Ozone Monitor in ambient

For OZONE detection in air purifying, deodorizing, sterilization and environmental monitoring systems

 The PIE Ozonation monitor model OZ-06-A is an on-line monitoring system designed for continuous measurement of ozone gas in ambient. OZ-06-A equipped with a semiconductor ozone sensor using an innovative ITO (Indium Tin Oxide) sensing material for ozone detection. The full-scale operating range of the monitor is 0 – 255 ppb. Relay contacts are standard, and may be used either for simple control schemes or for signaling ozone leakage.

Typical Applications


Ozone Gas Concentration Control in room sterilization

Ozone leakage monitoring for ozone generator

Ozone dosage monitoring in water treatment

Ozone Monitor Model: OZ-06-A

Sensitivity Characteristics

 A semi-conductor ozone sensor measures gas by the value of Rs/R(air). This is called “sensitivity”. Thus, the gas ozone value is based on the sensor resistance value in clean air. Where:

Rs : Sensor resistance value in measuring the gas

R(air) : Sensor resistance value in clean air

The sensor resistance increases with an increase of ozone concentration based on logarithmic function.
