Bante Instruments PHscan10 User manual

Bante is committed to the reduction and eventual elimination of all hazardous
substances in both the manufacturing process and finished products we supply.
We have an active manufacturing and procurement program to minimize and
eliminate the use of harmful heavy metals such as cadmium, lead, mercury and
the like.
New technologies and design parameters are also promoting these efforts and
we expect to have little or no such materials in our product in the coming years.
We welcome our customers suggestions on how to speed up these efforts.

Introduction
Thank you for selecting the PHscan10 pocket pH tester. This manual provides
a step-by-step guide to help you operate the meter, please carefully read the
following instructions before use.
Inserting the Batteries
insert batteries into the battery compartment.
— Remove the battery compartment lid.
— Insert the batteries into the battery compartment, note polarity.
— Replace the battery compartment lid and turn clockwise until it is tight.
Keypad
PHscan10 tester includes 3 multifunction keys, names and symbols describe
the function key controls.
Take out the three G13A button cell batteries from the packaging. Follow the
steps below to
— Power the tester ON/OFF.
— Freezes the measured values on the display, press the
key again to resume measuring.
— In calibration mode, exits calibration and returns to
measurement mode.
— Press and hold the key to enter calibration mode.
— Press the key again to select the pH buffer option.
— Confirms the calibration or option.

Preparation of pH Standard Buffer Solutions
The tester is packaged with three pH buffer packets required for calibration.
Open the pH7.00 buffer packet, place the powder into a 250ml volumetric
flask. Pour distilled water 250ml to scale line, mix the solution until reagent
is completely dissolved.
Preparation of pH4.01 and 10.01 standard buffer solutions are the same as
above. Prepared standard buffer solutions should be stored in hermetically
sealed glass containers.

Choose the pH buffer option you want to use, press ENTER key to confirm.
The tester shows first calibration point, pH7.00.
4. Dip the electrode into the pH7.00 standard buffer solution, the end of the
electrode must be completely immersed into the calibration solution. Stir
the tester gently.
Power On/Off
Press and hold the MEAS key for 5 seconds, the tester will turn off.
you do not press any key for 8 minutes, the tester will automatically turn
off to conserve energy.
Calibration
The tester must be calibrated prior to first use or new electrode replaced.
To ensure accuracy, regular calibration is recommended.
Do not reuse calibration solution after calibration, contaminants in solution
will affect the calibration and eventually the accuracy of the measurement.

Electrode Replacement
When the tester fails to calibrate or gives fluctuating readings for calibration
standards, you need to replace the electrode module.
1. Twist the electrode collar counter clockwise, pull the old electrode module
away from the tester.
2. Align the slot on the new electrode module, gently push the module into the
tester.
3. Twist the electrode collar clockwise until it is tight.
1. press MEAS key to turn
on the tester.
2. Dip the electrode into the sample solution, stir the tester gently.
3. W reading the measured value on the display.
Hold Function
1. During the measurement, press HOLD key,
, “HOLD” indicator appears on the display.
2. Press the key again to release the measured reading, you can continue to
take measurement.
Electrode Care and Maintenance
— For best results, please always keep the sensor’s glass bulb wet.
— Ensure that the sensor is thoroughly washed with distilled water after each
use.
— If you do not use the tester for long periods, please store the sensor with
electrode storage solution. DO NOT use de-ionized or distilled water.
Installation is completed.

Troubleshooting
— Electrode dried out.
Soak the electrode in tap water for 10 minutes.
— Measured value is out of range.
Check the electrode whether clogged, dirty or broken.

— Incorrect buffer used or contaminated buffer solution.
Use fresh pH buffer solutions for calibration.
— Electrode is broken.
