  • 912/913/914 pH/Conductometer

    Available options 912, 913, 914 pH/konduktometre

    The 912 Conductometer, the 913 pH Meter, and the combined 914 pH/Conductometer offer you high flexibility as they are mobile and lab meters in one instrument. These easy-to-use instruments are ideal for routine use.

    • Measure pH, ORP, conductivity, TDS, salinity, and temperature
    • Suitable for outdoor use: IP67, rechargeable battery, comfortable hand-held use
    • Clearly organized user interface for intuitive use
  • 780/781 pH/Ion meter

    Available options 780 pH Meter

    The 780 pH Meter and the 781 pH/Ion Meter are characterized by their advanced technical comfort. This includes numerous possibilities in terms of parameter and method settings as well as integrated quality control tools.

    • Measure pH, ORP, concentration, Ipol, Upol, and temperature
    • Connections for direct control of stirrers, dosing devices, printers, etc.
    • Integrated quality control, e.g., through user identification and GLP-compliant electrode test
  • 867/856 Modules

    Available options 867 pH Module

    The 867 pH Module and the 856 Conductivity Module can be used as add-ons for Titrando systems or as stand-alone meters. When dealing with large sample loads or multiparameter analyses – or if you’re looking for the highest level of technical comfort – these modules are the right choice.

    • Measure pH, ORP, concentration, conductivity, TDS, salinity, and temperature
    • Various easy automation options
    • Flexibility, security, and FDA compliance with 900 Touch Control or tiamo software for control
