Specification BatteriesRequired : 1 Brand : HFBTE BulletPoint1 : (1)Stainless steel sensor,make measurement results more accurate. After the measurement is over, it is more convenient to clean and save. BulletPoint2 : (2)This is a real portable water activity meter lighter than a mobile phone and with precision of 0.02 aw, easy to measure water activity anytime and anywhere. Easy reading, water activity and temperature of the samples displayed together. BulletPoint3 : (3)Fast testing, measures the water activity in 5 minutes. Sensors and readings are integrated. Put the samples in sample boxes and meters are placed on them until the data are stable. BulletPoint4 : (4)Water Activity Meter 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. BulletPoint5 : (5)[If you want to verify the accurate, you can make the standard salt solution by the following steps: ]1. 100g pure NaCl, add into 200g hot distilled water, stir it. Then wait till to room temperature. 2. Keep the solution into a brown bottle for one week in room temperature. 3. In room temperature 25°C (77°F), make sure the meter, solution, room temperature all same temperature. The solution AW value should be 0.73~0.77.
