pH Indicator Strips type CF (color bonded dye system)
Individual plastic support strips carry four different segments of dyeimpregnated pH indicator papers. The resulting combination of color differences gives an extremely clear and accurate visual pH value. All the dyes are chemically bonded to the paper and cannot leach into solution, avoiding sample contamination and resultant anomalous pH readings.
pH Indicator Strips type CS (integral comparison chart)
Each pH test strip has a central segment of indicator dye and, printed alongside, eight or more different color segments marked with corresponding pH values for matching purposes.
The pH test value can be read by direct comparison of the pH test strip color against the integrated color bars. pH indicator strips with integrated comparison bars are excellent for colored solutions so that any changes in the color of the paper stock are automatically disregarded.
pH Indicator Strip Dispensers type TC (triple color band)
The pH test strip has three separate indicator dye color bands. It comes as a roll in a convenient dispenser that helps to protect the indicator paper from fumes or aerosols that may change the color of the paper. The individual combination of color change resulting from each test is compared with the colorcoded comparison chart printed on the dispenser for fast and accurate pH testing.
