separate test pads: one for pH and the other
for Total Alkalinity measurements. This test is an
alternative to wet chemical tests since it gives reproducible results for each test separately. Test range is from 6.0 to 9.0 for pH and 0-360 ppm (mg/L) for total alkalinity.
To use, dip one test strip into a water sample for 10 seconds then remove. Immediately match the pH test pad color, then match the total alkalinity test pad color. There are no chemicals to mix, results are obtained in 30 seconds, and the test strips are safe to use with no hazardous chemicals (no MSDS required).
