Available from Paul N. Gardner Co., Inc. (GARDCO), the ExStik(TM) is currently available for use in any medium. The unit's flat surface electrode allows on-the-spot pH measurements of liquid, semi-solid or solid samples, and its "smart chip" eliminates guesswork and tells users when to recalibrate and replace the electrode. A tri-display includes a bar graph showing continuous change in acidity or alkalinity. The unit measures pH from 0.00 to 14.00, with 0.01 pH resolution and accuracy.
