Portable Laboratory Water Activity Meter Kit

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. This 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. Just fill the material into the activity of water measuring chamber and close it.

After an appropriate conditioning time (time period until a constant climate in the chamber is reached = moisture equilibrium) 

the water activity can directly be read off the display of  the humimeter RH2 water activity meter.

The time period until reaching the moisture equilibrium strongly depends on the material to be measured as well as on the temperature. Hygroscopic materials like cornflakes assimilate in a considerably shorter time than whole maize grains. In this context it is important that the samples have the same temperature than the measuring instrument resp. the measuring chamber – high temperature differences lead to a longer conditioning time.

This conditioning time depending on the material is a physical phenomenon and cannot be shortened artificially.

Generally, the conditioning time ranges from 5 minutes to about an hour.

The moisture equilibrium is achieved when the displayed measuring value is no longer changing for a period of several minutes (e.g. 10 minutes, changes less than 0.002 aw).
