  than a mobile phone.

2. How to Use the PCE-WAM 10 Water Activity Meter

1. Ensure the device is powered on and ready for use.

2. Select the sample to be measured and prepare it
   accordingly.

3. Place the sample on the sensor area of the meter.

4. Wait for the readings to stabilize, typically within the
   specified sampling time of up to 10 minutes.

5. Read and record the displayed water activity and temperature
   values.

6. If needed, use the USB or Bluetooth data output to transfer the
   results to a PC or other device for further analysis.

Frequently Asked Questions (FAQ)

Q: Can the PCE-WAM 10 be used for measuring water activity in

non-food samples?

A: While primarily designed for food applications, the water
activity meter can also be used for measuring water activity in
other non-food samples as long as they are compatible with the
sensor.

Q: What is the significance of the undervoltage alarm

indication function?

A: The undervoltage alarm indication function alerts users when
the battery voltage is low, ensuring timely replacement or
recharging to maintain accurate measurements and device
functionality.

WATER ACTIVITY METER PCE-WAM 10

1. APPLICATIONS & FEATURES

• The Water Activity, mainly reflects the amount of free water in the state of food balance, the stabilityof 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.

water activity meter, with a weight of only 100 grams, lighter than a mobile phone, and a precision of 0.03 aw, easy to 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.

• The PCE-WAM 10 can be used to measure the water activity of foods. No matter when and where you need to measure water activity, PCE-WAM 10 water activity meter is your unique choice. This is a real portable
