As we all know, the ozone detector is the 1 gas detection instrument used to detect the concentration of ozone content. By using the principle of ultraviolet absorption method, a stable ultraviolet lamp light source is used to generate ultraviolet light, and a light wave filter is used to filter out other wavelengths of ultraviolet light, only allowing the wavelength of 253.7nm to pass. After the sample photoelectric sensor, and then through the ozone absorption cell, to reach the sampling photoelectric sensor. By comparing the electrical signals of the sample photoelectric sensor and the sampling photoelectric sensor, and then through the calculation of the mathematical model, the ozone concentration can be obtained. However, if we want to obtain a relatively accurate detection effect, we should also pay attention to related matters when using it. So what should we pay attention to when using the ozone detector? The following is an introduction by Yiyuntian:

Precautions for using ozone detector:

1. The receptor point or a densely populated place, that is, the location where ozone gas can pose a threat to personnel. The main purpose of this is to protect the safety of personnel.

2. the leak point or detection point is the location where ozone gas exists. the closer the better, because ozone is chemically active and easily decomposed.

3. the installation height of the ozone detector should be lower than the leak point, because the molecular weight of ozone is larger than that of air, and ozone will spread below the leak point.

4. if the gas detector has not been used for a long time (more than 1 week), let the instrument run for a period of time (more than 10 minutes) after starting up, enter the setting mode, and observe whether the zero point of the instrument is stable at about 0. if it is not zero or the drift is large, it needs to return to zero point (oxygen detector is the target point).

5. after the instrument is tested, please wait for the value to drop before turning off the power supply. before returning to zero, please also wait for the value to drop and stabilize before operating.

To sum up, it is the precautions for the use of the ozone detector. The ozone detector can be used in ozone preparation workshop (ozone generator, ozone workshop, etc.), chemical industry, petroleum, paper making, textile and flavor industry, water treatment, food and medicine sterilization workshop and other occasions, so as to detect the presence of high and low concentrations of ozone gas to ensure personal safety.
