Analytical Technology Q45H/84 Hydrogen Peroxide Monitor - 1

Model Q45/84 Hydrogen Peroxide Monitor Hydrogen peroxide (H2O2) is an extremely strong oxidizer which is widely used in bleaching applications in the paper industry and is sometimes added to water systems for the purpose of disinfection. In addition, it is used in wastewater collection systems to remove hydrogen sulfide that destroys concrete pipe and manhole structures. Peroxide applications in aqueous systems, like most chemical treatment processes, function most efficiently with accurate measurement and control. In order to facilitate the control of aqueous hydrogen peroxide feed systems, ATI has developed an on-line monitor cable of providing real time measurement of low levels of dissolved H2O2 in solution. The Dissolved Hydrogen Peroxide Monitor uses a direct sensing polarographic probe mounted in a flowcell to measure H2O2 in a flowing water stream. A peroxide permeable diffusion membrane isolates the sensing electrodes from the measured sample, providing long-term stability without electrode fouling problems. The measurement is selective for peroxide and does not respond to most other ions in solution. l Available in AC powered, battery powered, or 2-wire loop-powered versions l Real time Peroxide 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 0-2, 0-20, or 0-200 PPM operator selectable l Direct reading H2O2 sensor requires minimal maintenance l Nema 4X (IP-66) electronic packaging suitable for wall or panel mounting Features
