Date of testing: pH, Color, Turbidity, Total hardness, PO43-, Total PO43-, Organic phosphines, Total alkalinity, OH-, CO32-, HCO3-, Cl-, Free chlorine. Units: F·T·U, milligrams/liter, milligrams/liter, milligrams/liter, milligrams/liter, milligrams/liter, millimoles/liter, milligrams/liter, milligrams/liter. Target values: 8.0–9.2, ≤14–6, >3100–500, ≤300, 0.5–1.0. Test date: 20120215; Values: 8.89, 131.21, 476, 1.2, 9.1, 7.9, 255, 0.00, 1.64, 3.46, 191.1
Add more 509 so that the laboratory technicians can conduct more tests and observe the patterns of change
The parameters for circulating water are generally as follows: conductivity: less than 3600; pH: 6.8------9.5; total iron: less than 1; chloride ions: less than 450; calcium ions: less than 200; magnesium ions； Total alkalinity: less than 150; Concentration ratio: 3---5
“Add more – what is 509 in 509”? Please let me know
