LAR BioMonitor from LAR Germany is an online BOD analyzer for the determination of biochemical oxygen demand (BOD), respiration and toxicity in waste water. By using own activated sludge from plant, BioMonitor can accurately performing BOD measurement in short time and thus efficiently control their waste water treatment plant in an optimal way.
It not only measure BOD, but it simultaneously measures Activated Sludge Respiration (ASR) which is an important indication on the condition of plant’s biomass.

The patented measuring method of the LAR BioMonitor works just like a miniature treatment plant !!
