A method and apparatus (20) for gauging the levels of pH in the interiors of articles such as diapers (12), incontinence garments, pads, catamenial products, bedding, and wound dressings. The method and apparatus include sensing devices (16, 29, 37, 41) and relay systems (38, 47) for displaying the pH on the outside of the articles that provide visual or audible warnings that deleterious levels of bacteria and compounds are building up in the absorbent article and that the aricle should be removed and replaced. |
