  • PCE Instruments PH 25 Conductivity Meter

    # PH 25

    • The pH meter provides the user with comprehensive measurement applications. In addition to determining the pH value, the pH meter also shows the conductivity, the filtrate dry residue, the salinity and the temperature of the sample.
    • The pH meter is a measuring instrument for mobile measurement. In order to facilitate the most comfortable transport, the pH meter is supplied with a practical belt clip into which the measuring instrument can be inserted.
    • In contrast to a normal pH meter, there are many possibilities to perform a liquid analysis. The scope of application ranges from the diagnosis of private aquariums to the examination of water bodies or swimming pools.
