HY517-A OIW sensor detects the aromatic hydrocarbons (PAH) in water. The oil in water sensor measures the fluorescence of the hydrocarbon components in the water excited by UV light. An oil molecule absorbs the UVC light energy and then emits fluorescence light. UV fluorescence measurement method provides high sensitivity and selectivity toward PAH detection
Overview
HY517-A OIW sensor detects the aromatic hydrocarbons (PAH) in water. The oil in water sensor measures the fluorescence of the hydrocarbon components in the water excited by UV light. An oil molecule absorbs the UVC light energy and then emits fluorescence light. UV fluorescence measurement method provides high sensitivity and selectivity toward PAH detection
