AQUA-CHECK 2 is the professional photometer for those who want to find out more. You can detect oxygen, iron and fluoride plus the 7 other standard components.
In a stabile hard case, your complete analysis-equipment is well protected. The photometer, all required indicators, test tubes as well as timer and protection glasses are easy to locate and use. Thus, the preparation time for a measuring process is reduced to the minimum.
AQUA-CHECK 2 contains solutions for titrimetric measurements of total- and carbonate hardness in our standard packaging contents.
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 |
| 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.
