The peracetic acid monitor provides real time measurement of peracetic acid in solution.

Peracetic Acid (PAA) is a strong oxidiser used in the food industry to disinfect piping systems and processing equipment. It is also used for spray washing of food products and for disinfection of cooling water systems.

As with any disinfection system, maintaining proper residual values is key to effective pathogen control. To facilitate reliable chemical feed control, ATI has developed an on-line water quality monitor capable of providing real time measurement of low levels of PAA in solution. The Q46 85 peracetic acid monitor uses a direct sensing polarographic probe either in a flowcell or submersible. A permeable diffusion membrane isolates the sensing electrodes from the measured sample, providing long-term stability without electrode fouling problems. The measurement is selective for peracetic acid and is not affected by changes in hydrogen peroxide concentration, which is always present in PAA solutions.
