The moisture meter is a portable measuring device for water activity. Water activity indicates the amount of water that is biologically available for microorganisms such as bacteria, fungi, or similar. Each type of microorganism has a minimum water activity value below which no growth is possible. The higher the aw value of a food, the more perishable it is. Bacteria typically require a water activity of over 0.98, but significantly lower water activity of up to 0.6 can be tolerated by extremely halophilic bacteria, for example. The moisture meter has a measurement range of 0.01 aw to 1 aw with high accuracy of ±0.03 aw. The measuring attachment is magnetic, ensuring that the sample can be measured securely and protected from light. The moisture meter comes with 3 sample trays, allowing many food items to be quickly tested for shelf life. Additionally, 2 AAA 1.5V batteries are required to operate the moisture analyzer. It is used in the food industry, for water activity analysis in laboratories, seed storage, and other fields.
