Water oil sensor

Water oil sensor

Organic matter dissolved in water, such as CDOM/fDOM, is an optically measurable component of organic matter dissolved in water. For example, petroleum, monocyclic polycyclic aromatic hydrocarbons dissolved in water after emulsification, and PTSA used for water treatment process monitoring all emit fluorescence longer than the absorption wavelength under the excitation of ultraviolet short wave light.

Frog Vision provides a UV fluorescence sensor for detecting fluorescent agents such as CDOM/fDOM, petroleum, PTSA, etc. in water.

Advantages: • Adopting fluorescence method; Only a small distance from the obstacle is needed to avoid its impact; • Implement long-term online monitoring; Using PTSA solution calibration, it has good linearity with the vast majority of fluorescent organic compounds to be detected by users. • Note: PTSA (1,3,6,8-pyrene tetrasulfonic acid tetrasodium salt, CAS accession number 59572-10-0)
