Laboratory and industrial analysis of COD of effluents of any industry
Hach has developed a range of complete solutions adapted for laboratories and factories performing COD tests. Coordinated instrumentation and reagent systems enable you to run your analysis safer, faster, and with confidence in your results.
High range hardness reagent kit, 100 - 4000 mg/L as CaCO3
The first titration gives results for the calcium hardness and the second titration gives the total hardness. The difference between the values is the level of magnesium hardness. All concentration results are given in mg/L CaCO3.
Low range hardness reagent kit, 10 - 160 mg/l CaCO3
The first titration gives results for the calcium hardness and the second titration gives the total hardness. The difference between the values is the level of magnesium hardness. All concentration results are given in mg/L as CaCO3.
Test kit for determination of total and calcium hardness by drop count titration / EDTA. Magnesium hardness can be calculated from the difference in the values obtained; range 20 - 400 mg/l CaCO3, 100 tests.
