The pH 0-7 test strips feature three pads for enhanced accuracy. They measure in 0.5 pH increments and provide results in seconds, covering the full acid range from pH 0.0 to neutral pH 7.0.

When comparing to the color chart, the closest match of all three is the correct value. Only one or two of the three pads will change for any given acid.

Specifications:

• Test Range: pH 0-7
• Test Increments: Color charts calibrated at 0.5 increments from 0 to 7
• Accuracy: +/- ½ color chart unit (+/- 0.25 pH units)
• Storage: Store in original packaging in a cool (20-30C), dry, place out of direct sunlight.
• Shelf Life: 18-24 Months
  

Instructions:

1. Remove one pH 0-7.0 test strip by holding between your index finger and thumb. Do not touch the test pad with your finger.
2. Dip the test strip into the solution to be tested so that all three pads are completely immersed.
3. Remove the test strip, and shake off any excess liquid.
4. Compare to the color chart within 30 seconds. Do not allow the test strip to dry before reading against the color chart.
