Beijing Tianzheng Renhe tells you to pay attention to the following two points when purchasing a negative ion detector:
An anion grading standard company in accordance with the provisions of the World Health Organization, and referring to the common grading standards in Japan and other regions at home and abroad, has developed a corporate anion (mobility 1.0 ~ 0.4) grading standards, please refer to the following table:
Note: The concentration of negative ions can be as high as 10,000 ～ 50,000 (pieces / cm3) due to the strong shearing effect of the water flow close to the waterfall.
The application field of the negative ion detector is mainly used in environmental meteorology, ecological meteorology, tourism meteorology and other disciplines. Through the establishment of the negative ion monitoring network, from the perspective of ecological meteorology and tourism meteorology, we carried out research on the distribution characteristics of small particle size negative ion concentration at different time and space scales, different underlying surfaces, different weather processes, and different seasons. The meteorological department uses the relationship between negative ion concentration and meteorological conditions to carry out forecast of negative ion concentration meteorological conditions in the air, which will greatly expand the meteorological service field and service content, and can produce greater social benefits and potential economic benefits. Environmental protection departments will use the relationship between negative ion concentration and atmospheric environment to monitor the urban ecological environment and indoor and outdoor air quality, which will have great practical significance.
At present, in the monitoring of ecological environment and air quality, the concentration of negative ions has become an indispensable important indicator. The systematic observation and forecast of negative ions in the atmosphere, as well as the broadcast of television and satellite TV programs, have been put on the agenda by the relevant departments of some provinces and cities.
Negative ion content (concentration) is more in tourist attractions, forest parks, beaches, waterfalls, etc. In addition to going to places of interest, tourists are increasingly going to scenic spots with high anion content (concentration) to accept air baths to absorb the "vitamins" in the air. Negative ion content (concentration) has become a major factor in attracting tourists.

In the office environment, if the display is placed too close, it is easy to have difficulty in focusing and reflecting light when looking at the display, which makes the eyes sour. If it is too far away, the body will lean forward and suffer from pain in the neck and lumbar spine. This series of problems do not conform to the hidden dangers of ergonomics, which will harm your health over time.
Kingstar professional display bracket, so that all this is no longer your trouble! It can adjust your monitor to any position suitable for you, far and near, high and low arbitrary adjustment, to maximize the adaptability of your monitor and mobile office needs.
