LAR Process Analysers AG was founded in 1986 by Dr. Werner Arts in Berlin, Germany. As of 2025, this makes the company 39 years old. LAR specializes in developing and manufacturing advanced water analysis solutions, particularly focusing on parameters such as Total Organic Carbon (TOC), Chemical Oxygen Demand (COD), Total Nitrogen (TN), and Biological Oxygen Demand (BOD). Their analyzers are widely used in industrial, municipal, and environmental applications.

Today, LAR’s application-specific analyzers play a crucial role in optimizing both industrial and municipal wastewater treatment plants, ensuring effective process control and environmental compliance. Additionally, they support environmental monitoring efforts, helping safeguard natural water sources.

LAR’s cutting-edge water quality measurement systems deliver reliable, real-time monitoring of critical parameters including TOC (Total Organic Carbon), TNb (Total Nitrogen bound), TOD (Total Oxygen Demand), COD (Chemical Oxygen Demand), BOD (Biological Oxygen Demand), and toxicity.

Moreover, these advanced systems help:

• Optimize and control measurement processes with high accuracy
• Ensure safe and continuous supervision of wastewater treatment operations
• Provide dependable monitoring of surface waters, rivers, and lake inflows

By integrating our proven technologies, facilities can not only improve water quality management but also comply with strict regulatory standards while reducing operational risk.
