water activity meter / analyzer - humimeter RH2
Portable laboratory instrument for determination of water activity (aw value)  - MESSTECHNIK SCHALLER GMBH


The water activity of products, especially of food, indicates the amount of unbound water in a material. This quality factor, also called aw value, depends on the water vapour pressure in the material, on the current temperature and on the water vapour pressure of the surroundings. The humimeter RH2 water activity meter enables the quick and easy determination of the water activity. Furthermore, due to the large sample volume of the water activity measuring chamber, higher quantities can be measured within a short time, enables a higher number of taken random samples. The simple handling guarantees a cost-saving and faultless process of measuring the activity of water value of food. + Relative humidity, absolute humidity, dew point, equilibrium moisture content, aw-value + Long stable humidity sensor + Easy data storage at the portable moisture meter + Analysis on the PC and printer available + Optimal documentation of your quality
