ATI Q46H/62-63 Residual Chlorine Monitor

Key Facts

• Free or Combined Chlorine. Q46H Monitors are factory set for either Free or Combined Chlorine measurement, but can easily be converted from one to the other in the field.
• Economical Operation. Reagent-less operation and low parts cost makes the Q46H your best choice for chlorine monitoring applications in potable water, wastewater, cooling water, or high purity water systems.
• Automatic pH Compensation. For free chlorine monitoring under widely varying pH conditions, automatic pH compensation may be added to maintain the highest measurement accuracy at pH levels up to 9.5.
• Dual Chlorine/pH Monitoring. Even when pH correction is not required, adding a pH sensor to the system converts the monitor to a dual analyzer, providing 4-20 mA outputs for both chlorine and pH.
• Flexibility. Programmable range options from 0-200 PPB 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 chlorine and pH.
• 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.
