Pollution parameter display is used for displaying the concentration of pollutants like dust particles, gases like CO2, CO, NO, NOx etc. Pollution Parameter Displays are used along with AQM systems or dust monitoring sensors or are also available with built in sensors. These sensors are designed for outdoor installations for sensing above parameters. These displays are available as • Numeric displays with parameter names in vinyl stickers • Alphanumeric displays with fixed or scrolling parameter names and values. These displays are used outside the plants for showing the pollution level in the ambient air due to plant exhausts, in construction sites showing dust concentration in the ambient air and in cities and towns for monitoring air pollution.
