What is Water Activity?
Water activity (aw) is expressed as the ratio of the vapor pressure in a food (P) to the vapor pressure of pure water (P0). It predicts whether water is likely to move from the food product into the cells of micro-organisms that may be present.
AW-600 is a robust designed Water Activity Analyzer
The AW-600 portable Water Activity Analyzer is designed to accurate measures the vaper pressure of free water escaped from samples to the air in the test chamber to predict the condition of growth of bacteria.
Why do you need a Water Activity Analyzer?
Water activity is a measurement of the availability of water for biological reactions. It determines the ability of micro-organisms to grow. If water activity decreases, micro-organisms with the ability to grow will also decrease.
