J-pHix® pH tests are useful for testing aqueous solutions in environmental analysis and in industrial in-process controls. Johnson Test Papers’ J-pHix® pH indicator strips offer significant advantages over other pH test strips due to the unique way in which they are manufactured. The sample will not be contaminated if the pH indicator strip is left in there because the pH indicator dye does not bleed. This simple semi-quantitative method can determine the pH value by visual comparison of the reaction pad against the colour chart. The colour is accurately printed for each batch produced. A clear plastic case allows for safe storage and easy removal of strips. Recommended to provide an indication or pre-testing of pH values before further investigation.
Remove one of Universal Indicator strips from the pack, being careful not to touch the strip anywhere other than the plastic. Dip the strip into the solution you are testing for around 1-2 seconds and remove. The strip will then change colour, you should compare this colour against the pack’s colour chart in order to give a pH reading.
