Semiconductor O3 gas sensor Introduction
Semiconductor O3 gas sensor is made of solid metal oxide gas sensitive semiconductor materials. The semiconductor O3 gas sensor is mainly used to detect the gas concentration of ozone. Ozone sensor is sensitive to ozone, chlorine gas, nitrogen dioxide and other strong oxidizing gases also have a certain sensitivity. With low cost, simple manufacturing, high sensitivity, fast response, long life, long-term stability, simple test circuit and so on. Ozone sensor is widely used to detect ozone concentration in household and atmospheric environment.
Semiconductor O3 gas sensor Features
1, the machine is small in size, light in weight, easy to install, can be mounted in portable, fixed, pipe type and other appearance sensors used.
2, stainless steel protective net, high protection, easy to clean effective protection from particulate matter and impurities, easy to maintain and use.
3, high-performance chip, breakthrough manufacturing process, product performance significantly improved.
4, long service life, low cost, simple driving circuit.
5, high resolution, high sensitivity, fast response speed, strong anti-interference force.
Semiconductor O3 gas sensor Parameters

1. Avoid exposure to volatile silica vapors.
2, avoid sensor exposure to high concentration of corrosive gas.
3, avoid alkali, alkali metal salt, halogen pollution.
4, avoid the sensor contact with water or immersed in water, easy to cause the sensor sensitivity characteristics decline.
5, avoid applying too high voltage, if the voltage applied to the sensor heating is higher than the specified value, even if the sensor has not received physical damage or damage, it will cause damage to the lead/or heater, and cause the sensor sensitive characteristics to decline.
Why do we need to detect ozone?
Ozone is a well-known gas. Ozone is often present in the atmosphere, helping to filter harmful rays from the sun and allowing the earth’s organisms to thrive. In the medical field, ozone can also be used for disinfection. In the state of pure ozone, it can carry out effective disinfection and sterilization, but it must be cleaned up afterward to avoid pollution. Inhalation of ozone in a small amount is beneficial to the human body, but a large amount of inhalation will be harmful to the human body and will be chemically converted into VOC pollutants at a specific temperature. Ozone treatment and detection have also become one of the key tests of environmental protection.
What is an o3 sensor?
An o3 sensor is an electronic device used to monitor the concentration of ozone in the air. The built-in ozone detection module converts the ozone concentration into an electrical signal and outputs it.
What types of ozone sensors are there?
According to different places of use, our company provides four kinds of ozone sensors: home ozone monitor, portable ozone detector, duct type ozone detector, and fixed ozone detector.
