Water Quality Analyzers

Fast, reliable & Continuous Online Water Analysis

Revolutionize Your Water Analysis with our LAR™ TOC Water Analyzer: Precise, Reliable, and Efficient

Our LAR™ fast and accurate water analyzers measure and monitor the most important parameters: TOC, COD, BOD, Toxicity, TNb, and Oil-in-Water.  Our water analyzers were designed to fit environmental monitoring, municipal facilities, and industrial manufacturing applications. 

Our online water quality solutions are used globally in three major areas of application: Environmental monitoring, municipal facilities and industry.  Based on our analyzers’ high precision and speed, they allow an optimal controlling of processes, safe supervision of industrial and municipal wastewater treatment plants, reliable monitoring of surface water and inflows of rivers/lakes.

We are revolutionizing measurement everywhere!

For a complete range of analytical instrumentation, applications, systems, and service options, please contact us.   We will work to match your needs and budget and provide the optimal, and most stable process analysis solution for your application.

Our QuickTOCultra™ is the ultimate online TOC analyzer for the determination of total carbon (TC), total organic carbon (TOC), total inorganic carbon (TIC) and dissolved organic carbon (DOC) suitable even for the most difficult wastewater applications. Exact Analysis at 1,200°C, the TRUE TOC is determined.


Monitoring water quality for parameters such as Total Organic Carbon (TOC), Chemical Oxygen Demand (COD), Biochemical Oxygen Demand (BOD), and Total Nitrogen (TNb) is essential for:

  • Public Health: Water is a fundamental resource for human consumption, and its quality has a direct impact on human health. Organic and inorganic compounds, as well as nutrients, can enter water sources and contaminate them, leading to health risks for those who consume it. Monitoring parameters such as TOC, COD, BOD, and TNb can help to identify the presence of pollutants and potential health risks associated with them.
  • Environmental Health: Water quality is also vital for the health of aquatic ecosystems. Toxic substances, such as heavy metals, pesticides, and other pollutants, can enter water sources and negatively impact aquatic life. By monitoring parameters such as TOC, COD, BOD, and TNb, it is possible to identify sources of pollution and take measures to reduce or eliminate their impact on the environment.
  • Compliance: Many industries, including those involved in manufacturing, agriculture, and wastewater treatment, are required to meet specific regulations for the release of wastewater and other pollutants into water sources. Monitoring parameters such as TOC, COD, BOD, and TNb can help these industries to stay in compliance with regulations and avoid costly fines and penalties.
  • Process Control: Monitoring these parameters is also essential for industries that rely on water for their processes, such as pharmaceuticals, food, and beverage production. These industries need to ensure that their processes are efficient and that the water they use is of high quality.

This century is characterized by global environmental challenges. Surface water and river water pollution is of special importance, as clean water forms the foundation of life. It therefore requires special attention in terms of quality. Regional authorities are requested to prepare measures for the improvement of water quality and to establish its provision. In order to secure sustainability in international projects, local authorities develop innovative solutions for the safety of water in cooperation with foreign companies and institutions. Lately, a variety of such joint projects are being realized around the world, with the German Federal Ministry of Education and Research especially sponsoring projects that are based on the cooperative partnership between industry and science. We at take our product responsibility seriously. For this reason, we make a continuous contribution to the development of innovative and environmentally friendly technologies.
