The Testomat LAB TH and the Testomat LAB TH-R (Remote) are fully automatic online analyzers for the precise determination of residual total hardness in water using automated titration. The device provides continuous, reliable measurement results in the range of 0.05–25 °dH. The instruments were developed for use in multiparameter systems and for connection to higher-level control systems.

Fully automatic residual hardness measurement for laboratory and process water using Testomat LAB

High-precision titrimetric hardness determination with data logging

The Testomat LAB TH combines high measurement accuracy with easy integration into existing measurement and automation concepts. Automatic titration using a piston dosing pump enables continuous, low-maintenance acquisition of water hardness values. All measurement data are logged in a structured format on an integrated SD card or optionally on an SDHC card. The standard interfaces 4–20 mA and RS232 allow direct data transfer to higher-level control and process control systems.

Application areas of the Testomat LAB TH and LAB TH-R (Remote)

Flexible use in laboratory, process, and drinking water monitoring

• Water treatment plants
• Drinking water systems
• Industrial boilers
• Process water monitoring

Technical highlights and performance features of the Testomat LAB TH

The Testomat LAB TH features optical water detection during filling of the measuring chamber, automatic venting of the indicator line, and an integrated self-test for continuous system monitoring.

Benefits of hardness measurement within the LAB multiparameter system

Thanks to the integration capabilities of the Testomat LAB in a manufacturer-independent multiparameter system, precise and continuous online monitoring of water hardness is possible within a central measurement platform. Automatic titrimetric measurement delivers reliable and reproducible results and can be easily integrated into existing process and control systems via standardized interfaces. This increases process reliability and reduces maintenance and personnel costs.
