what are negative ions

1.Product introduction of what are negative ions

what are negative ions are molecules floating in the air or atmosphere, gas molecules or atoms with one or more electrons, usually in a negatively charged state.Shandong Fengtu Internet of Things Technology Co., Ltd., as an enterprise specializing in the research, development, production and sales of micro meteorological instruments, has been committed to the promotion and application of micro meteorological instruments and meteorological environment solutions.With a complete production chain, a strong technical team and a comprehensive marketing team, the five-element micro-meteorometers, six-element micro-meteorometers, small automatic weather stations and other meteorological products we develop and produce have been widely used in meteorological monitoring, urban environment In the fields of monitoring, wind power generation, navigation ships, aviation airports, bridges and tunnels, etc., we have customers all over the country and have achieved good social and economic benefits.

what are negative ions innovatively realizes negative oxygen ions, air temperature, humidity, PM2.5, PM10 and other meteorological elements through a highly integrated structure, which can realize 24-hour continuous online monitoring of outdoor meteorological parameters through a digital communication interface Output five parameters to the user at once.

2.Product features of what are negative ions

1.Strong anti-interference ability, with watchdog circuit and automatic reset function to ensure stable operation of the system

2.High integration, no moving parts, zero wear and tear

3.Maintenance-free, no on-site calibration required

4.The use of ASA engineering plastics for outdoor applications does not discolor all year round.

5.The standard output signal of product design is RS485 communication interface (MODBUS protocol); optional 232, USB, and Ethernet interfaces support real-time reading of data☆

6.Optional wireless transmission module, minimum transmission interval is 1 minute

7.The probe is a snap-on design, which solves the problem of looseness and inaccurateness during transportation and installation☆
