In this season, viral colds are a serious problem. Various coughs often occur and are quite severe. Many children cannot spit due to their young age, so they always cannot spit out phlegm, and the phlegm goes up and down in the throat, causing breathing difficulties and even continuous coughing. When nebulizing, you need to pay attention to what size of nebulizer particles is the best and what is the main purpose of nebulization? The atomized particle measuring instrument is based on the Mie scattering theory and is currently the most advanced and popular testing method. Its measurement accuracy is much higher than traditional testing methods. The particle measuring instrument is fully controlled by a microcomputer and can automatically complete functions such as data collection, analysis and processing, result storage, and printing. It is easy to operate and has a high degree of automation. The typical measurement time of the aerosol particle measuring instrument is less than 60 seconds (excluding sample preparation time). High-precision circuit design can continuously sample multiple times in one test, improving the repeatability of the instrument. The test software of the atomized particle measuring instrument runs under the Windows operating system. It is simple and intuitive to operate, powerful in function, and has rich report output content. It also provides Chinese and English versions of the test software for user convenience. The sample of the atomized particle measuring instrument is heated in the atomizing cup and begins to volatilize. The volatile gas condenses on the glass plate or aluminum foil that has been cooled by the cooling chamber. After the condensation process is completed, remove the glass plate or aluminum foil, measure the atomization value or weight of the condensed components on the glass plate or aluminum foil, and compare it with the data before condensation to obtain the atomization and volatilization characteristics of the sample. Glossiness method of atomized particle measuring instrument: When the sample is heated in the fogging cup, the gas evaporated condenses on the low-temperature glass plate. By comparing and calculating the glossiness value of the glass plate before and after condensation, the fogging value of the sample can be obtained. Haze method: When the sample is heated in a fogging cup, the evaporated gas condenses on a low-temperature glass plate. By comparing and calculating the haze values of the glass plate before and after condensation, the haze value of the sample can be obtained. Gravimetric method: When the sample is heated in the fogging cup, the evaporated gas condenses on the low-temperature aluminum foil. By weighing the weight change of the aluminum foil before and after condensation, the weight of the sample atomization-condensation can be obtained. Main features of atomized particle measuring instrument 1. Direct reading of particulate matter mass concentration (mg/m3) is possible, and the result can be obtained in 1 minute, or the sampling time can be set arbitrarily according to user needs; 2. Fast and accurate measurement with high detection sensitivity; 3. A self-calibration system is designed, and the instrument performance is stable and reliable; 4. It has air curtain shielding and clean air self-cleaning functions to ensure that the optical system is not contaminated; 5. Realized automatic zeroing of software; 6. It has two-way communication function with computer, and can process data through PC and print out curves and tables; 7. It has multiple functions such as continuous monitoring of particle concentration, timed sampling and alarm for excessive dust concentration; |
