The Process Insights Portfolio:


LAR Process Analyzers

The LAR product portfolio includes water analyzers for the most identifying and monitoring: TOCCODTODBODtoxicityTN, and oil-in-water.

Applications the LAR water analysis systems are primarily used in:

  • Environmental
  • Municipal 
  • Industrial

LAR – Total Organic Cardon (TOC) Analysis

LAR Process Analyzers available from Territory Instruments, Authorised Partner for DRUCK in Australia, New Zealand and Papua New Guinea (ANZ & PNG).

A whole variety of organic matter can be present in water, which cannot be determined individually. At least not without considerable analytical effort and within a short time. This is why the so-called sum parameter TOC (total organic carbon) is used.

The TOC measures a samples organic loads and is thus an important indicator for water quality. Since it includes all carbon compounds as one mass, it is exactly defined and an absolute quantity. Therefore, it may be determined directly.

The Total Organic Carbon (TOC) is one of the most important composite parameters in the assessment of the organic pollution of water. Since it includes all carbon compounds as one mass, it is exactly defined and an absolute quantity. Therefore, it may be determined directly. In relation to the TOC also parameters like TC, TIC, DOC, (POC, VOC) are mentioned. The connections between these sum parameters.




The total nitrogen bound (TNb) defines the total pollution of water by nitrogen compounds. It is an analytical parameter for water and is specified in mg/l.

The pollution of nitrogen can appear in form of ammonia, ammonium salts, nitrites, nitrates and organic nitrogen compounds. In contrast to its individual determination, the TNbcovers all components in one analytical run. The determination of the TNb value is standardized by the German Institute of Standardisation (DIN EN 12260:2003).

LAR – Chemical Oxygen Demand (COD) Analyzers


The chemical oxygen demand (COD) indicates the amount of oxygen which is needed for the oxidation of all organic substances in water and is thus an important indicator for water analysis. It is considered in the planning and controlling of treatment, as well as assessing its efficiency, thus forming the basis for the calculation of wastewater charges.

The COD can be determined in a laboratory or online, whereby these methods significantly differ in duration and consumables used.

LAR BOD Analyzers


The biological or biochemical oxygen demand indicates the amount of oxygen which is needed for the biological degradation of organic substances in water.

Generally, the BOD5 is perceived as the BOD for controlling wastewater treatment plants (WWTP). However there are nitrification inhibitors added to the BOD5 to surpress the nitrogen degradation. Obviously, the nitrification is an important part of the biological degration of organics and thus is very important for the control of WWTPs. Consequently, the BOD5 ist poorly suited for the control of wastewater treatment plants.

Alternatively, the total BOD is well-suited, due to the determination of the nitrogen as well as the carbonaceous part of biological degradation.

LAR Relative Humidity – Type 85



LAR’s toxicity analyzer ToxAlarm continually monitors drinking and surface water for pollutants. Potential toxins in water are determined through the reaction of highly sensitive bacteria. The measurements follow at intervals of less than 5 minutes even after events of toxicity.


  • Measurement range: 0-100% Toxicity
  • Response time: 5-10 minutes (application dependent)
  • Continuous monitoring of toxicity
  • Self-regenerating bacteria within toxicity analyzer
  • High reproducability
  • Low operational costs
  • Low maintenance
  • No purchase of test organisms necessary
  • According to DIN EN ISO 9509:2006
