Total Alkalinity and pH test scales
# 115 pH and TOTAL ALKALINITY of Water
Colorimetric test strips. (2 tests per strip)
pH and Total Alkalinity are two of the most fundamental parameters in drinking water testing as well as a great variety of other applications of water usage. Alkalinity indicates the buffering capacity of natural waters. A water is buffered if the pH does not change greatly by addition of acids or bases.
The most effective buffering action is within the pH range of water from 6.0 to about 8.5. The productivities of water can be correlated with ph, alkalinity and the buffering system.
The color charts for these tests read pH levels and Total Alkalinity in mg/L or ppm.
The Color Comparator Chart test reports levels of:
pH levels of 6.0, 6.5, 7.0, 7.5, 8.0, 8.5, 11
Total Alkalinity 0, 40, 80, 120, 180, 240, 720 mg/L or ppm.
Both tests are on the same test strip.
Results are obtained from this test in 25 seconds.
QuickCheck science fair water test kits allow the student scientist to perform semiquantitative tests on water samples at home, school or outdoors. These Science Fair test kits include clean, sterile water sample bags and test strip instructions and color concentration comparator that make each kit very convenient and simple to use.
