The proven solution for on-site measurement of pH, conductivity and total hardness in the heating water
The evaluation of the heating water, especially in regard to the electrical conductivity of the heating water, the pH value of the heating water and the total hardness of the heating water, is decisive for a heating water quality according to VDI 2035 and other guidelines. The observation of these values is of great importance for the installer and the operator of a heating system, because warranty claims often depend on the heating water quality.
We have arranged the heating water analysis set in the practical case for on-site use, so that the heating engineer, the caretaker or any other person can ascertain the important parameters of the heating water, pH value, electrical conductivity and total hardness directly at the system.
The total hardness measurement is done by use of an total hardness drop test. For this purpose, 5 ml of heating water are poured into the enclosed cuvette. By constant swirling of the heating water the hardness solution is to be added dropwise, whilst the drops are counted. The number of the drops corresponds to the total hardness of the heating water. The use of a total hardness drop test is a cost-effective and proven method for the observation of the total hardness of heating water.
For measurement of the electrical conductivity of the heating water and to observe the pH value of the heating water, we have enclosed our electronic analysis device MP-7 to the heating water analysis kit. The MP-7 is used by many installers, service engineers and maintenance staff for the rapid on-site heating water analysis. The heating water analysis device MP-7 is very reliable and easy to use.
