Common Questions About Environmental Monitoring

For full CPCB compliance, industries typically need to monitor PM2.5, PM10, NOx, SOx, CO, and meteorological parameters (wind speed, direction, temperature, humidity). Specific requirements vary by industry type, facility scale, and location. Our team conducts a detailed regulatory audit to identify your exact compliance obligations.
Current CPCB guidelines mandate automatic data transmission at 15-minute intervals to the designated pollution control board server. Drexel systems use secure SIM/LAN-based cloud gateways with authentication and validation protocols, ensuring uninterrupted, tamper-proof data delivery.
A standard single-station ambient air quality monitoring system installation takes 7–10 working days, including site preparation, equipment mounting, network setup, calibration, and CPCB server integration. Multi-site or complex network deployments are planned with detailed project timelines agreed upon in advance.
Yes. Our comprehensive AMC packages include scheduled preventive maintenance visits, NIST-traceable calibration services, genuine spare part replacement, software updates, and 24/7 technical helpdesk support — ensuring maximum uptime and continuous regulatory compliance throughout the system's operational life.
Absolutely. Drexel offers system retrofit services including sensor replacement, PLC/SCADA software upgrades, CPCB data gateway integration, and compliance enhancements for legacy monitoring systems — extending equipment life while ensuring current regulatory compliance.
Our solutions serve manufacturing and industrial facilities, thermal power plants, pharmaceuticals and chemical processing, textile and dyeing units, healthcare and biomedical waste operators, construction sites, government and municipal bodies, IT parks, smart city projects, and transportation infrastructure across India and internationally.
