Complete monitoring system for the automatic, continuous measurement of phenol C₆H₅OH in process water, wastewater and effluents.

• Phenol and its derivatives (phenols, or phenolic compounds) are moderately water-soluble pollutants, common to the wastewaters of various industries, including oil & gas, paint manufacturing, phenolic resin production, paper and pulp factories, and pharmaceutical industries.
• Excessive phenolic compounds are harmful to human health and the environment. Chlorophenols, by-products of chlorinating phenol-containing water, are carcinogens.
