Testomat Modul TH


Cost Effective Analyzer for Total Hardness

The Testomat® Modul TH is a hardness analyzer that is used to determine and monitor total hardness via titration and photoelectric evaluation. Depending on the reagent, it can cover a range from 0.89 - 448 ppm, see below. 

The Testomat® Modul TH sends the measurement result to a PLC via a

4-20mA output signal. Additionally, the measurement results can be saved on a SD-Card. (SD-Card not included)

The Testomat® Modul TH combines the measuring technology of the Testomat® family with a reduced technical design, which lowers cost and maintenance effort.


This analyzer comes without a display, and a PC/Laptop is required for configuration. A display is optional available.
