Seven important factors for monitoring incoming water supplies, break, suds and bleach operations; also rinse and sour operations. The pH (alkaline) test uses a LaMotte Octa-Slide 2 Comparator. The alkalinity tests, chlorine bleach and hardness test utilize dropper pipet test methods. Reagents are supplied for 50 tests of each factor. Test Factor Range Application pH (Alkaline) pH 10.0-11.4 Break-suds-bleach solutions pH (Sour) pH 1.5-8.5 Sour rinse solutions Alkalinity (Suds) 100 ppm/drop Free/total alkalinity in break-suds-bleach solutions Alkalinity (Rinse) 10 ppm/drop Total alkalinity in rinses Chlorine Bleach 0.5%/drop Available chlorine in bleach solutions Hardness 10 ppm or 1 gpg/drop Water Supply Turbidity Yes/No (Soil) Presence of soil in solution
