Engineering across air, stack, process and weather
AESST Technologies delivers the full lifecycle of environmental monitoring and industrial instrumentation — AQMS, CEMS, process analyzers, meteorological networks, data acquisition and the turnkey engineering services that hold them together. Every system is designed for regulatory compliance, audit-grade data and operational uptime in the harshest sites.
Environmental Monitoring

AQMS — Continuous Ambient Air Quality Monitoring
Reference-grade ambient air quality monitoring stations engineered for regulatory compliance, citywide networks and industrial fenceline programs.
AESST AQMS shelters integrate USEPA-equivalent analyzers, meteorological sensors and a hardened data acquisition stack inside a climate-controlled enclosure. Every station is delivered with auto zero/span calibration, NIST-traceable gas standards, dynamic dilution calibrators and direct CPCB CARE Air integration — sized to your siting study and ready for third-party audits from day one.

CEMS — Continuous Emission Monitoring Systems
Extractive and in-situ CEMS engineered for CPCB Phase III compliance, refinery flares, power plant stacks and waste-to-energy lines.
We deliver heated extractive sample probes (180 °C), heated sample lines, sample conditioning cabinets, NDIR / UV-DOAS / FTIR / chemiluminescence analyzer racks and isokinetic particulate monitors — wired into a redundant DAS that streams validated data to regulators and your plant historian. Every CEMS train is pre-engineered to the stack matrix, gas composition, dew point and ambient envelope.

Water Quality & Effluent Monitoring
Online and laboratory water quality monitoring across drinking, surface, ground, marine, ETP and STP streams — engineered for CPCB OCEMS, MoEFCC and SPCB compliance.
AESST supplies and integrates online water quality analyzers for pH, conductivity, dissolved oxygen, turbidity, TSS, TDS, BOD, COD, TOC, ammonia, nitrate, nitrite, phosphate, oil-in-water and heavy metals. Skid-mounted analyzer cabinets, auto-cleaning probes, sample handling and 4G-enabled DAS push validated data straight to SPCB / CPCB servers and plant historians.

Meteorological Monitoring & Dispersion
WMO-grade meteorological masts, sensors and dispersion modelling support for industrial siting, airports, mines and renewable energy.
10 m, 30 m and tilt-up masts pre-engineered with ultrasonic and cup anemometers, wind vanes, RTD temperature, humidity, barometric pressure, solar radiation and tipping-bucket rain sensors — wired to a 4G data logger. The same data feeds dispersion modelling (AERMOD, CALPUFF) for siting and consent applications.
Process & Industrial

Process Instrumentation & Control
Field instruments, analyzer houses and control systems for refineries, petrochemicals, power, cement, steel and water treatment.
From a single Coriolis flow meter to a full analyzer house with PLC / DCS integration, AESST engineers, supplies and commissions process instrumentation rated for hazardous areas (IECEx, ATEX) and aggressive process conditions. We cover sensor selection, sizing, calibration, loop checks, SAT/FAT documentation and operator training.

Process Analytical Solutions
Process gas chromatography, online analyzers, sample-conditioning systems and analyzer shelters for refineries, petrochemicals, hydrogen, biogas and combustion processes.
Distinct from environmental monitoring, AESST's Process Analytical division engineers in-line and at-line analytics for process optimisation — natural-gas GCs, hydrogen / syngas / biogas analyzers, oxygen and CO/CO₂ combustion analytics, moisture and dewpoint, TDLAS for trace species, plus the full sample-conditioning system, analyzer shelter and DCS integration that turns a reading into closed-loop control.
Laboratory Analytical

Laboratory Analytical Solutions
Laboratory-grade analytical instruments and method development for R&D, QA/QC, environmental and pharma laboratories — GC, GC-MS, HPLC, ICP-OES, ICP-MS, FTIR, UV-Vis and TOC.
AESST supplies and supports laboratory analytical instrumentation with full method development, validation, AMC and training — gas chromatography (GC, GC-MS, GC-FID/TCD/ECD), liquid chromatography (HPLC, UHPLC), ICP-OES and ICP-MS for elemental analysis, FTIR and UV-Visible spectroscopy, TOC, moisture and particle analyzers — plus laboratory automation and ISO 17025 documentation packages.
Turnkey engineering, built around your plant
One accountable engineering partner across siting, EPC, calibration, AMC, software and modernization — so your monitoring systems stay compliant and online for their full lifecycle.

Site Survey & Engineering
CPCB-aligned siting studies, stack assessments, civil and utility planning, plus AERMOD / CALPUFF dispersion modelling before a single bolt is set.
Installation & Commissioning
End-to-end EPC across mechanical erection, power and signal cabling, cold and hot commissioning, FAT/SAT and CPCB API integration.
Calibration Services
On-site multi-point calibration with NIST / NPL traceable gases, linearity audits, cylinder management and signed certificates.
Preventive Maintenance & AMC
Comprehensive and non-comprehensive AMC tiers with SLA-backed response, 24×7 helpdesk, consumable stocking and uptime guarantees.
Data Acquisition & Software
Edge data loggers, SCADA bridges, cloud dashboards, validated reporting and secure transmission to CPCB CARE Air and customer historians.
System Upgradation & Retrofits
Modernize legacy stations with new analyzers, loggers, protocol upgrades, cyber hardening and migration to current compliance standards.
