The OZ-20 Ozone meter is for dissolved ozone measurement in water. The OZ-30 Ozone meter is for measurement of ozone in a gas phase.
These units use a polarographic membrane type technique for measuring so that reagents are not required for analysis.
Ozone is used primarily for disinfection purposes and the concentration needs to be accurately measured and monitored since it is considered a hazardous material.
These meters can be field operated. The LCD display shows all appropriate parameters and an easy to follow calibration procedure. Calibration is generally done by air or iodine titration.
