CPCB-compliant, real-time AQMS solutions with PM2.5 & PM10 sensing, PLC/SCADA integration, and direct data transmission to regulatory servers — engineered for industrial and urban environments across Delhi & NCR.
Drexel Electronics and Engineering Products Pvt. Ltd. is an ISO-certified, MSME-registered manufacturer specialising in real-time environmental monitoring solutions. With over 1,000 successful system installations across India, Drexel delivers end-to-end Ambient Air Quality Monitoring System (AQMS) services — from design and manufacturing to installation, calibration, and after-sales support.
Our systems comply fully with CPCB and SPCB guidelines, transmit live data directly to regulatory servers, and are engineered to withstand demanding industrial environments in Delhi and the broader NCR region.
From continuous ambient monitoring to industrial stack assessment, Drexel offers a complete suite of CPCB-compliant AQMS services tailored to your regulatory and operational needs.
24×7 automated monitoring of outdoor air quality with uninterrupted data logging and direct server transmission to CPCB/SPCB portals. Ideal for industrial zones, smart cities, and pollution hotspots across Delhi NCR.
Drexel provides professional Industrial Air Quality Assessment services for manufacturing plants, power stations, and process industries. Our systems measure multiple pollutants simultaneously, ensuring full compliance with environmental norms.
Fully automated PLC and SCADA-based AQMS installations deliver centralised monitoring, remote diagnostics, alarm management, and historical data analysis — reducing manual intervention and operational costs significantly.
Live sensor data is transmitted via RS-485 or 4–20 mA outputs to remote dashboards, LED scrolling displays, and regulatory portals, giving stakeholders instant visibility into air quality conditions.
Upgrade ageing or non-compliant monitoring infrastructure with Drexel's retrofit solutions. We modernise existing AQMS setups to meet current CPCB standards without requiring a full system replacement.
Drexel offers Annual Maintenance Contracts (AMC), periodic calibration, and dedicated technical support across Delhi to keep your monitoring systems operating accurately and within compliance at all times.
Drexel's dual-channel AQMS analyzer delivers cost-effective, high-accuracy particulate matter monitoring using proven Beta Ray Attenuation technology — certified for CPCB compliance.
