Continuous Water Quality Monitoring of H2O2

ATi’s 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 analog communications available, the Q46 is adaptable to a wide variety of peroxide monitoring applications.

The Q46/84 sensors are capable of operating over a fairly broad concentration range, from a low range of 0-2 PPM up to a high range of 0-200 PPM.

Features & specification

Programmable range options from 0-2 PPM up to 0-200 PPM provide maximum application flexibility.
AC or DC Power 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
Standard PID control function assignable to one analog output.
Available in either Profibus-DP, Modbus-RTU, Modbus-TCP/IP, or Ethernet-IP.
Three SPDT relays are standard, with relay functions programmable for alarm, control, or trouble indication. Three additional low power relays available as an option.
NEMA 4X (IP-66) enclosure is suitable for wall, pipe, or panel mounting.
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.
Flow control and flowcell options.
