Why Water Activity Matters?

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 microorganisims.

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.

This analyser is designed to measure the water activity of food. Whenever and wherever you need to measure water activity, this analyser is the ideal choice. It is a real portable water activity analyser, weighing just 387 grams and offering an accuracy of 0.01 aw, allowing you to measure water activity easily, anytime and anywhere.
