Application of Dacai UART screen in air detector [Copy link]

Over the years, while the local economy has developed rapidly, various regions have continued to experience varying degrees of environmental pollution incidents such as water, air, and noise, which have seriously affected people's quality of life and hindered the sustainable development of the local economy. Environmental protection monitoring comes first, and automation and informatization are the premise and guarantee for good environmental monitoring. Portable air quality monitoring equipment is more convenient and quick for multi-point urban mobile environment monitoring, emergency air quality monitoring after emergency handling, and irregular spot checks of key polluting enterprises.

• Introduction to air detector

The air detector is independently developed and produced. It is a latest technological product developed based on the principle of constant potential electrolytic sensor to detect polluted gas and the principle of light scattering to detect dust. It is combined with internationally mature electronic technology and network communication technology.

2. System composition

Atmospheric pollutant parameters: sulfur dioxide, nitrogen dioxide, inhalable particulate matter PM10 (expandable parameters: H2S, CO, O3, HF and other toxic gases) On-site calibration equipment, in order to ensure the accuracy of the instrument, the instrument needs to be calibrated regularly for zero point and range. It is necessary to equip a set of high-precision gas distributor, standard gas, zero gas or zero gas generator; host computer software (optional) The historical data of the portable monitor can be exported and transferred to the computer via USB. The host computer software completes statistical reports, data analysis, curve making, printing and other functions.

• How air detectors work

Adopting the principle of high-sensitivity electrochemical sensor, combined with single-chip technology and network communication technology, it can continuously monitor SO2, NO2, O3, CO, H2S, NH3, HF gases in the atmosphere and fully display the required measurement data.
