- Utilizes a membrane-covered polarographic sensor that does not require the addition of chemical reagents
- Contact outputs include two programmable control relays for control and alarm modes
- Easy integration with NexSens data logging & telemetry products
The residual chlorine sensors are available in two configurations: flowcell and submersion. The Free Chlorine sensor should always be used in the flowcell configuration. The Constant-Head Flowcell is used to maintain a constant flow rate and pressure at the face of the sensor. The only requirement is that the sample inlet flow rate be at least 7 gallons per hour. A Low Volume Flowcell is available for clean water application with a flow rate of 1-3 gallons per hour. The Combined Chlorine sensor can be used in either the Flowcell or Submersion configuration. The submersion sensors require flow velocities of at least 0.4 ft/sec for proper operation.
When the pH of the water stream varies regularly, a significant error in free chlorine concentration is introduced. With the simple addition of an optional pH sensor, the Q45H will automatically correct for these changes up to a pH of 9. With AC version, this option provides a second analog output that can be assigned to pH or temperature, converting the chlorine monitor into a dual parameter system. Both Free and Combined Chlorine monitors can be converted to dual output monitors.
This line of microprocessor based instrumentation allows for easy implementation as a loop-powered transmitter, line powered analyzer, or portable battery powered unit within the same instrument.
NexSens data logging and telemetry systems integrate easily with ATI process monitors and sensors, providing real-time remote data readings, alarm notifications, and powerful data processing and reporting capabilities.
