Water Activity - Moisture Meter

icon

The measurement of water activity or equilibrium relative humidity is a key parameter in the quality control of moisture-sensitive products or materials. Water activity is by definition the free or non chemically bound water in foods and other products. The bound water cannot be measured with this method.

ROTRONIC offers fast and accurate instruments for the measurement of water activity of foods, seeds, pharmaceuticals, cosmetics, etc. ROTRONIC unique technology guarantees water activity measurement at the lowest possible purchase price.

Choose from 3 different water activity systems to match your particular application. All systems use the high precision technology to ensure precise and accurate results in addition to full interchangeability between the quality control laboratory and production areas. The water activity probes measure product samples, bulk materials and can be used to test product packaging.
