This pH indicator strip is type CF. Individual plastic support strips carry four different segments of dye-impregnated 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 be leached into solution. Problems associated with contamination of the sample and resultant anomalous readings are avoided. The convenience of using indicator papers for the rapid determination of pH values has led to many applications in laboratories and industry. Provides instant pH readings. Is accurate for a wide range of routine pH testing. Inexpensive, convenient, and portable for field use. Type: CF. Range: 4.5 to 10.0. Dimensions: 6 x 80 mm.
