Titramax VT

Determination of carbonate and bicarbonate hardness of water

The Titramax VT ALKALINITY is suitable for determination of carbonate and bicarbonate hardness of water samples. The alkalinity of natural waters is primary caused by hydroxyl ions in free state and the salts of carbonate and bicarbonate along with borates, silicates and phosphates.

The device is conform to standards ASTM D 1121, DIN EN ISO 787-4, DIN ISO 125, ISO 10539.

The measurement uses a volumetric titration method with sulphuric acid or hydrochloric acid (0.01 – 0.1 mol/L).

Once the water sample is dosed into the reagent, the titration with acid starts. The user has to enter the sample weight into the menu. The titration speed is precisely adjusted to the reaction rate by control algorithms.

The titration is performed automatically until the endpoint indication of measurement. At the end of the measurement, results are shown in mg/L CaCO3 or mmol/L °dH (degrees of German hardness) or several other units.

Applications

Alkalinity values are the basis for correct dosage of chemicals for treatment of water and wastewater.

The instrument is suitable for analysis of

• drinking water
• surface water
• seawater
• technical waters
• boiler water
• cooling water

Advantages

• Complete measuring system for the determination of alkalinity
• Fully-automatic volumetric titration
• Precise adjustment of the titration parameters by control algorithms
• Preset measurement method allows an immediate start
• The result output can be adjusted to your needs by using a formula generator
