1. APPLICATIONS & FEATURES
*The Water Activity, mainly reflects the
amount of free water in the state of food
balance, the stability of food and the
possibility of microbial reproduction, and
the chemical, enzyme and physical
changes that can cause the change of food
quality. It is often used to measure the
dryness enduring ability of the
microorganisms. By measuring the water
activity of food and selecting reasonable
packing and storage methods, the use of
preservatives can be reduced and the shelf
life of food, grain and fruits and
vegetables can be judged.
*The can be used to measure thePCE-WAM 10
water activity of foods. No matter when
and where you need to measure water
activity, water activity meterPCE-WAM 10
is
your unique choice. This is a real
portable
water activity meter, with a weight of
only 100 grams, lighter than a mobile
phone, and a precision of 0.0 aw, easy to 3
measure water activity anytime and
anywhere.
*Sensors and readings are integrated.
*Easy reading, water activity and
temperature of the samples displayed
together.
*It has automatic shutdown, manual
shutdown function and undervoltage
alarm indication function.
*Use USB data output to connect with PC.
*Provide Bluetooth data output choice.

4. MEASUREMENT PROCEDURE
4.1 Press the power key to switch on the
power and the gauge enters the auto mode
which can automatically test the water
activity.
4.2 Put the samples into the sample plate, and
then cover the sensor of the gauge onto the
sample plate. Lay aside for about 5
minutes, when the reading gets stable, the
water activity can be obtained.
4.3 After testing, press and hold the power key
for about 3 seconds to turn off the gauge.
Clean the sample plate for next use.
5 . READING CORRECTION
5.1 When it is necessary to correct the reading
value, press and hold the Power Key for
about 7 seconds. Then release the key
when the signal ‘Cor’, comes out on the
display. There will be a decimal number
with two places, which is the correction
value.
5.2 Then open the battery cover on the back,
there are 2 small hole below the battery
slot. Use a small hard bar(such as
screwdriver) to slightly touch the key
inside, the correction value will be
increased or decreased. The value
increases when touching the right hole,
while the value decreases when touching
the left hole. Each time the key is touched,
the correction value changes by 0.01. The
correction value can be set from -0.14 to
0.14.
5.3 After the adjustment, press the
Power Key
to quit.
6. BATTERY REPLACEMENT
6.1 When it is necessary to replace the
battery, the battery symbol “ ”
will
appear on the Display.
6.2 Slide the Battery Cover ( Fig.1,) away
from the instrument and remove the
batteries.
6.3 Install the batteries (2x1.5vAAA UM-4)
correctly into the case.
6.4 If the gauge is not to be used for any
extended period, remove batteries.
