AV88 Ozone Monitor and Sensor Kit

The AV88 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 AV88 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 is shipped with each AV88 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.

Best for high level detection of ozone, direct read to 5.0 ppm

When measuring ozone levels above 0.75 the I-2019 dissolved ozone meter is the best option.  This is a digital handheld ozone meter using the DPD method of measuring ozone in water.  Simple manual grab-sample vacu-vials are used to indicate ozone levels in water.

The I-2019 will measure ozone in water directly up to 5.0 ppm (highest of any packaged ozone test kits) and can be diluted with the sample cup to read ozone levels up to 25 ppm with reasonable accuracy.

Low cost option to measure ozone from 0 - 3.0 ppm

The K-7404 kit is a lower cost, visual indication option for calibrating the dissolved ozone meters.  The same DPD measurement principle as the I-2019 test kit is used, with a simple color comparator to use to visually indicate ozone levels in water.  Two comparators are provided, one to indicate ozone levels from 0-0.6 ppm, and another with a range of 0.6 - 3.0 ppm.
