MP-7, The proven solution for on-site measurement of pH, conductivity and total hardness in the heating water.

Special attention and water testing to comply with VDI 2035 is required. 

The flowing three key factors if controlled correctly will greatly reduce corrosion. 

  1. Electrical conductivity.

  2. The pH value.

  3. The total hardness.


The observation of these values is of great importance for the installer and the operator of a heating system. 


Warranty claims against manufactures products are often depend on the heating water quality.


The MP-7 is a heating analysis kit which is supplied in practical case for on-site use.This kit allows the engineer to assess the important parameters of the heating water (pH value, electrical conductivity and total hardness).

For measurement of the electrical conductivity & pH value the kit incorporates our electronic analysis device the MP-7. 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.

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 test tube and by constant swirling of the heating water the hardness solution is to be added drop by drop with 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.

Easy To Use

The combination meter not only automatically recognises the electrodes, it also has a logical operation and a large, easy-to-read display in a robust housing.

Proven methods

To measure the total hardness of the heating water, a drop test is integrated in the elector heating water test kit. This can be used to observe the heating water total hardness by means of the colour swap method.

Integrated measurement logic

The microprocessor controlled analysis device MP-7 is easy to use. The device detects the electrodes and automatically switches between pH and electrical conductivity measurements.

Reliable results

The analysis device MP-7 is also suitable for the measurement of pH and electrical conductivity in water with low salt content. To ensure that the device remains accurate over the long term, standardised calibration solutions from brand manufacturers are included in the scope of delivery and are available as consumables.
