With its high quality products for online measurements and their accuracy, LAR AG decisively contributes to the improvement of the environment. At the same time, the industry concerned also profits from LAR's provision of accurate data for process water applications. Hence, our innovative and precise measurement technique ensures the balance between environmental protection and industry. In order to do this a fair and constructive cooperation with our customers and our partners is an important maxim for any of LAR's activity.

LAR AG was established in 1986 and has always been a customer-oriented company. Its main business scopes are the development, manufacture and distribution of state-of-the-art products for water analysis, based on a constant dialogue with users.

LAR AG has a quality management system certified in accordance with DIN EN ISO 9001:2008, continuously making adjustments to meet the current quality requirements to the latest standards.



LAR's product range covers water analyzers for the most important sum parameters as TOC, COD, TOD, BOD, toxicity, TN, TP, and Oil-in-Water. The measurement systems are used in three major areas of application: Environmental monitoring, municipal facilities and industry.

Based on the analyzers' high precision and speed, they allow an optimal controlling of processes, safe supervision of industrial and municipal waste water treatment plants, reliable monitoring of surface water and inflows of rivers/lakes.

  • TOC Analyzer

    The Total Organic Carbon (TOC) measures a samples organic loads and is thus an important indicator for water quality. From complex industrial waster water to phamaceutical pure water, LAR's TOC analyzers determine the parameter quickly and precisely.

    • QuickTOCpharma
    • QuickTOCeffluent
    • QuickTOCuv
    • QuickTOCNPO
  • COD Analyzer

    The Chemical Oxygen Demand (COD) indicates the amount of oxygen which is needed for the oxidation of all organic substances in water. Conventional methods need toxic and hazardous oxidants. On the contrary, LAR's COD analyzer determine the parameter cleanly and safely without using hazardous chemicals - online as well as in laboratory use.

    • QuickCODlab
    • Elox100
  • BOD/Toxicity

    The Biochemical Oxygen Demand (BOD) indicates the amount of oxygen which is needed for the biological degradation of organic substances in water. Toxicity is described as the direct harmful effect of a substance on organisms. Both, BOD and toxicity, are important parameters for the control and protection of waste water treatment plants.

    Toxicity Analyzer
    • NitriTox
    • ToxAlarm
  • TN/TP Analyzer

    The total nitrogen bound (TNb) shows the pollution of water caused by nitrogen compounds. Using LAR's ultra high-temperature method, the TN can be determined by using a CLD or ECD. The total phosphorus (TP) is determined by the molybdenum blue method. However, this parameter can be combined with TOC, COD and TN measurements in one single analyzer.
