Industramach is also one of the pioneer companies that offered ambient air sampling services way back in year 1995.  As a local partner to a US-company, IMACH was selected by DENR/Environmental Management Bureau to rehabilitate, operate and maintain the Metro Manila Air Quality Monitoring Network consisting of 10 Ambient Air Monitoring Stations in year 2004 to 2006.  In compliance with the Republic Act No. 8729 or the Philippine Clean Air Act, the whole network aimed to provide air quality assured data for different criteria pollutants such as SO2, NO2, CO, THC, O3, TSP, Pb, PM2.5 and PM10.  Likewise, the network was capable of monitoring non-criteria pollutants, i.e. Benzene, Toluene and Xylene.
