Description
The water activity meter mainly reflects the amount of free water in the food equilibrium state, the stability of the food and the possibility of microbial reproduction, and the chemical, enzymatic and physical changes that can cause the change in food quality. It is often used to measure the dryness resistance capacity of microorganisms. By measuring the water activity of food and selecting reasonable packaging and storage methods, the use of preservatives can be reduced and the shelf life of food, cereals, and fruits and vegetables can be judged.
The machine can be used to measure the water activity of food. No matter when and where you need to measure water activity, the machine water activity meter is your unique choice. This is a real portable water activity meter, weighing only 100 grams, lighter than a mobile phone and an accuracy of 0.02 aw, easy to measure water activity anytime and anywhere.
The activity meter can measure bread, cookies, cakes, puffed foods, snacks, dried foods, nuts, clams, canned fruits, etc. It mainly reflects the amount of free water in the food equilibrium state, the stability of food. and the possibility of microbial reproduction, and the chemical, enzymatic and physical changes that can cause the change in food quality. It is often used to measure the dryness resistance capacity of microorganisms.
