RH2 Water activity meter analyzer

Model RH2

Manufacturer: Schaller Messtechnik

– Portable laboratory instrument for determination of water activity (aw value) of food with datalog function.

– Suitable for measuring materials like butter, fruit mix, spices, granulate, mushrooms, xylit, flour, biscuits, or sausage as well as all other food types requiring a check of the water activity value.

– Furthermore, the Humimeter RH2 is suited for measuring special material, e.g. plastic granulate or for climatic and environmental applications.

– Not suited for juices (syrup), acidic food like vinegar or food and beverages containing alcohol.
