Modules for customized conductivity and pH measurement

High-end modules for customized pH, ion, and conductivity measurement.

With the 856 Conductivity Module and 867 pH Module, you can build your own, customized solution – whether you are analyzing large sample loads or multiple parameters, or you want to enjoy full freedom when it comes to method programming and applications.

The modules combine the highest level of flexibility and technical comfort with modern measuring technology and are fully FDA-compliant.

  • Standalone use or add-on for tiamo- or OMNIS-run Titrando systems.
  • Full freedom of method development
  • Full FDA compliance
  • Optional connection to sample changers

High-end customization: Build the setup you need

The 856 Conductivity Module and the 867 pH Module can be used either as stand-alone meters or integrated into a Titrando system that runs on the tried-and-tested tiamo software or our new OMNIS Software platform. In standalone use, you can run these modules with a 900 Touch Control unit.

If you opt for software control, you get full flexibility in method programming, access to all measuring parameters, and database functionalities.

Ensure FDA and GLP compliance

tiamo full, OMNIS Software, and 900 Touch Control are compliant with the FDA’s 21 CFR Part 11 regulation and GLP; data reports from your pH or Conductivity Module thus fulfill the requirements of any application.

The automatic, GLP-compliant electrode test as well as calibration with many buffers and automatic buffer recognition ensure that you can always rely on your results

Even more security with intelligent sensors


The 867 pH Module is compatible with the iTrodes: the built-in memory chip of these intelligent sensors allows the storage of sensor data such as article and serial numbers, calibration data, calibration history, working life, and calibration validity period. When you connect the sensor to your module, all the data is read in automatically.
