Description

Hydrogen peroxide (H2O2) is an extremely strong oxidizer widely used in bleaching applications in the paper industry. It has also been used in a variety of applications including disinfection, odour control, oxygenation, and cyanide oxidation. It is frequently used in wastewater collection systems to remove hydrogen sulphide that destroys concrete pipes and manhole structures. Peroxide applications in aqueous systems, like most chemical treatment processes, function most efficiently with accurate measurement and control.

ATI’s Model Q46/84 Hydrogen Peroxide Water Quality Monitor is designed to continuously measure the concentration of H2O2 in aqueous systems. Using a direct peroxide sensor, the unit responds rapidly to changes in concentration, enabling operators to control chemical feed to maintain specific targets. With both digital and analogue communications available, the Q46 is adaptable to a wide variety of peroxide monitoring applications.

Key Facts

  • Flexibility. Programmable range options from 0-2 PPM up to 0-200 PPM provide maximum application flexibility.
  • AC or DC Power Options. Power options include universal 90-260 VAC or 12-24 VDC.
  • Analog Output Options. Two isolated 4-20 mA outputs are standard, with an option for a third output if required. Default setting provides analog outputs for H2O2 and temperature.
  • PID Output. Standard PID control function assignable to one analog output.
  • Digital Communications. Available in either Profibus-DP, Modbus-RTU, Modbus-TCP/IP, or Ethernet-IP.
  • Relay Outputs. Three SPDT relays are standard, with relay functions programmable for alarm, control, or trouble indication. Three additional low power relays available as an option.
  • Flexible Mounting. NEMA 4X (IP-66) enclosure is suitable for wall, pipe, or panel mounting.
  • Clear Display.Back-lit large LCD display provides clear visibility in any lighting conditions. A scrolling second line on the display provides additional information and programming prompts
