Ambient Air Quality Monitoring System
Ambient Air Quality Monitoring System
Mahabal Enviro Engineers offers Ambient Air Quality Monitoring System. This is done to measure the common air that human beings breath anywhere or at workroom environment. The respirable dust sampler (RDS) is modified high volume sampler (HVS) with capability to separate the below 2.5 or 10 micron dust respectively. The design of the RDS has to be developed and certified by the recognised institute. The duration of sampling has to match with the one specified in the standard being used for comparison. Depending on the concentration of various pollutants, the sampling duration may have to be reduced to shorter interval. As such the monitoring may be continued for 24 hours, by changing the absorbing solutions after every 8 hours. Gaseous pollutants are analysed by standard methods in the laboratory. Sampling rate for respirable particulate matter (RPM)/suspended particulate matter (SPM) has to be minimum of 1000 ltr/min and periodic adjustment may have to be done or the filter paper has to be changed at shorter interval. The sampling rate may fall below minimum due to heavy pollution load and therefore clogging of filter paper. The machine requires 230 V supply and the motor is DC type. It is not of flame-proof type and hence precautions are to be taken while sampling in prohibited area. During operation, the noise level is around 65 dB 2 m away from the RDS/HVS sampler.
