AWTherm Water Activity Meter
High-end laboratory unit for temperature-stabilized measurement of water activity in the foodstuffs, cosmetics, or pharmaceutical industries
The AwTherm from Rotronic is a high-end laboratory instrument for water activity measurements in the food, cosmetics and pharmaceutical industries. The significant advantage of the AwTherm lies in the possibility to heat or cool the measurement chamber, which simplifies and optimizes the measurement process considerably in the case of tempered products, be they goods in cold storage or on heated conveyor belts.
