Product Information/Analytical Methods - Field Measurement of Hydrogen Peroxide (1-1,000 mg/L)

PRODUCT INFORMATION

field measurement of hydrogen peroxide (1-1,000 mg/L) analytical methods
miscellaneous test strips and kits

The table below lists several easy-to-use products for measuring H2O2 residuals in the field. The more appropriate selection will depend on a number of factors including the concentration of H2O2 expected, the potential for interfering substances in the water, and the frequency of analysis. Note that the upper limit of each detection range is somewhat artificial, since higher concentrations of H2O2 may be determined by diluting the sample.
