Description / ATI Q45H/64 with Flowcell
The Q45H/64 Dissolved Ozone Meter is the ideal choice when accurate dissolved ozone levels are required to be displayed locally via an LCD display, or remotely via a 4-20 mA output. The Q45 system offers all the same sensor and range features as the Q46 system but without the integrated PID loop, relay control, or multiple 4-20 mA outputs.

Sensor & Flowcell:
| Constant Head Flowcell
This Q45H/65 is confgured with the Constant Head Flowcell for consistant performance. The Q45H/64 provides the best performance when used with the constant-head flowcell. Water pressure on the sensor and water flow are automatically controlled via the gravity flow chambers in the flowcell. Water flows of 400 - 500 cc/min will be used. |
 |
Calibration:
The Q45H Ozone Sensors must be calibrated on-site with the customers' water in process. As pressure and water flow will affect the calibration it is important to perform the calibration in the specific process the sensor will be used to measure ozone in.
Calibration frequency will depend upon ozone concentration in the water and water quality. Higher dissolved ozone levels will consume the electrolyte solution and membrane quality quicker than low levels of ozone. At ozone levels below 2.0 ppm we find the Q45H can maintain stable readings for 6-months at a time between calibrations. However, at ozone levels greater than 20 ppm calibration should be performed at least monthly and ozone levels greater than 100 ppm will require weekly or even daily calibration.
A bottle of electrolyte solution and a pack of 10 membranes are shipped with each Q45H Dissolved Ozone Meter.
Calibration should be performed with a colorimetric dissolved ozone test kit. Below are a few kits we suggest and the potential applications for each.
I-2022 SAM Dissolved Ozone Meter
Best for low level detection of ozone, below 0.75 ppm
I-2019 SAM Dissolved Ozone Meter
Best for high level detection of ozone, direct read to 5.0 ppm
K-7404 Dissolved Ozone Kit
Low cost option to measure ozone from 0 - 3.0 ppm

Ozone Electrolyte Solution
Interference-Free Dissolved Ozone Measurement
Q45H/64 monitors use a polarographic membrane sensor to accurately measure Ozone in water. The sensor operates much like a battery, generating current that is linearly proportional to the concentration of chlorine dioxide in solution. An Ozone permeable membrane isolates the sensor from the measured sample and insures that the measurement is interference free.
Two versions of the sensor are available, a sensor intended for installation in a flowcell and a sensor intended for submersion applications. Requiring minimal maintenance, sensors are easy to use and easy to maintain. An integral RTD provides temperature compensation and allows temperature to be displayed and transmitted from the monitor.
Sensor Stabilization
Ozone sensors require 2 to 4 hours of stabilization time when first installed or after membrane change. ATI offers a battery powered polarizer that can be used to stabilize a spare sensor so it is ready to run within a few minutes of installation. Polarizers simply plug into the sensor connector and require no adjustments.
Sensor Polarizer can be added to the Q45H in the options section above. Separate polarizers are available for the submersion and flowcell style sensors.

Monitor and Flowcell Mounting

Constant Head Flowcell
The Constant Head Flowcell is the best option for accurate and repeatable dissolved ozone measurements. Water will flow through the flowcell at a rate of 400-500 cc/min (0.4 - 0.5 LPM). Water flow must be regulated with an upstream needle valve or flow restrictor. Water will flow through the flowcell under gravity and flow to drain. Ensure the drain line is 3/8" ID or larger and flows downhill to a drain, or, back into the process water tank under gravity,.

Panel Mounting
The Q45H/64 monitor can be panel-mounted onto your control box for a clean and professional look. An optional Panel Mount kit is available that can be added when purchasing.
