More Information:
The RMR-2009 is a titration-based chemical test kit that determines the Dissolved Oxygen in water by the ppm concentration, 0.5 ppm/drop.
The RMR-2009 is supplied with all of the necessary reagents and equipment to perform the analysis. The test kit contains enough reagents to perform approximately 100 tests.
Features at-a-glance
- Measures aqueous Dissolved Oxygen (DO) levels quickly.
- Reads levels from 0.5 ppm to 20 ppm.
- Resolution 0.5 ppm / Drops.
- Tolerance ± 0.5 ppm.
- Fast, easy and accurate test results.
- Includes all equipment required to perform the test.
- Economical and Conducts 100 tests.
Complete setup
- All required materials are included with the test kit, such as the sample tube, Sample collecting syringe, 6 Bottle with pre-made Reagent.
Mechanism
-
- Step 1 : A modified Winkler method is used in the RMR-2009 test kit. Manganous ions react with oxygen in the presence of potassium hydroxide to form a manganese oxide precipitate
- Step 2 : With the addition of acid, manganese oxide hydroxide oxidizes the iodide to iodine. ( No Toxic & Hazardous Azide But our formulation prevent any nitrate ions from interfering with the test. )
- Step 3. Since the amount of iodine generated is equivalent to the oxygen in the sample, the concentration of iodine is calculated by titration of thiosulfate ions that reduce the iodine back to iodide ions.
- Step 1: 2Mn2 + O2 + 4OH– → 2MnO(OH)2
- Step2: MnO(OH)2 + 2I– + 4H → Mn2 + I2 + 3H2O
- Step 3: I2 + 2S2O32– → S4O62-
Significance of Use
The concentration of dissolved oxygen in water is extremely important as well in man’s environment. In oceans, lakes, rivers, and other surface water bodies, dissolved oxygen is essential to the growth and development of aquatic life. Without oxygen, water can become toxic due to the anaerobic decaying of organic matter. Water must contain at least 2 mg/L of oxygen to protect water pipes from corrosion.
However, The test is essential for Fisheries, Ponds, Bio-flock, Boiler system water and in many cases.
