Why SAC-SINGLAS Accreditation Matters

SAC-SINGLAS is Singapore's national laboratory accreditation body. When a calibration laboratory is SAC-SINGLAS accredited to ISO/IEC 17025, it means the government has independently verified the lab's technical competence, equipment, procedures, and measurement traceability.

Certificates from accredited laboratories are accepted under the ILAC Mutual Recognition Arrangement — covering 100+ countries. This means your calibration results are accepted internationally without re-testing.

Calibration Services FAQs

Common questions about SAC-SINGLAS accredited calibration services in Singapore. Can't find your answer? WhatsApp or email us — we respond within two business hours.

What is SAC-SINGLAS accreditation?

SAC-SINGLAS (Singapore Accreditation Council – Singapore Laboratory Accreditation Scheme) is Singapore's national laboratory accreditation body. Accreditation under SAC-SINGLAS to ISO/IEC 17025 confirms that a calibration laboratory has demonstrated technical competence and measurement traceability to national and international standards. Unitest Instruments holds SAC-SINGLAS accreditation number LA-2023-0845-C, valid to 2 August 2027.

How long does calibration take?

Standard calibration turnaround is 3–5 working days from receipt of instruments, depending on instrument type, quantity, and scope of work. Send us your instrument list and we will confirm the exact schedule when we issue your quotation. Urgent or priority services are available — contact us to discuss.

Do you issue calibration certificates?

Yes. Every calibration performed in our SAC-SINGLAS accredited laboratory is accompanied by an official calibration certificate showing as-found and as-left readings, measurement uncertainty, reference standard traceability, and accreditation details. These certificates are internationally recognised under the ILAC MRA and accepted in ISO 9001, GMP, and other regulatory audits.

What brands and instruments do you calibrate?

We calibrate instruments from all major brands regardless of where they were purchased — including Fluke, Rotronic, Hach, Testo, Extech, Hioki, Yokogawa, Omega, and many others. Our scope covers electrical, temperature, humidity, pressure, and dimensional/torque parameters. Contact us with your specific instrument list and we will confirm scope.

Do you offer on-site calibration in Singapore?

Yes. In addition to our Boon Lay drop-off laboratory, we offer on-site calibration services anywhere in Singapore. Our mobile team brings accredited equipment to your facility — ideal for large fleets, fixed installations, or operations where instrument downtime must be minimised.

Why is calibration to ISO/IEC 17025 important?

ISO/IEC 17025 is the international standard for testing and calibration laboratory competence. A calibration performed by an accredited laboratory provides documented measurement traceability, stated measurement uncertainty, and confidence that your instruments are accurate. Results from non-accredited calibration providers may not be accepted in regulatory audits or export-market inspections.

How often should instruments be calibrated?

Calibration frequency depends on the instrument type, usage intensity, operating environment, and the requirements of your quality management system or regulatory framework. Common intervals range from 6 months to 2 years. Many organisations use the as-found data from each calibration to optimise their recall intervals — a longer interval may be justified if an instrument consistently stays within tolerance.
