Factory-tested, CPCB-approved monitoring systems ready for rapid deployment across industries.
The engineering principles that make Drexel systems the most reliable in the field.
Non-optical, in-situ particulate measurement that delivers accurate SPM readings even in extreme high-temperature environments above 95°C – no optical degradation, no maintenance downtime.
Seamless SIM/LAN-based data transmission to CPCB/SPCB servers at 15-minute average frequency with encrypted, redundant communication pathways to ensure zero data loss.
Industrial-grade programmable logic controllers paired with SCADA platforms deliver rock-solid automation, remote control, and real-time supervisory capabilities for any plant scale.
Next-generation sensors with embedded self-diagnostics and predictive maintenance alerts reduce downtime and enable proactive servicing before failures occur.
Multiple concurrent data transmission pathways – primary and fallback channels – guarantee continuous data availability and regulatory compliance even during network disruptions.
Every monitoring solution is configured to match the client's specific site conditions, industry regulations, and performance targets – no one-size-fits-all deployments.
