PH indicator paper provides a fast and economical method of ph measurement. For most solutions it is only necessary to dip a short strip of test paper in the solution for a second or two. Then shake off the excess fluid and match the color of the wet test paper with its color chart and read off the values.
Features:
1) Wide range paper ph 0-14, resolution is 1 ph unit
2) Colours of the individual colour fields cannot run into each other. This allows a more precise comparison the colour scale.
3) The plastic strips protect fingers from contact with the test solution.
4) Papers are non-bleeding so the test samples are not contaminated by the indicator dyes.
5) Ph range: 0-6, 0-14, 1-14, 1-11, 1-10, 1-12, 4-10, 9-14.
