A Calibration Partner Industries Can Rely On

R One Techlabs Private Limited operates two fully equipped calibration laboratories — in Gujarat and Jaipur — with Pan India service coverage. Our processes follow ISO/IEC 17025 standards, meaning every instrument that passes through our lab is measured against national and international references.

We are not a general testing facility. Calibration is our core competency. From temperature loggers in pharma cold chains to pressure gauges on manufacturing floors, we understand the compliance stakes involved in each measurement.

Our NABL accreditation is not a marketing stamp — it's a legal and technical assurance that our calibration results are internationally traceable and audit-ready.

Case Study

Audit Success Through Precision Calibration

Client Challenge
A pharmaceutical company in Ahmedabad required calibration of their cold chain temperature loggers ahead of a WHO-GMP regulatory audit. Non-compliant readings could halt production approvals.
Scope of Work
65 temperature data loggers calibrated across multiple storage ranges, with NABL-traceable certificates for each unit within a 5-day turnaround.
Result
The company passed their WHO-GMP audit without a single calibration-related observation. All 65 logger certificates were accepted by the auditing authority.

Why NABL Matters

NABL Accreditation Is Not Optional

For regulated industries in India, NABL-accredited calibration is increasingly a compliance requirement — not a preference.

Accepted by Regulatory Bodies

NABL accreditation is recognized by BIS, FSSAI, CPCB, DGCA, and international bodies. Your calibration certificates hold up under scrutiny.

Audit Readiness, Always

Whether it's a WHO-GMP visit, ISO 9001 surveillance, or customer quality audit — NABL-calibrated instruments eliminate calibration as a risk area.

International Traceability

Our reports are traceable to national and international standards, accepted in 100+ countries — critical for export-oriented manufacturers.

Measurement Confidence

NABL calibration includes documented uncertainty values — giving you confidence that your measurements are technically defensible.

Using non-accredited calibration in regulated industries risks rejected audits, product recalls, and legal liability. NABL calibration is the only defensible choice.

Frequently Asked Questions

Real Questions from Industrial Clients

Answers based on what our clients actually ask before engaging our calibration services.

What is the difference between NABL and non-NABL calibration?
NABL calibration is performed by laboratories accredited by the National Accreditation Board for Testing and Calibration Laboratories under ISO/IEC 17025. It ensures traceability to national/international standards, documented measurement uncertainty, and regulatory acceptability. Non-NABL calibration lacks this third-party validation and is typically not accepted by regulatory auditors.
Do you provide on-site calibration services across India?
Yes. R One Techlabs offers on-site calibration services across India for instruments that are fixed, delicate, or too numerous to transport. Our field engineers are equipped to perform calibration at your facility with the same NABL-traceable standards used in our labs.
How long does calibration take and what is the turnaround time?
Standard turnaround is 3–7 working days depending on the number and type of instruments. Priority service is available for audit-critical timelines. Our pharma case study involved 65 temperature loggers completed in 5 days with full certification.
Which industries do you primarily serve for instrument calibration?
Our primary sectors include pharmaceuticals, manufacturing, automotive, healthcare, food and beverage, and research laboratories. We have specific experience supporting WHO-GMP, ISO 9001, and BIS compliance audits across these industries.
Are your calibration certificates accepted for WHO-GMP and ISO audits?
Yes. Our NABL-accredited certificates carry international traceability and are accepted by WHO-GMP auditors, ISO certification bodies, BIS, FSSAI, and other regulatory authorities. Multiple clients have successfully cleared audits using our calibration documentation.
