Help center – Airthereal - Ozone Generators

When the air fluctuates and the particles move, the dust sensor in the unit will detect this change and reflect it by number on the control panel. For example, if you walk around the unit, the reading will change as the air fluctuates. If you still have concerns, you can do a test to check whether the dust sensor is working properly. You can spray perfume towards the dust sensor to see whether ...

Measurement of Ozone Production Sensor

of Ozone Production Sensor (MOPS), measures directly the rate of ozone production in the atmosphere. The sensor con-sists of two environmental chambers made of UV- transmitting Teflon film, a unit to convert NO 2 to O3, and a modified ozone monitor. In the sample chamber, flowing am-bient air is exposed to the sunlight so that ozone is produced just as it is in the atmosphere. In the ...

As cofactors of sensor performance such as temperature (T) and relative humidity (RH) potentially influence the response of NO 2 and O 3 sensors, corrections for cofactors were made by using T, RH, and the sensor measurements to predict measurements made by NO 2mon and O 3mon during the first co-location period (training dataset). The developed models were tested in the merged data obtained ...

Measuring O3 Output - Ozone Solutions

A small deviation in actual flow measurement will result in a large error in the resulting ozone output figure. Since this is such an important value, we recommend using a high quality Mass Flow Meter to measure the total gas flow entering the ozone generator. A mass flow meter will measure total gas flow.

Gas Sensors Ozone -

Ozone is a triatomic form of oxygen, meaning that the molecule, ozone, is made up of 3 oxygen atoms. Unlike oxygen, ozone is a visible gas with a light blue color at very high concentrations. At low concentrations ozone is colorless. Ozone also has a distinct odor that is noticeable at very low levels and may be associated with a “clean” smell, at higher levels ozone has a very pungent odor. Ozone is an unstable gas that readily decomposes to oxygen naturally. Ozone …
