Top 5 Ozone sensor functions

Summarize?

We all know that the chemical properties of ozone are extremely active. Its energy when it is free produces strong oxidation in an instant, which can sterilize, disinfect and detoxify. It is widely used in water plant sterilization and disinfection, tableware disinfection, indoor air purification, fruit, and vegetable preservation, there are also medical treatments, etc. But if the concentration of ozone is too high, it will cause great harm to human health. Therefore, whether it is to use the strong oxidizing property of ozone or prevent its harmfulness, it is inseparable from the monitoring of ozone concentration. Ozone sensor is the most effective method to detect ozone concentration.

What is an ozone gas sensor?

An ozone sensor is a device that converts information such as the composition and concentration of ozone gas in the environment into information that can be used by personnel, instruments, computers, etc.

Principle of ozone meter

According to different detection principles, ozone meters can generally be divided into three types: ultraviolet, semiconductor, and electrochemistry:

6 types of ozone meters suitable for different places1. Wireless ozone meter

Usually, not only one element is measured for use in the home environment, but several important air quality elements are concentrated on one device for measurement. Just like this DM502-O3 air quality detector, it can not only measure indoor ozone concentration but also measure TVOC, PM2.5, PM10, temperature and humidity at the same time.

This air quality monitor has a built-in fan to quickly draw in ambient air to allow REAL-TIME measurements. It incorporates a laser sensor to measure levels of dust particles and has a second electrochemical semiconductor sensor to measure formaldehyde and natural/synthetic organic compound levels. The air monitor also auto-calibrates.

2. Wall-mounted ozone meter

What characteristics should an ozone sensor in an industrial environment have? Of course, the protection level is high, the measurement is sensitive, and remote unified monitoring is possible. This wall-mounted ozone sensor is a typical industrial gas sensor.

This wall-mounted ozone sensor adopts the electrochemical detection principle, by measuring the current generated when the target gas enters the sensor and the chemical reaction occurs at the sensing electrode, so as to achieve the purpose of detecting its concentration. The reaction is rapid and sensitive, and the ozone concentration can be reliably detected. The shell adopts a wall-mounted waterproof shell, which is easy to install and has a high degree of protection; the equipment adopts a high-sensitivity gas detection probe imported from the United States and uses a high-performance signal acquisition circuit, which can accurately measure the ppm ozone concentration, with stable signals and high accuracy.

The equipment adopts 485 communication, standard Modbus-RTU communication protocol, communication address, and baud rate can be set, and the farthest communication distance is 2000 meters. The equipment has a 10-30V wide-voltage power supply, and the enclosure has a high degree of protection, which can adapt to various harsh conditions on-site.

3. Portable ozone meter

For professional gas safety inspection personnel, a portable ozone detector is essential. There are two types of portable ozone detectors: pumping type and diffusion type, which can be selected according to your needs. The portable ozone detector is designed to safely protect human life. It is small and lightweight and can be easily clipped in a belt, shirt pocket, or helmet to detect the concentration of ozone gas exposed to extreme environments. If the gas concentration of the detector in the air is too high, the ozone detector will send out a triple alarm signal of sound, light, and vibration at the first time, thereby effectively preventing the accident of poisoning caused by the excessive concentration of ozone gas in the air.

4. Fixed ozone meter

The fixed ozone meter is used for 24-hour online monitoring of the gas concentration in the environment or pipelines and alarms. On-site display of concentration and sound and light alarm, remote data transmission. This is a detector that is used more in industrial equipment and in the production process. It can be installed at a specific detection point to detect specific gas leaks. When in use, it should be selected according to the type and concentration of the gas on-site, and at the same time, attention should be paid to installing them in the most likely leaking part of the specific gas. For example, the most effective height of the sensor should be selected according to the specific gravity of the gas.

The fixed ozone meter is composed of a gas detection alarm controller and a fixed ozone detector. The gas detection alarm controller can be placed in the working room to monitor and control each monitoring point. The ozone detector is installed in the place where the gas is most likely to leak., The core component is the gas sensor. Fixed ozone detection alarms are widely used in petroleum, chemical, metallurgical, electric power, coal, tap water, and other environments, and play an important role in natural gas protection.

5. Duct type ozone meter

The duct-mounted ozone meter is specially designed for plug-in pipeline gas measurement. It adopts a plug-in structure combining a stainless steel air duct and a stainless steel flange, and a professional ozone concentration sensor probe is used as the core detection device. The transmitter adopts electrochemical technology for O3 concentration measurement, and the response is rapid and sensitive, and the ozone concentration can be reliably detected. The transmitter is professionally used in pipeline ozone concentration measurement. The equipment adopts waterproof housing design, pipeline installation method, convenient on-site installation, and anti-interference circuit design, which can withstand various strong electromagnetic interferences such as on-site inverters.
