It is much more sensitive than a regular ozone meter as it employs a high-quality ozone sensor made in Switzerland which is 10 times more sensitive. Although ozone gas is used in many applications as a "sanitizing" agent, too much of it can be harmful as ozone is a reactive gas and a well-documented air pollutant and irritant. The California Ambient Air Quality Standard (CAAQS) for outdoor ...

Ozone and NO2 sensors | Details |

The ozone sensor voltage changes by mV for each 20ppb, while the NO2 sensor voltage changes by mV for each 20ppb change. Looking at the NO2 sensor. The output range is 0-3V. The minimum number of ADC steps needs to be 3000 mV/ mV = 13464 steps. It is quick to determine that a 12 bit ADC with 4096 steps is not capable of delivering this resolution.

ECC Ozonesonde - EN-SCI

When ozone enters the sensor, iodine is formed in the cathode half cell. The cell then converts the iodine to iodide, a process during which electrons flow in the cell’s external circuit. By measuring the electron flow (, the cell current) and the rate at which ozone enters the cell per unit time, ozone concentrations can be calculated.
