Trust & Accreditation
Our SAC-SINGLAS Accreditation (ISO/IEC 17025)
Unitest Instruments holds SAC-SINGLAS accreditation to ISO/IEC 17025 under Accreditation No. LA-2023-0845-C. Our calibration certificates carry recognised measurement traceability and are accepted by auditors and regulators in Singapore and worldwide.
What it means
Why accreditation is the signal your auditor looks for
A “calibration certificate” from a non-accredited provider may not satisfy your audit, because nothing independent vouches for that provider's competence, methods or measurement uncertainty. SAC-SINGLAS accreditation is that independent proof — assessed against ISO/IEC 17025.
Independently assessed technical competence
Traceability to national / international standards
Defined measurement uncertainty
Recognised in ISO 9001 / 17025 audits
Accreditations & accolades
Three independent marks of competence, safety & trust
As an ISO/IEC 17025:2017 accredited laboratory, Unitest is committed to continually improving service quality, data quality and laboratory effectiveness — and our quality management system is regularly re-evaluated by third-party auditors to keep that technical competence current.

Our commitment to precision — and to safety
At Unitest, accreditation isn't a badge on the wall — it's how we prove the number on every certificate can be trusted. Two independent standards govern how we work: ISO/IEC 17025:2017 for the quality of our measurements, and bizSAFE Level 3 for the safety of the people who make them.
Why ISO/IEC 17025:2017 matters
Our laboratory is accredited to ISO/IEC 17025:2017 and re-assessed by third-party auditors — so our competence is verified, not asserted. For you, that means:
- Service quality — every calibration held to a consistent, audited standard.
- Data precision — results whose accuracy and stated uncertainty you can rely on.
- Laboratory effectiveness — methods and competence kept at the level your auditors expect.
The result is peace of mind: certificates that hold up in an ISO 9001 / 17025 audit, every time.
Why bizSAFE Level 3 matters
We hold our workplace to that same discipline. Our bizSAFE Level 3 certification reflects:
- Management commitment — leadership accountable for a safe working environment.
- Continual improvement — safety practices implemented, documented and reviewed, not set-and-forgotten.
- Peace of mind — for your team and ours, on every on-site job.
Choose Unitest and you choose a partner committed to precision, reliability and safety — backed by accreditation, not adjectives. Certificate copies are available on request.
