Topac introduces the FAST1 water activity monitor. The FAST1 is a water activity meter for quality control and research applications of the water activity of food and pharmaceutical products.
Water activity indicates how tightly water is bound in a product.
It is a direct measurement of the active or 'free' water in a product that is available to participate in the chemical reactions that promote spoilage and bacterial growth. The FAST1 uses chilled dew point technology to measure water activity. This fast technique involves the measurement of the relative humidity in an enclosed chamber that contains a sample of the product being studied. A unique feature of the FAST1 is the measuring chamber, which is a sealed chamber independent of the sample cup, designed to prevent contamination of the seal by the sample. The FAST1 is supplied ready to use with instructions, keyboard, and sample cups.
