Six parameters, three taps
Open a visit on the field app and the water-chemistry panel is one tap away. Punch in free chlorine, pH, total alkalinity, calcium hardness, cyanuric acid and salinity if the pool is salt. Enter the values you actually measured and leave unmeasured fields blank. Check each entry before saving it to the visit.
Each reading is timestamped, attached to the visit, and labeled before or after treatment. Compare the arrival readings with the finished treatment, then follow changes between visits.
