Water Testing Kits - Test Kits (Drop Count)

Total or M-Alkalinity Test Kit

Procedure: Small amount of sample is collected in a test tube and an indicator reagent is added to the sample. Use the dropper bottle, the titrant, until the color changes. To calculate the concentration just multiply the number of drops required by the titrant by a simple factor given in the test kit manual. The sample is titrated with Sufuric acid to a colorimetric end point corresponding to a specific pH. Total Alkalinity is determined by titration to a pH of 4.5 by using mixed Bromocresol Green Methyl Red indicator.

Acidity Test Kit

Procedure: Small amount of sample is collected in a test tube and an indicator reagent is added to the sample. Use the dropper bottle, the titrant, until the color changes. To calculate the concentration just multiply the number of drops required by the titrant by a simple factor given in the test kit manual. Acidity of a water is its quantitative capacity to teact with a strong base to a designated pH,. Acids contribute to corrosiveness and influence chemical reaction rates, chemical speciation, and biological process. The measurement also reflects a change in the quality of the source water.

Process Instruments - Drinking Water

Process Analyzer for The Determination of Chlorine Dioxide

WATERLINE CLO2 process analyzer can be used for the monitoring and control of the chlorine dioxide concentration in water. Measurement principle is the determination of chlorine dioxide by dosing a special developed reagent to a buffered water sample until the sample changes its colour (titration). The colour change is detected by a monochromatic photometric detection system. The measurement is selective (no influence from other chlorine species in drinking water relevant concentrations). The analyzer consists of a control unit with touchscreen and an analysis unit with measuring chamber, valve, dosing pumps and all required tube connections. The control unit includes a microprocessor which controls the automatic measurement incl. sampling, rinsing, reagent dosing and surveillance of the photodetection system.
