Product Details
outdoor online GPRS TVOC air quality monitor with GC-PID sensor for
Benzene, toluene, ethyl benzene, xylene, styrene
Description:
The system can monitor TVOC (aromatic hydrocarbons: benzene, toluene, ethylbenzene,
xylene, etc.;Ketone, halogenated hydrocarbons: trichloroethylene,
perchloroethylene and other 300 kinds of VOC gases) H2S,NH3,CO,NO2,O3,SO2,CL2,NO,HCL,Temperature,Humidity,Wind
speed,Wind direction,Pressure and other pollutants(expandable) in
the environment. The system pushes the collected data to the
on-site display screen in real time for reference of on-site
personnel, and upload it to the cloud platform of the system. The
platform will conduct big data analysis according to the data
collected from various points, dig out the law of atmospheric
quality change, and provide strong data support for macro control
policies.
