Analytical Technology Q45H/85 Peracetic Acid Monitor - 1

Mooddeell Q45//885 Peracetic Acid Monitor Peracetic acid (PAA) is an extremely strong oxidizer widely used in the food industry for disinfection of piping systems and processing equipment. It is also used for spray washing of food products, and for disinfection of cooling water systems. As a disinfecting agent, PAA is often preferred because it produces no harmful breakdown products. As with any disinfection system, maintaining proper residual values is the key to effective pathogen control. To facilitate reliable chemical feed control, ATI has developed an on-line monitor cable of providing real time measurement of low levels of PAA in solution. The Q45/85 Peracetic Acid Monitor uses a direct sensing polarographic probe mounted in a flowcell to measure PAA residuals in a flowing water stream. 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 PAA, and is not affected by changes in hydrogen peroxide in solution. l Available in AC powered, battery powered, or 2-wire loop-powered versions l Real time PAA measurements suitable for chemical feed control l Standard PID control output l Second analog output plus two alarm or control relays on AC powered units l Large, easy to read LCD display with LED back-light l Display ranges of 0-20, 0-200, or 0-2000 PPM operator selectable l Direct reading PAA sensor requires minimal maintenance l Nema 4X (IP-66) electronic packaging suitable for wall or panel mounting Features
