Ultra-compact water activity meter

April 4, 2003




The new portable Pawkit water activity system is self-contained and battery-operated. The Pawkit is 4 inches long and weighs only 4 ounces, with an accuracy of I0.02 aw. Until now, portable quick water activity checks by health inspectors and food scientists didn't exist. Now, however, they can bring the lab with them, and with easy calibration, they save time and money. Water activity affects the ability of microorganisms to proliferate in foods. Therefore, monitoring water activity is a critical control point for many manufacturers. Incorporating water activity testing and other science-based analyses into a food safety program helps ensure the highest quality and safest food supply.
