Brand：Erun
On-line analyzer for oil (PAHs) water quality in water
Model：ERUN-SZ4-A-J4C
Parameter：Oil (UV fluorescence method)
The ERUN-SZ4-A-J4C online water quality analyzer for oil (PAHs) in water, developed and manufactured by Erun Environmental Protection, stands out for its excellent efficiency and swiftness, and shows excellent measurement repeatability. The instrument is designed for real-time monitoring of ppb-level trace oil content in water bodies, ensuring accurate data. A dedicated sensor with integrated self-cleaning brush function eliminates air bubbles and oil residues and significantly reduces the risk of contamination interfering with the results, thus significantly extending maintenance intervals. Even under long-term online operation, ERUN-SZ4-A-J4C can maintain excellent stability performance, providing reliable monitoring and early warning service for oil pollution in water, which is a powerful assistant in the field of environmental protection monitoring.
