All together, you‘ll be able to test up to 390 times.

Parameter measuring range precision of method
(value of precision R²)*
Ammonia (NH4+) 0 - 2,0 mg/L 0,998
Nitrite (NO2-) 0 - 1,0 mg/L 0,999
Nitrate (NO3-) 6 - 120 mg/L 0,998
pH-value 6,0 - 9,0 0,970
Chlorine (Cl2) 0,1 - 1,6 mg/L 0,999
Phosphate (PO43-) 0,01 - 1,5 mg/L 0,999
Silicon (Si) 0,05 - 1,0 mg/L 0,998
Copper (Cu2+) 0,02 - 3,0 mg/L 0,999
Iron (Fe) 0,1 – 10,0 mg/L 0,999
Fluoride (F-) 0,1 – 1,0 mg/L 0,983
Oxygen (O2) 2,5 – 18,0 mg/L 0,997

R² is a statistic unit between 0 and 1.The closer the from 0 starting value is to 1, the more precise is the test.
Example: When R2 equals 0.98, the test is 98% precise.
