Function of negative ion concentration detector
When we understand its function, we must first understand the role of negative oxygen ions: negative oxygen ions, also known as "air vitamins." When air is affected by external conditions, some air molecules will release electrons. Under normal circumstances, the released electrons quickly combine with neutral molecules (such as oxygen molecules and water molecules) in the air to become negative air ions, also known as negative oxygen ions. The World Health Organization stipulates that when the number of negative oxygen ions in the air reaches more than 0/000 per cubic centimeter/kloc-0, the standard of "fresh air" is reached. However, the measured values of several measuring points in Zhushan National Forest Park have reached a low value of 165 1 and a high value of131per cubic centimeter, with an average of 1800 per cubic centimeter.

The benefits of negative oxygen ions in improving cardiac function, myocardial nutrition, lowering blood pressure and restoring the health of patients with cardiovascular and cerebrovascular diseases. It can improve the vitality of independent life, improve endocrine function, treat diseases and protect health. The installation and publicity of the automatic negative oxygen ion detector can let the public know the local negative oxygen ion concentration at any time and quantify the invisible and intangible things. It can not only popularize scientific knowledge, but also stimulate people's interest, guide the public to transit in the forest frequently, and bathe in the "forest", so that tourists can not only learn about Zhu Xiao Scenic Area on the level of tourism and vacation, but also be an excellent place for people to maintain health and relax.

Therefore, we use the negative ion concentration detector to detect the local concentration and determine whether it is suitable for human habitation or beneficial to human body.
