The UV-Absorption Organics Monitor that simplifies your water treatment processes.

About the AMI SAC254

The AMI SAC254 is an on-line monitor that continuously measures UV-absorption, a surrogate parameter to determine dissolved organics (DOC, TOC, etc.), at a wavelength of 254 nm.

Subsequently, this instrument allows you to save chemicals, energy and time by improving the efficiency and efficacy of (individual) treatment steps, such as coagulation/flocculation, activated carbon adsorption and UV disinfection.
