NABL-Accredited Testing Laboratory in India
Environmental, Water, food and pharmaceutical analysis — from one accredited laboratory serving industry across India since 1997.
When a test report has to stand up to a Pollution Control Board, an FSSAI audit, a customer specification or your own quality decision, the laboratory behind it matters. The HECS Laboratory Division delivers chemical, biological and analytical testing under ISO/IEC 17025:2017, backed by advanced instrumentation and technical teams who understand the regulatory and process context behind every number.
What does the HECS laboratory do?
The HECS laboratory is a NABL-accredited, multi-vertical testing facility in India that analyses water, wastewater, air, soil, food and related samples to measure quality and confirm compliance with Indian standards and regulatory limits. Operating from a ~10,000 sq ft laboratory in Chennai since 1997, it serves industrial and service-sector clients across India and international markets — issuing test reports used for regulatory submissions, quality control and environmental management.
In practice: you tell us what needs testing and why — a consent condition, an ETP/STP outlet, a drinking-water panel, a food or product specification, a baseline study — and our team scopes the correct parameters, runs them on validated methods, and issues a report you can rely on and defend.

If your operation holds — or is applying for — a Consent to Establish or Consent to Operate, periodic testing is almost certainly a condition of that consent.
How to choose a testing laboratory in India
Not every lab that says “NABL” holds the scope you actually need. Before you commit, check:
1.Accreditation scope — is your specific parameter/matrix inside the lab's NABL scope, not just “NABL accredited” in general?
2. Instrumentation — can they run trace metals (ICP-MS/AAS) and organics (GC-MS/MS, LC-MS/MS, and HPLC) in-house, or do they outsource?
3.Sampling capability — can they collect representative samples correctly? Sampling errors invalidate good analysis.
4.Regulatory acceptance — are their reports routinely used for CPCB/SPCB/FSSAI submissions?
5.Chain of custody & documentation — proper sample tracking and defensible reporting.
6.Turnaround — realistic timelines that fit your compliance deadlines.
7.Technical support — can they help you interpret results and act on them?
HECS is built to answer “yes” across this list — accredited chemical and biological scope, a broad in-house instrument base, field sampling, and engineers who can advise on what the results mean for your operation.

NABL accreditation and FSSAI recognition serve different purposes. NABL accreditation demonstrates that a laboratory has been assessed against ISO/IEC 17025 requirements for specific testing activities. FSSAI recognition or notification relates to acceptance within the food safety regulatory framework for applicable food testing activities. A laboratory's accreditation and recognition should always be checked against the specific test, matrix and current scope required.
When selecting an environmental testing laboratory, check whether the laboratory's NABL scope covers your specific parameter and sample matrix. Also consider sampling capability, analytical instrumentation, testing methods, quality systems, sample traceability, turnaround time and experience with regulatory monitoring. For compliance work, confirm that the laboratory can provide the exact testing and documentation required by your applicable authority or consent condition.
To request a testing quotation from HECS, provide details such as the sample type, testing purpose, location, required parameters, number of samples and reporting requirements. For environmental compliance, sharing the applicable CTE/CTO condition or regulatory requirement can help the laboratory identify the appropriate testing scope.
