Accurate dissolved ozone measurement is essential in water treatment, ozone disinfection, and industrial processes where ozone levels need to be monitored and controlled. A used Q46 Dissolved Ozone Monitor with Flowcell provides a practical, cost-effective solution for continuous ozone monitoring in water.
The Q46 supports multiple measurement ranges, from 0–200 ppb to 0–200 ppm, with resolution as low as 1 ppb on the lowest range. The system combines a membrane-covered polarographic ozone sensor with a constant-head flowcell designed to provide controlled and consistent sample flow.
Key Features
- 0–200 ppb to 0–200 ppm measurement ranges
- Resolution down to 1 ppb
- Membrane-covered polarographic ozone sensor
- Constant-head flowcell
- Two isolated 4–20 mA outputs
- Three adjustable relay outputs
- Integrated PID control
- Backlit LCD display
- NEMA 4X / IP66 enclosure
- Wall or pipe mounting
Applications
The Q46 can be used for water and wastewater treatment, ozone disinfection, industrial water systems, ozone generation, and research applications. Its analog outputs and relay controls also allow integration with larger monitoring and process-control systems.
Why Consider Used Equipment?
A used Q46 can be an economical alternative to new monitoring equipment for facilities replacing an existing system, expanding monitoring capabilities, or setting up an ozone treatment process.
When purchasing used equipment, it is important to verify the instrument’s condition, sensor status, calibration requirements, and included components.
Conclusion
The Q46 Dissolved Ozone Monitor with Flowcell combines flexible measurement ranges, continuous monitoring, and process-control capabilities in a compact system. For applications requiring reliable dissolved ozone measurement, a properly inspected and maintained used Q46 can be a practical and cost-effective option.
