PM2.5: also known as aerosols PM2.5, refers to the atmosphere of ultra-fine suspended diameter less than or equal to 2.5 microns (um) particles, also known as particulate matter into the lungs. Scientists expressed PM2.5 per cubic meter of air content of such particles, the higher the value, on behalf of the more serious air pollution.
Although the Earth's atmospheric composition PM2.5 only a few components in the content, visibility and air quality but it has important influence. Compared with coarse atmospheric particulate matter, PM2.5 particle size is small, rich in a lot of toxic and hazardous substances and long residence time in the atmosphere, transmission distance, and thus on human health (heart disease, arteriosclerosis, cancer, greater asthma and chronic bronchitis) and air quality (haze) in. Foggy day lead to poor atmospheric dispersion of pollutants can not be diluted, thus exacerbated popular respiratory symptoms.
CEM DT-9880/9881 series particle counter can simultaneously measure and display 6 channel 0.3 / 0.5 / 1.0 / 2.5 / 5 / 10um particle size thereof, etc.
1. When measuring particulate matter, according to F1, F2, F3, etc. keys to enter the corresponding camera, video recording and Settings page. You can set the duration of the sample (used to control the volume of the sample gas), particle size and display alarm, temperature and humidity display, counting mode.
2.HCHO, CO measurement (only DT-9881) under the set model for measuring time, alarm values, maximum and minimum, average, difference, ambient temperature and humidity, dew point, wet bulb temperature can be set.
3. The file browser to view stored data, image or video information, these documents are to save time was named.
4. System setup menu to set the date and time, font color, backlight brightness, auto-off time, the screen saver settings, file storage location, temperature unit switching to restore the factory settings.
1. Home personal domain
airborne particulates present in various forms, from the dander, plant pollen and airborne bacteria animals, glass fibers, asbestos, and combustion particles. In the case of stationary, a person will fall off every minute for up to 500,000 particles of sebum (≥0.3μm); in the active state, you can achieve a sebum 45,000,000 particles per minute. Humidity and temperature generation rate of these pollutants affect very large. Therefore, we recommend that each family to configure a DT-9880/9881 particle counter, monitoring and decontamination PM2.5 and other ultrafine particles produced from the source, but also to monitor the indoor temperature and humidity inside the vehicle air conditioning
2. The production areas of
bio-pharmaceutical engineering, food production and preservation, precision machinery production and other industries require stringent clean working conditions, while the temperature and humidity, there are strict requirements. In addition to production, in transportation and warehousing and other sectors also need strict air quality monitoring and control. Such as dew point temperature measuring mode can help staff quickly find humid warehouse area so you can make informed decisions and avoid product subject to mildew, moisture and other negative factors. DT-9880/9881 6-channel particle counter set particles, air temperature and humidity, dew point temperature, toxic gas monitoring in one, your best tool is the perfect solution
3. The research field of environmental protection
CEM DT-9880/9881 to play an extremely important role in airborne dust particles, temperature and humidity, toxic gases and other environmental indicators for monitoring the process.
"National Environmental Protection" second five "plan" to carry out the requirements of ozone, PM2.5 and other pollutants in Beijing, Tianjin, the Yangtze River Delta and Pearl River Delta region and other areas to carry out a joint inspection of law enforcement, in 2015, said the regional air pollution to obtain compound control environment of all urban air quality at or better than the national secondary standard, acid rain, haze and photochemical smog significantly reduced. Compared with the international "air quality standards", we have a long way to go
