Measurement Principle

　　Based on 4-aminoantipyrine colorimetric method to measure volatile phenol content in water. It meets the national standard “Environmental Quality Standard for Surface Water” (GB 3838-2008), “Determination of Volatile Phenols in Water Quality 4-Amino Antipyrine Spectrophotometric Method” (HJ 503-2009) for the determination of volatile phenols, and can be widely used for online monitoring of volatile phenols in water.

Main features

　　Touch screen display and command input, multiple sampling and measurement modes, unique design, lower failure rate, lower maintenance, lower reagent consumption and higher cost performance.
