Environmental Testing
Environmental testing services for indoor and outdoor air quality, DG stack emissions, noise, lighting and STP/ETP effluent. On-site monitoring and laboratory testing are available across India, with reports typically delivered within 3–5 working days, depending on the parameters and scope.
Why environmental monitoring matters
Every facility that runs a diesel generator, an STP/ETP, or occupies commercial office space is expected to demonstrate that it isn't degrading the air, noise or water environment around it. Pollution control boards, green building auditors and even employees now ask for current air and emissions data, and a missing or stale report is treated the same as a failed one.
Equinox Labs runs indoor and outdoor air quality assessments, DG stack emission monitoring, data centre corrosion (mixed flowing gas) testing, noise and light quality surveys, and STP/ETP effluent testing at NABL-accredited (ISO/IEC 17025) laboratories, benchmarked against CPCB and applicable state PCB norms. Our field engineers carry calibrated equipment on-site, so monitoring happens under real operating conditions, not simulated ones.

The frequency of DG stack emission monitoring depends on the applicable consent conditions, state pollution control board requirements, generator specifications and site-specific obligations. Check the relevant requirements for your facility to determine the appropriate monitoring schedule.
Yes. We offer indoor air quality testing for offices, hospitals and educational campuses. Depending on the selected testing scope, parameters may include PM2.5, PM10, carbon dioxide (CO2) and volatile organic compounds (VOCs). Testing may also support relevant green building certification documentation, subject to the applicable requirements. See our Indoor Air Quality Testing service for details.
We test STP/ETP effluent against the applicable discharge requirements specified by the relevant pollution control authority and consent conditions. Testing can include parameters such as BOD, COD, total suspended solids (TSS), oil and grease, and pH, depending on the required testing scope.
Yes. Our field teams cover 500+ cities pan-India, so multi-site organisations can consolidate monitoring across all locations with one account manager.
