Chemical analysis for water

Categories: ,

Description

Quick, simple tests for the analysis of boiler water, cooling water, drinking and industrial water. Using tablet reagents with long-term stability.

Advantages: easy operation and exact reagent dosing without any additional equipment, measurement accuracy even in difficult operating environments, unrestricted shipment and safe storage, foil-wrapped Lovibond® tablet reagents with a minimum guaranteed shelf life of 5 years, each kit contains sufficient reagents for an average 30 tests.

The methods

Tablet count method: the liquid titration solution and indicator are replaced by Lovibond® tablet reagents. A specific number of tablets is added to a defined sample volume until a chemically induced colour change takes place. The concentration of the parameter being measured is calculated from the number of tablets required. The measuring range can be expanded by varying the sample volume.

Speed test: is based on reverse titration. After adding a reagent tablet to a calibrated test tube, the water sample is added slowly until the colour of the solution changes (e.g. from red to blue). The user can then obtain the result from the liquid level.

Yes/No test: tells the user whether a specific ingredient is present in the water and/or if its concentration is higher or lower than a defined level.

Turbidity method: a two-section calibrated test tube is filled with the water sample and a reagent tablet added. The reagent creates a level of turbidity that is proportional to the concentration of the parameter being measured. The inner tube, which has a black dot on its base, is lowered until the dot is obscured by the turbidity. The result is read off from the water level in the inner tube.
