When potentiometric titration reaches its limitations: Thermometric titrator for the determination of sodium, FFA, or TAN/TBN among others.

Titrotherm is a thermometric titrator for fast determinations when potentiometric titration cannot be applied. It is particularly useful for the analysis of sodium in foodstuffs, free fatty acids (FFA) in edible oils and fats, total acid number (TAN) and total base number (TBN) in mineral oil products, as well as acid mixtures in electroplating baths.

  • Only one sensor is needed to perform all thermometric titrations
  • No sensor calibration or maintenance is required
  • Automation options are available to keep up with higher throughput
  • Customized methods with the intuitive tiamo software

One sensor for all applications


As Titrotherm uses a temperature sensor, you only need one sensor for all your thermometric applications. This means that cumbersome and time-consuming tasks are no longer needed:

  • No sensor calibration or maintenance required
  • No sensor exchange required for different applications

Automation for higher throughput

Automate your Titrotherm system with a sample processor to run sample series automatically while increasing the reproducibility, precision, and accuracy of your results.

Depending on your requirements, you can have the sample processor that matches exactly your needs: with one or two towers for parallel operation and with or without internal or external pumps for aspirating and rinsing.

Smart software for customization

Titrotherm is controlled with the tiamo software. You are thus able to develop and optimize your own methods. This software also recognizes the instrument automatically when it is connected to the computer.

What is thermometric titration?

In contrast to potentiometric titration, where a potential change is measured, thermometric titration measures the temperature change in the titration solution that results from the reaction enthalpy.

Every chemical reaction is accompanied by a change in enthalpy, meaning that, as long as a reaction takes place, there is either an increase (exothermic reaction) or decrease (endothermic reaction) in the temperature of the titration solution. This technique can therefore be applied for difficult samples or matrices where potentiometric titration is difficult or not feasible such as the determination of sodium, the acid number, or base number.

What are the advantages of thermometric titration?

  • Problem solver for difficult samples that cannot be titrated with potentiometric titration
  • Only one temperature sensor is needed for all applications - no sensor calibration or maintenance required
  • Robust method for routine work
  • Rapid results
