BANTE ORPscan10/20 Pocket ORP Tester

Product Overview

Thank you for selecting the ORPscan series pocket ORP tester. This user manual provides a step-by-step guide to help you operatethe tester, please carefully read the following instructions before use.

Product Installing the Batteries

Twist the electrode collar counter clockwise, pull theelectrode (or BNC connector) away from the tester.
Insert two AAA alkaline batteries into the battery compartment, note polarity.

Product Prior to Use

ORPscan10:

Remove the protective cap (and translucent cover) from the bottom of the tester.
If some salt crystals deposited on the electrode, rinse with tap water to clean these deposits.
If the platinum sensor has dried out, soak the electrode in 4MKCl solution for about 30 minutes.
Push the electrode (or BNC connector) into the tester and twistthe electrode collar clockwise until tight.

ORPscan20:

Take out the ORP electrode from carrying case.
Insert the BNC connector into the connector socket on tester, rotate and push the connector clockwise until it locks.

Keypad

Key	Description
measurement	Switches the tester to measurement mode
Cal	Enters the calibration mode or setup menu

Switching the Tester On and Off If the battery voltage falls below the minimum powerrequirements, the icon automatically disappears. If you do not press any key within 8 minutes, the tester will switch off automatically to conserve energy.

The ORPscan10/20 tester contains 3 menu items in the setup menu, the following table describes the functions of each option.

Menu Item	Option and Description
Auto-Hold	If enabled, the tester will automatically sense and lock the

measurement endpoint.
Auto-Power Off| If enabled, the tester will automatically switch off if no key
is pressed within 8 minutes.
Factory Reset| If enabled, all of the calibration values and current settings
will be deleted or reset to the factory defaults.

Setting the Default Option

In the measurement mode, press and hold the Cal key to enterthe setup menu.
If necessary, press the Cal key again to select an option.
Press the Enter key, the tester saves the current option andmoves to the next menu item.
Repeat steps above until the tester returns to the measurement mode.

To exit the setup menu, press the Meas key.

Product Measurement

Rinse the electrode with distilled water.
Place the electrode into the sample solution and stirgently.
Note, DO NOT completely immerse the tester in water.
Wait for the measurement to stabilize and record the reading.

If the sample solution contains chromous, vanadous and titanous ions or other ions that interfere with the ORP measurement range,remove the tester from the sample immediately. If the Auto-Hold option is enabled in the setup menu, the tester will automatically
lock the measurement endpoint and show HOLD icon. Press the Measkey to resume measuring.

Relative mV Calibration The ORPscan10/20 tester allows 1 point calibration, butcalibration is not necessary unless exact readout agreement with a work standard and at a specific ORP value is needed.

Rinse the electrode with distilled water and place into thestandard.

Prior to Use

ORPscan10
Remove the protective cap (and translucent cover) from the bottom of the tester. If some salt crystals deposited on the electrode, rinse withtap water to clean these deposits. If the platinum sensor has dried out, soak the electrode in 4M KCl solution for about 30 minutes

ORPscan20
Take out the ORP electrode from carrying case. Insert the BNC connector into the connector socket on tester, rotate and push the connector clockwise until it locks.

Switching the Tester On and Off

Press and hold the Meas key for about 5 seconds to switch on the tester.
Press and hold the Meas key to switch off the tester.
If you do not press any key within 8 minutes, the tester will switch off automatically to conserve energy.

The ORPscan10/20 tester contains 3 menu items in the setup menu, the following table describes the functions of each option. BANTE-ORPscan10-20-Pocket-ORP-
Tester-FIG 10

Setting the Default Option

In the measurement mode, press and hold the Cal key to enter the setup menu.
If necessary, press the Cal key again to select an option
Press the Enter key, the tester saves the current option and moves to the next menu item.
Repeat steps above until the tester returns to the measurement mode.
- To exit the setup menu, press the Meas key.

Measurement

Rinse the electrode with distilled water, place the electrode into the sample solution and stir gently. Note, DO NOT completely immerse the tester in water. Wait for the measurement to stabilize and record the reading.

The platinum sensor may give unstable readings in solutions that contain chromous, vanadous and titanous ions or other ions that are stronger reducing agents than hydrogen or platinum.
If the display shows —- indicating the measurement exceeds the range, remove the tester from the sample immediately.
If the option is enabled in the setup menu, the tester will automatically lock the measurement endpoint and show HOLD icon. Press the Meas key to resume measuring.

Relative mV Calibration

The ORPscan10/20 tester allows 1 point calibration, but calibration is not necessary unless exact readout agreement with a work standard and at a specific ORP value is needed.

Rinse the electrode with distilled water and place into the standardsolution. Stir the tester (or electrode) gently and wait until the measurement is stable.
Press the Cal key, the display shows 000/CAL.
Press the Cal key again to modify the calibration value, press the Enter key to confirm and move to the next digit. When the setting is completed, make sure that the displayed value matches your calibration standard.
Press the Enter key, the tester begins the calibration. When the reading has stabilized, the display will show .

After the calibration, the measurement unit “mV” will automatically convert to “R.mV” (relative millivolt). If you want to resume the mV measurement, reset the tester (refer to the Setup Menu section).
To exit the calibration without saving calibrated value, press the Meas key.

Electrode Maintenance

Rinse the electrode thoroughly with distilled water after use.
In the corrosive chemicals, viscous solutions and solutions with heavy metals or proteins, take readings quickly and rinse electrode immediately.
If you do not use the tester for a period longer than 1 month, store the electrode in 4M KCl solution or electrode storage solution.

Appendix

Preparation of ORP Standard Solutions
Quinhydrone solution A:
Dissolve 3 grams of quinhydrone reagent in 500 ml of the pH 4.01 buffer solution, stir the solution for about 10 minutes. Undissolved quinhydrone reagent must be present. If necessary, add the reagent.

Temperature	Quinhydrone in pH 7.00 (±10 mV)
20°C (68°F)	94 mV
25°C (77°F)	87 mV
30°C (86°F)	80 mV

Quinhydrone solution B:
Dissolve 3 grams of quinhydrone reagent in 500 ml of the pH 7.00 buffer solution, stir the solution for about 10 minutes. Undissolved quinhydrone reagent must be present. If necessary, add the reagent.

Temperature	Quinhydrone in pH 4.01 (±10 mV)
20°C (68°F)	268 mV
25°C (77°F)	263 mV
30°C (86°F)	260 mV

Due to the quinhydrone solution is susceptible to air oxidation in storage, make sure to prepare the fresh solution before use.

Preparation of Electrode Storage Solution
Dissolve 29.82 grams of analytical grade KCl reagent in 100 ml distilled water. Add pH 4.01 standard buffer and adjust solution to pH 4.
