FAST AND PRECISE WATER ACTIVITY MEASUREMENTS.INTRODUCING AIRCHIP DIGITAL TECHNOLOGY.
WATER ACTIVITY MEASUREMENT
WATER ACTIVITY
ROTRONIC offers a complete range of water activity products. Use any combination of probes to fit your application.
ROTRONIC products are freely combinable and can be perfectly adapted to your needs. The devices are accurate and
are characterized by their high efficiency, exchangeability, and ease of calibration.
BE PRECISE:ADVANTAGES AT A GLANCE.
What is water activity?Wateractivity,bydefinition,isthemeasurementofwater
vaporpressuregeneratedby the freeornon-chemically
bound water in foods and other products. The bound
waterandmoisturecontentcannotbemeasureddirectly
withthismethod.TheAwvalue(range:0.00...1.00aw)is
animportantindicatorfortheshelflifeoffoods,pharma-
ceuticalandcosmeticproductsanditstronglyinfluences
theoccurrenceandgrowthofmicroorganisms.

What is water content?Watercontent,whenreferring toasolidmaterial, isanexpressionof thepercentageof thematerialsweightwhich iswater (both in liquidor

Water activity or water content?There is frequently confusion between water activity and water content
measurements. In many industries, water content is used to control the
amountofwaterpresentinaproductforquantitativereasons.Forexample,
ifaproduct issoldbyweight,controlling itswatercontentmaybeuseful
in maintaining product quality, but can also impact on profitability (more
waterequalsmoreprofit).Wateractivity ismoresignificant forqualitative
considerations such as product stability, shelf life (e.g. microbiological &
enzymaticstability,aroma retention),handlingcharacteristics (e.g.agglo-
meration of powders), physical properties (e.g. dimensions of paper) and
chemicalstability(e.g.pharmaceuticals).Wateractivityandwatercontent
