ATi’s Residual Chlorine Monitor, an upgraded version of the Q45H system, is designed for continuous water quality monitoring of free or combined chlorine. Here are some of its features and specifications:

  1. Measurement Capabilities: The monitor can measure both free and combined chlorine levels in water.
  2. Economical Operation: The Q46H system is cost-effective to purchase and maintain, providing long-term accuracy and reliability.
  3. Automatic pH Compensation: An optional automatic pH compensation feature can be added to ensure the highest accuracy in free chlorine measurement.
  4. Dual Chlorine/pH Monitoring: The system can monitor both chlorine and pH levels simultaneously.
  5. Programmable Range Options: The monitor offers programmable range options from 0-200 PPB (parts per billion) up to 0-200 PPM (parts per million), providing flexibility for various applications.
  6. Power Options: The monitor can be powered by either AC or DC power sources.
  7. Analog Outputs: Two isolated 4-20 mA analog outputs are standard, with an option for a third output if required. The default setting provides analog outputs for chlorine and pH.
  8. PID Control Function: The monitor has a standard PID control function that can be assigned to one analog output.
  9. Digital Communication Options: The monitor supports digital communication options such as Profibus DP, Modbus RTU, or Ethernet IP.
  10. Relay Outputs: Three SPDT (Single Pole, Double Throw) relays are standard, with programmable functions for alarm, control, or trouble indication. An option for three additional low-power relays is available.
  11. Enclosure: The monitor comes in a NEMA 4X (IP-66) enclosure suitable for wall, pipe, or panel mounting.
  12. Display: The back-lit large LCD display provides clear visibility in any lighting conditions. A scrolling second line on the display offers additional information and programming prompts.

Applications for the Q46H/62-63 Residual Chlorine Monitor include:

  • Potable water systems
  • Water reuse systems
  • Cooling towers
  • Aquariums
  • Wastewater treatment effluents

The monitor is designed to meet the water quality monitoring needs of these applications, providing accurate and reliable measurement of residual chlorine levels.
