This is a Portable Water Activity Meter, with a Weight of Onlyġ00g, Lighter than a Mobile Phone & a Precision of 0.A Water Activity of 0.80 means that the vapor pressure of the food is 80% that of pure water. The measurement of water activity or equilibrium relative humidity is a key parameter in the quality control of moisture-sensitive products or materials. It is actually a ratio between the vapor pressure of the food itself when in a completely undisturbed balance with the surrounding air media & the vapor pressure of distilled water under identical conditions. This type of measurement is also a good indicator of when the product is ready for packaging. It equals the relative humidity of air, in equilibration with a sample, in a sealed measurement chamber (commonly known as equilibrium relative humidity, or ERH). Waterlab is the most performing instrument on the market thanks to its dew point sensor which measures the actual water activity (aW) and not related and. These are Resistive Electrolytic Hygrometers (REH), Capacitance Hygrometers, and Dew Point Hygrometers. Manufactures of food & pharmaceutical products measure water activity to show when the water activity of their product has declined to a point where bacteria can no longer grow. There are three basic water activity measurement systems. This can lead to clumping, changes in consistency & reduced shelf life. The HygroPalm 23-AW-A is ideal for measuring water activity in production processes such as random checks of cheese, meat, tobacco, building materials, animal. Speed and Accuracy Measure water activity in 5. If there is “too much” water in a food product, there is a risk of microbial growth & water migration. The METER AquaLab 4TE water activity instrument is the leader in benchtop water activity instrumentation. Water activity, or aw, is a measure of the free moisture in a product and is defined as the ratio of vapor pressure of a substance to that of pure water at.
