- pH (at 25 C) *
- Conductivity (µS/cm) at 25 C *
- Total Dissolved Solids (ppm as NaCl)
- Total Hardness (ppm as CaCO3)
- Ca-Hardness (ppm as CaCO3)
- Mg-Hardness (ppm as CaCO3)
- M-Alkalinity (ppm as CaCO3)
- P-Alkalinity (ppm as CaCO3)
- Bicarbonate (ppm as CaCO3)
- Total Iron (ppm as Fe)
- Chloride (ppm as Cl)
- Residual Chlorine (ppm as Cl2) at site checking
