A new generation of water activity detectors listed on the crown moisture meter manufacturing
Definition of water activity:
Water Activity (abbreviated as aw) mainly reflects the amount of free water in the food equilibrium state, the stability of the reaction food and the possibility of microbial reproduction, as well as the chemical, enzymatic and physical changes that can cause changes in food quality. To measure the ability of microorganisms to endure dryness. By measuring the water activity of the food and selecting a reasonable packaging and storage method, the use of the preservative can be reduced, and the shelf life of food, grain, fruits and vegetables can be judged.
Guanya GYW series feed water activity detector pricing / price and working principle :
  Guanya GYW series feed water activity detector is a machine for detecting the content of water molecules. It mainly reflects the effective moisture in the equilibrium state of food, the stability of food reaction and the possibility of microbial reproduction, and can cause changes in food quality. The chemical, enzymatic, and physical changes are often used to measure the ability of a microorganism to endure dryness. Widely used in the pharmaceutical production industry, professional testing institutions, food hygiene supervision departments to provide complete water activity measurement programs, as well as dehydrated food processing, dried meat products processing, powdered food raw material production, food additives and canned foods in food production plants. Production and Other fields. Guanya GYW feed water activity detector mainly includes water content detector, water activity measuring instrument, bench water activity analyzer and so on. The water activity analyzer adopts imported high-precision sensor, professional circuit design, stable and reliable work; reasonable structure design, easy operation, solving the problem of inconvenient operation and easy liquid turning; the calibration and measurement time only takes 10 minutes. One calibration, no need to repeat calibration in a long period of time; using high-brightness liquid crystal display, Chinese characters display, more content; with printing function, more convenient to record and compare. ,
