

The electrodes most usually available for this purpose have gold or platinum surfaces; gold possesses a higher resistance than platinum in conditions of strong oxidation, while platinum is preferred for the measurements of oxidizing solutions containing halides and for more general uses.

When a platinum electrode is immersed in an oxidizing solution a monomolecular layer of oxygen is developed on its surface. This layer does not prevent the electrode from functioning, but it increases the response time. The opposite effect is obtained when the platinum surface absorbs hydrogen in the presence of reducing mediums. This phenomenon is rough on the electrode.

To make correct redox measurements the following conditions must prevail:

- The surface of the electrode must be

cleaned and smooth.

- The surface of the electrode must un-

dergo a preventive treatment depending on the solution to be measured has oxidizing or reductive characteristics.

Because the Pt/PtO system depends on the pH, the pretreatment of the electrode may be determined by the pH and the redox potential of the solution to be measured.

As a general rule, if the ORP mV reading corresponding to the pH solution value is higher than the value in the Table below, an oxidizing pre-treatment is necessary; otherwise a reducing pre-treatment is necessary:

pH m V pH mV pH mV pH mV pH mV 0 990 1 920 2 860 3 800 4 74 0 5 680 6 640 7 580 8 520 9 46 0 10 400 11 340 12 280 13 220 14 16 0

Reducing pre-treatment: immerse the electrode for some minutes in HI 7091.

Oxidizing pre-treatment: immerse the electrode for some minutes in HI 7092.

If the pre-treatment is not performed, the electrode will take significantly longer to respond.

When working with electrodes of the refilling type, the electrolyte used for filling must be constantly kept at an adequate level (no less than 2½ centimeters from the filling hole) and topped up if necessary with HI 7071 refilling solution.

In the event that measurements are performed with solutions containing sulfides or proteins, the cleaning of the diaphragm of the reference electrode must be performed (see page 20, "Cleaning Procedure").

In order to have a correct functioning of the ORP electrode, immerse it into HI 7020 and measure the response; the obtained value should be within 200 and 275 mV.

After this functional test, it is suggested to wash the electrode thoroughly with water and proceed to the oxidizing or reducing pretreatment before taking measurements.

When not in use, the electrode tip should be kept moist and far from any type of mechanical stress which might cause damage. For this reason, the use of the protective cap supplied with the electrode and filled with HI 70300 storage solution is advised.

PREPARATION

Remove the protective cap. DO NOT BE ALARMED IF ANY SALT DE-

POSITS ARE PRESENT. This is normal with electrodes and they will

disappear when rinsed with water. During transport tiny bubbles of air may have

formed inside the glass bulb. The electrode

cannot function properly under these conditions. These bubbles can be removed by "shaking down" the electrode as you would do with a glass thermometer.

If the bulb and/or junction are dry, soak the electrode in HI70300 Storage Solution for at least one hour.

For refillable electrodes:

If the fill solution (electrolyte) is more than 1 cm (½") below the fill hole, add HI7082 3,5M KCl Electrolyte Solution for double junction or HI7071 3,5M KCl+AgCl Electro- lyte Solution for single junction electrodes. For a faster response unscrew the fill hole screw during measurements.

For AmpHel® electrodes:

If the electrode does not respond to pH changes, the battery is run down and the electrode should be replaced.

MEASUREMENT

Rinse the electrode tip with distilled water. Immerse the tip (4 cm / 1½") in the sample

and stir gently for approx. 30 seconds. For a faster response and to avoid cross

contamination of the samples, rinse the electrode tip with a few drops of the solution to be tested, before taking measurements.

STORAGE

To minimize clogging and assure a quick response time, the glass bulb and the junction should be kept moist and not allowed to dry out.

Replace the solution in the protective cap with a few drops of HI 70300 Storage Solu- tion or, in its absence, Filling Solution (HI7071 for single junction or HI7082 for double junction electrodes).

AmpHel® is a registered Trademark of "Hanna Instruments"

Follow the Preparation Procedure above before taking measurements.

Note: NEVER STORE THE ELECTRODE IN

DISTILLED WATER OR DRY.

PERIODIC MAINTENANCE

Inspect the electrode and the cable. The cable used for the connection to the meter must be intact and there must be no points of broken insulation on the cable or cracks on the electrode stem or bulb.

Connectors must be perfectly clean and dry. If any scratches or cracks are present, replace the electrode. Rinse off any salt deposits with water.

For refillable electrodes:

Refill the electrode with fresh electrolyte (HI7071 for single junction or HI7082 for double junction electrodes). Allow the electrode to stand upright for 1 hour.

Follow the Storage Procedure above.

CLEANING PROCEDURE

General Soak in Hanna HI7061 General

Cleaning Solution for approxi-

mately 1 hour.

Removal of films, dirt or deposits on the membrane/junction:

Protein Soak in Hanna HI7073 Protein

Cleaning Solution for 15 min-

utes.

Inorganic Soak in Hanna HI7074 Inor-

ganic Cleaning Solution for 15

minutes.

Oil/grease Rinse with Hanna HI7077 Oil

and Fat Cleaning Solution.

IMPORTANT: After performing any of the cleaning procedures rinse the electrode thoroughly with distilled water, drain and refill the reference chamber with fresh electrolyte, (not necessary for GEL filled electrodes) and soak the electrode in HI 70300 or HI 80300 Stor- age Solution for at least 1 hour before taking measurements.

TROUBLESHOOTING

Evaluate your electrode performance based on the following.

• Noise (Readings fluctuate up and down) could be due to:

- Clogged/Dirty Junction: Refer to the

Cleaning Procedure above.

- Loss of shielding due to low electrolyte

level (in refillable electrodes only): refill with HI7071 for single junction or HI7082 for double junction electrodes.

• Dry Membrane/Junction: Soak in Storage Solution HI70300 for at least 1 hour.

• Drifting: Soak the electrode tip in warm

Hanna Solution HI7082 for one hour and rinse tip with distilled water. Refill with fresh HI7071 for single junction electrodes and HI7082 for double junction electrodes.

• Low Slope: Refer to the cleaning procedure above.

• No Slope: Check the electrode for cracks in glass stem or bulb (replace the electrode if cracks are found).

• Slow Response/Excessive Drift: Soak the tip in Hanna Solution HI7061 for 30 minutes, rinse thoroughly in distilled water

and then follow the Cleaning Procedure above.

• For ORP Electrodes: polish the metal tip with a light abrasive paper (paying attention not to scratch the surface) and wash thoroughly with water.

MEDIUM DISTANCE, INDOOR/OUTDOOR INSTALLATION

When an outdoor installation is required, it is necessary to install a transmitter to obtain accurate readings at distances from 10 to 50m (33-165').

Since the introduction of AmpHel® these distances are no longer a problem. You are now able to connect your meter directly to an AmpHel® electrode, saving the cost of a transmitter or costly coaxial cable.

The standard cable length of the AmpHel electrode is 5 m (16.5'). Additional lengths of regular cable up to 50 m (165'), can be

installed without special connectors.
