When it comes to accurately measuring dissolved ozone levels, the Q45H/64 Dissolved Ozone Meter stands out as the ideal choice. Whether you need to display levels locally on an LCD screen or transmit data remotely via a 4-20 mA output, this device delivers reliable performance without the complexity of integrated PID loops, relay controls, or multiple 4-20 mA outputs.
Versatile and User-Friendly Ranges
The Q45H/64 offers four user-settable ranges, providing flexibility to meet various application needs:
- 0-200 ppb (1 ppb resolution)
- 0-2.000 ppm (0.001 ppm resolution)
- 0-20.00 ppm (0.01 ppm resolution)
- 0-200.0 ppm (0.1 ppm resolution)
These ranges can be easily adjusted using the display panel on the Q45, making the device adaptable to a wide array of scenarios.

Robust and Flexible Design
The Q45H/64 is built to withstand challenging environments, with a NEMA 4X (IP-66) enclosure that ensures durability and flexibility in mounting options—whether wall, pipe, or panel. The backlit LCD display ensures clear visibility in various lighting conditions, with a scrolling second line providing additional information and programming prompts.
Sensor and Flowcell Options
- Sealed Flowcell: Ideal for controlled water flow applications, ensuring stable readings with slight pressure.
- Constant Head Flowcell: Best for low-level ozone monitoring (below 0.5 ppm), automatically controlling water pressure and flow.
- Low-Flow Flowcell: Suitable for applications requiring minimal water usage, maintaining sample water flow rates of 150–300 cc/min.
- Flowcell Sensor: Versatile sensor compatible with various flowcell systems.
- Submersion Sensor: Designed for submersible applications, ideal for tank water measurements.
Easy Calibration and Maintenance
Calibration of the Q45H/64 is performed on-site, ensuring accuracy within your specific process environment. The frequency of calibration depends on ozone concentration and water quality, with recommended intervals ranging from six months for low levels to weekly for higher concentrations.
The system comes with a package of membranes, a 120 cc bottle of electrolyte, and a spare parts kit, making maintenance straightforward and cost-effective.
Calibration Kits
To ensure precise calibration, we recommend using colorimetric dissolved ozone test kits:
- I-2022 SAM Dissolved Ozone Meter: Best for low-level detection below 0.75 ppm.
- I-2019 SAM Dissolved Ozone Meter: Direct read to 5.0 ppm for higher level detection.
- K-7404 Dissolved Ozone Kit: A cost-effective option for measuring ozone from 0-3.0 ppm.
Interference-Free Measurement
Using a polarographic membrane sensor, the Q45H/64 provides interference-free ozone measurements in water. The sensor’s design ensures minimal maintenance, with an integral RTD for temperature compensation.
Sensor Stabilization
Ozone sensors require 2 to 4 hours of stabilization after installation or membrane change. ATI offers a battery-powered polarizer to pre-stabilize a spare sensor, ensuring it is ready for immediate use.
Conclusion
The Q45H/64 Dissolved Ozone Meter is a powerful, versatile tool for accurate ozone measurement in water. Its user-friendly interface, robust design, and flexible mounting options make it an ideal choice for various applications. For precise and reliable ozone monitoring, the Q45H/64 is your go-to solution.
