Schaller humimeter RH2-AW Water Activity Meter
with aw-value measuring cell set


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.

The measuring cell (code 14500) offers a small sample volume and inserts made of plastic. A much smaller sample volume is required here and can therefore be filled with crushed and ground samples or also with liquids such as sauces and pastes. The plastic vessels must be almost completely filled in order to achieve a good measurement result and rapid adjustment behavior. After the measurement, they can be easily exchanged or cleaned.
It is important that the sensor is not exposed to acids, bases, solvents or excessive salt concentrations!
