How our Ahmedabad lab works with you.

Every engagement follows the same disciplined steps, so results are consistent and audit-ready.

  2. 02

    Plan the work

    We agree dates, on-site or in-lab handling and the protocol to follow, so production and QA know exactly what will happen and when.

  3. 03

    Measure with traceable standards

    Qualified engineers carry out the work using calibrated reference instruments traceable to national standards, recording raw data as they go.

  4. 04

FREQUENTLY ASKED

Questions, answered.

Can’t find what you need? Call +91 63579 03105 or email calibration@kesartesting.com.

How often should calibration and validation be performed?

It depends on regulatory requirements, how critical the equipment is and how heavily it is used. Calibration is usually done annually or at the interval set in your SOPs. Cleanrooms and critical equipment are typically revalidated annually, and again after major maintenance or changes.

Do you provide on-site calibration and validation?

Yes. We calibrate many instruments at your facility to avoid downtime and shipping risk, and handle other instruments in our Ahmedabad laboratory. Cleanroom and HVAC validation is always carried out on-site.

Which regions do you cover?

We serve clients across India from our laboratory in Vatva GIDC, Ahmedabad, including Gujarat, Maharashtra, Delhi NCR, Karnataka, Telangana, Andhra Pradesh, Madhya Pradesh, Goa and Himachal Pradesh.

Is Kesar Testing Service LLP NABL accredited?

Yes. We are accredited by NABL to ISO/IEC 17025:2017 in the field of calibration (certificate CC-4388, valid until 1 May 2029). We have held NABL accreditation since 2018, and you can verify our scope on the NABL website.

What documentation will we receive?

Calibration certificates show measured values, measurement uncertainty and traceability to national standards. Validation reports include the protocol, raw data, results against acceptance criteria and the calibration certificates of the instruments we used.
