Ozone (O3) Sensor 50 PPM
Ozone O3 Sensor
Qsafe provides best-in-class electrochemical Ozone O3 sensor and monitoring systems that can be used to precisely and accurately determine the concentration of ozone in the area. Monitoring is the primary shield against ozone’s ill effect on our health. Electrochemical sensors are the industry standard for monitoring ozone. In this type of sensor electric current produced by the reaction of the gas sample with the electrolyte is measured to determine the concentration of ozone in the air. The direction of flow of the electron created an electric current which is proportional to the concentration of gas.
NO2 gas usually gets in the air from the burning of fuel like emissions from cars, buses, trucks, factories, etc. Its presence in the air contributes to forming of air pollutants. This is a very harmful gas that can cause respiratory infections and asthma, even reducing crop yields of agricultural activities.
Ozone is a layer present in the stratosphere of the atmosphere. Ozone is a protective layer that protects from the harmful ultraviolet radiation coming into earth. However, the ozone layer that we breathe at ground level is hazardous. Ozone gas consists of three atoms of oxygen, colorless to pale blue in color. The odor of ozone is pungent and highly combustible. The major source of ozone presence at ground level is ozone layer breaking. Other source includes automobile emissions, construction, power plants, extraction and operation of oil, industrial boilers, chemical plants, coal, and gasoline burning. Its monitoring not only helps in determining air quality but also to warn if there is a high quantity where it should not have been.
What Does Our Ozone Sensor Have?
Compact
The compactness of the sensor allows its use in stationary devices as well as handheld mobile devices.
Durable
The ozone sensor comes with 10 years of operational life.
Highly Responsive
The sensor is highly responsive and gives a response in less than 15 seconds.
Energy Efficient
The demand for energy by the sensor is very low (0 mW at 0 mV bias). This decreases the overall consumption of energy.
Individual Calibrated
Calibration is done individually for devices with sensors to give the highest accuracy.
RoHS Compliant
The compliance of the sensor against ROHS (Restriction of Hazardous Substances) explains no use of toxic/ hazardous materials in the making of sensors.
What technology is being used in Ozone Sensor?
Ozone sensors provided by Qsafe work on electrochemical gas sensing techniques. The technique uses three principle components a working electrode, a counter electrode, and an ion conductor. The ion conductor is a bridge between two electrodes. The passing of gas through the senor results in the current generation between electrodes and this generated current is directly proportional to the concentration of Ozone in the environment.
The directional flow of electrons through the wire creates an electric current that is directly proportional to the concentration of gas. The gas sensor works by measuring this current flow between the two sensors.
Sensor Calibration
The sensor calibration determines the instrumental accuracy and measurement traceability. The comparison of standard measurement with instrumental measurement is calibration. The sensor is exposed to O3 in the range of interest and the NIST standard is used for reference. Standard environmental conditions like 23 + 3oC temperature, 50 + 15% relative humidity, 0.9-1.1atm pressure and air velocity of 0.05m/s were used during calibration.
