pH Indicator Papers and Test Strips
The pH indicator strips measure phosphate content levels through rapid colorimetric reactions. Narrow, intermediate, or universal range options are ready for immediate quantitative testing and feature different graduated intervals for accurate assessments. After immersing pH indicator strips in solutions and samples, simply match the produced color with the charts provided. Compact litmus paper tests can be carried in the field for on-site testing in addition to testing in the laboratory.

BDH® pH Test Strips
Supplier: BDH
Used for rapid pH testing directly at the point of interest, strips are always ready for immediate use. They are also suitable for careful testing of dangerous, poisonous, or aggressive liquids as the long handle prevents fingers from coming into contact with the sample. The dye is chemically bound to the test strip and cannot bleed into the sample, protecting against contamination and enabling measurement in weakly buffered or strongly alkaline solutions. Included color chart has 4 different color blocks for each pH value, enabling highly precise pH determination. Strips are available in 13 different pH ranges with accuracy down to 0.2 pH units. Dimensions: 85Lx6Wmm.
