USER MANUAL

PORTABLE pH METER

MODEL: MW101

Smart pH Meter

OPERATION:

• The meter is supplied complete with a 9V

battery. Slide off the battery compartment

cover on the back of the meter. Install the

battery into the battery clip connector while

observing polarity.

• Always remove the electrode protective

cap before taking any measurement. If

the electrode has been left dry, soak the

tip (bottom 2.5 cm) in rinse solution

(M10000B) for a few minutes to reactivate

it.

• Connect the pH electrode

to the BNC socket on

the top of the meter.

• Turn the instrument on

by pressing the ON/OFF

key.

• Make sure that the meter has been

calibrated before taking any measurements

(see Calibration Procedure).

• Set the temperature knob

to the value of testing

solution (measured

with help of an accurate

thermometer).

• Immerse the tip (2.5 cm)

of the pH electrode into

the sample and stir

gently.

• After completing measurements,

switch the meter off and store

the electrode with a few drops

of storage solution (MA9015)

in the protective cap.

CALIBRATION PROCEDURE:

A) Preparation:

Two calibration buffers are required

1. pH 7.01 (MA9007)

2. pH 4.01 (MA9004) if you are measuring

in acid range (pH 0 - pH 7) or pH 10.01

(MA9010) if you are measuring in

alkaline range (pH 7 - pH 14).

Use two beakers for each pH buffer. One

beaker for rinsing the electrode, the other

for calibration.

Use a thermometer with 1ºC accuracy to

measure the temperature of calibration

solution.

B) Procedure:

• Remove the protective cap

from the electrode. Rinse

the tip of the electrode with

some pH 7.01 solution, then

immerse the pH electrode

into a pH 7.01 buffer solution.

• Take the temperature of

the buffer solution with a

thermometer and set the

temperature knob to the

measured temperature (e.g.

15ºC).

• Adjust the OFFSET trimmer

(pH 7) on the front panel, with

a small screwdriver until the

LCD shows the pH value at

temperature of the buffer (see

the pH versus temperature

chart).

E.g. in this case, if the

temperature is 15ºC, the

meter display should be

adjusted to read “pH 7.04”.

• Now rinse the pH electrode

in the first pH 4.01 beaker,

then immerse it into the

second pH 4.01 beaker or

follow the same procedure

if using pH 10.01 buffer.
