Overview
AMITTARI WA-160A Water Activity Meter is a Portable device for the measurement of water activity (Aw) of food. Moisture activity mainly reflects the free Moisture content of food in the equilibrated state. It is used to evaluate food Stability, microbial reproduction possibility and quality changes. It helps to choose reasonable Encasement and storage methods, reduce preservative use, and judge the shelf life of food, grain, fruits and vegetables.
Features
1. Sensor and reading integrated design
2. Easy to read, displaying both water activity and sample temperature
3. With automatic shutdown, manual shutdown function and under-voltage alarm indication function
4. Use USB data cable output to communicate with PC
5. Provide Bluetooth data output selection
Principle
The water activity meter measures the water activity value of the sample through the non-conductive Humidity Sensor. During the measurement process, the Response value of the water activity meter is recorded every 5 minutes. When the difference between the two adjacent Response values is less than 0.01Aw, it is the measured value. The fastest Measurement speed is 10 minutes.
Steps
1. Install 2x1.5vAAA AA AA batteries
2. Wait for the instrument to initialize after booting
3. Measuring location of samples
4. The instrument automatically starts the measurement and records the Response value every 5 minutes
5. When the difference between two adjacent Response values is less than 0.01Aw, read the final measured value
6. Data can be output via USB or Bluetooth
Notice
* Temperature range 0~ 50 ℃
* Pay attention to the battery power, replace it in time to avoid undervoltage affecting the measurement
* Avoid moving or interfering with the instrument during the measurement process
* Measurement accuracy calibrated regularly
* Clean Sensor after use
