The Testomat® 2000 has been in use worldwide since the early 2000s for reliable monitoring of water treatment plants in industry and municipal facilities. The compactly designed online analyzer is mainly used for measuring water hardness and for the alkalinity parameters carbonate hardness, m- or p-value.

However, the Testomat® 2000 does more than just determine water hardness.

In the chemical treatment of boiler feed water, conditioning agents are used for pH adjustment (alkalization), hardness stabilizers for binding dissolved oxygen and for preventing scale deposits. The dosing process, chemical effectiveness and concentration of chemical products, such as sulfite and phosphates, must be checked based on the respective guidelines and regulations. Continuous online analysis with the following Testomat® 2000 instruments offers you sustainable operational reliability:

  • Testomat® 2000 Sulfite 
  • Testomat® 2000 Phosphate

The conditioning of recirculating water in recooling plants also requires sustained monitoring of critical quality parameters. In addition to monitoring phosphate-containing products, conditioning agents based on polymers, such as polyacrylates in the cooling water, can be detected using the 

  • Testomat® 2000 Polymer.

VDI guidelines 2047-2 and 3803-3.4 require the operator of the recooling plant to ensure hygienic operating conditions. Accordingly, a biocide treatment program must be scheduled, especially for Legionella prophylaxis. The dosage and decay behavior of chlorine-containing products and odorless chlorine dioxide can be regularly monitored and documented using the following online analyzers:

  •  Testomat® 2000 Chlorine Dioxide 
  • Testomat® 2000 Chlorine 
  • Testomat®LAB Chlorine 

Further selected application examples for the use of Testomat® analyzers for the measurement of chlorine dioxide, free or total chlorine according to the DPD method

  •  Water and plant disinfection with chlorine dioxide in the food industry 
  • Monitoring the degradation of residual chlorine in process water to protect membranes 
  • Swimming pool water disinfection with chlorine-containing products 

In water treatment for swimming pools, bromine-containing products can be used as disinfectants as an alternative to chlorine, depending on the system concept and country-specific regulations. Compared to chlorine, bromine dissolved in water is odorless and less aggressive on materials:

  •  Testomat® 2000 Bromine 

The treatment of well water requires reliable filtration or deferrization to ensure permissible drinking water and process water quality: 

  •  Testomat® 2000 Iron 

Chromate compounds are produced in metal processing, electroplating and dyeing processes and must be removed from wastewater due to their high toxicity. Continuous monitoring can be carried out using the 

  •  Testomat® 2000 Chromium VI.

The supply of ultrapure water to clean steam generators for autoclaves and sterilizers in hospitals requires sustained monitoring of important water parameters, including silicate content. Our online analyzer 

  •  Testomat® 808 Silicate  

is available. 

In summary, it can be said that the Testomat® online analyzers are not only convincing in reliable water hardness measurement, but also in the control of important dosing agents, such as sulfite, phosphate or chlorine, and critical water constituents such as iron, chromate or silicate.
