LAR's online measuring instruments offer solutions to (almost) all applications. This is due to the fact that we listen carefully to our customers, getting to know your application so that we can offer the solutions specific to your needs. In our company, individuality means that one single family of instruments allows for versatile and exactly tuned measurements.

Through our constant research and development work we know the challenges in the different fields of applications. Our measuring instruments analyse the total organic carbon (TOC) precisely and reliably from the lowest to the highest levels of concentrations. This also applies for determining the chemical oxygen demand (COD), biochemical oxygen demand (BOD), total phosphorus (TP), total nitrogen (TNb) and toxicity.

Types of Water

The requirements for online measurements in pure water are very different. Read more about the importance of reliable measurements and about challenges of these applications.

As any disturbance in process water circuits (e.g. water-steam-circuits) can lead to an entire plant shutdown, reliable and fast application-specific online water analyzers provide huge advantages.



Fluctuating loads, water with a high particle density and high salt concentrations characterise waste water.
