Hydrion® Lo Ion pH Test Kits
Standard pH paper cannot accurately measure the pH of some solutions because the concentration of dissolved ions is too low. For these samples, use a Lo Ion pH Test Kit. Place a 3" strip of paper in the 4-mL test tube, fill with sample, cap, and shake. After 1 min, compare the strip’s color to the supplied color chart. Materials are sufficient for 60 tests. Each kit includes 15-ft roll of paper, test tube with cap, and color chart, all in 1 container.
