Short-range Lo-Ion pH paper in the range of 3 to 6. The Lo-Ion test kit gives you true pH values for raw water and ion exchange waters. You can measure the pH of all dilute solutions - even neutral salt solutions, without investing in special equipment or expensive laboratory facilities. These kits consist of a dispenser of Lo Ion Test Paper, instructions for testing unbuffered solutions, a sample tube with cap and a color comparator chart coated to protect it from wear and exposure. This Lo-Ion paper has a distinct color change for each half pH from 3 to 6. Estimates can be made to 0.25 pH. (Wide Range kits have well defined colors for each pH and estimates can be made to one half pH).
Single 15-foot roll in a dispenser with one color chart as shown to the left. Is contained in a plastic case with an additional chart. That case, a stoppered clear plastic tube and instructions are contained in another, slightly larger plastic case.
