Measure phenol in water - 0 to 200 ppm


Phenols may occur in domestic and industrial wastewaters, natural waters and potable water supplies. Chlorination of such waters may produce odorous and objectionable-tasting chlorophenols. Phenol removal processes in water treatment include superchlorination, chlorine dioxideor chloramine treatment, ozonation and activated carbon absorption.


Tytronics’ Sentinel is an on-line colorimetric analyzer that measures phosphate using methods that duplicate the procedures from the Standard Methods for the Examination of Water and Wastewater, APHA, AWWA, WEF. The instrument uses a batch sampling technique that allows the use of 0.25” tubing for sample lines so small amounts of solids will not affect instrument performance.

Other advantages of batch sampling are:

  • Analytical results are not affected by sample and reagent flows.

  • Analyses are only performed as frequently as required, minimizing reagent consumption. Features:

  • Provides continuous on-line analysis of water or wastewater stream;

  • Ensures maximum reliability;

  • Ease of maintenance, rugged design;

  • Self-checking for easy diagnostics;

  • Minimizes sampling requirements;

  • Multiple communication ports, including bi-directional RS 232.


Phenol compounds react with 4-aminoantipyrine at pH 7.9 in the presence of potassium ferricyanide to form a colored antipyrine dye. This dye is kept in aqueous solution and the absorbance is measured at 540 nm.
