Water activity & pH TEsting

Food or beverage entrepreneur? Your local health department may require the water activity and pH to be tested.  We can help!

What is water activity?  Water activity (Aw) is a measure of the amount of water in a substance that is available for things like microbial growth.  Water activity of a product is between 0 and 1, with pure water having a water activity value of 1.  The lower the number, the less likely for microbial growth.  A value of 0.85 or below indicates the product is not habitable for microbial activity.

What is pH?  pH measures how acidic or basic a solution or substance is.  pH can range from 0 (very acidic) to 14 (very basic) with 7 being neutral.  pH between 0 and 4.6 is not suitable for microbial growth.
