Product introduction:
Negative oxygen ion monitoring system is a monitoring station that automatically collects the air cleanliness index data in scenic spots and ecological parks (such as constructed wetlands, ecological scenic spots, botanical gardens, etc.) all day. It monitors the negative oxygen ion, air temperature, humidity, PM2.5 and other environmental quality parameters in scenic spots in real time through automatic monitoring equipment, and transmits the monitoring data to the network monitoring software platform through GPRS, Internet and other means, After the systematic processing of the software platform, it can be displayed to users intuitively and quickly through the LED display screen

Functional features:
1) Cylindrical capacitor air collector and advanced negative pressure dust removal structure not only have strong stability, but also can ensure long-term operation in harsh environment.
2) The cylinder capacitor air collector has excellent electrostatic shielding function, which can better overcome the adverse effect of static electricity on measurement.
3) Airflow buffering technology avoids the influence of spiral airflow on measurement.
4) It is made of metal materials with super moisture resistance, which ensures normal operation without frost and dew in high humidity environment.
5) Built in advanced amplification circuit can detect the number of negative ions with high sensitivity.
6) It has an automatic working mode without manual processing. It works automatically when powered on. It can be measured continuously and one data per second.
