Our equipment
We invest in high-precision reference equipment so your measurements are accurate, traceable and audit-ready — every instrument calibrated in-house against standards traceable to national references.

Pressure reference
Pneumatic & hydraulic reference across low- to high-pressure ranges, with traceable certificates.
Calibrated in-house · traceable to national standards

Electrical reference
Multifunction calibrators & precision meters.

Temperature reference
Dry-blocks, baths & reference thermometers.

On-site · Islandwide
Our engineers bring traceable reference standards to your facility — cutting downtime and the risk of moving fixed or mission-critical instruments. Same accredited result, none of the logistics.
Why Unitest
It comes down to what your auditor and your operation actually need — accredited competence, real traceability, and people who understand the instruments you run.
Independently assessed technical competence to ISO/IEC 17025 — not a generic functional check.
Every result links through an unbroken chain to the SI via Singapore's National Metrology Centre, with stated uncertainty.
Bring instruments to our lab, or have our engineers calibrate on-site to minimise your downtime — islandwide.
A traceable certificate your auditor will accept in ISO 9001, ISO/IEC 17025 and regulated-industry audits.
Backed by 20+ years of instrument expertise and a management team with decades of combined experience.
We remind you when each instrument is due, so nothing quietly drifts out of calibration before your next audit.
Our solutions
One accredited laboratory for your full instrument fleet — in-lab or on-site, with traceable ISO/IEC 17025 certificates.












In the lab
Our laboratory is equipped with well-maintained precision measuring equipment. The standards and instruments used for calibration are regularly checked and proactively maintained to ensure accuracy and consistency — and to identify problems in time.
Our operating procedures and good laboratory practices help us achieve accurate measurement results and issue suitable calibration certificates. Working to ISO/IEC 17025 methods, our reference standards provide sound traceability to recognised national and international standards.
We understand the importance and value of your equipment — which is why our service includes freight transportation.

FAQ
Calibration helps ensure accurate measurements — the foundation of quality, safety and innovation in most of the products and services we depend on daily. Few people realise the vital role calibration plays in everyday life: it underpins the accurate measurements required for research, development and the production of millions of products worldwide. Most of what you see around you is manufactured within strict measurement specifications backed by calibration.
The importance of calibration will keep increasing. As technology advances, measurements need to be more accurate and calibration becomes more critical. Consider self-driving cars: knowing that their precision measurement systems pass the higher level of assurance that calibration offers is exactly what will make future transport systems trustworthy.
The purpose of calibration is to ensure accurate measurements. The benefits include increasing profitability by raising revenue and reducing costs; increasing sales by helping manufacturers and service providers deliver quality products that earn good reviews and loyal customers; and saving money by reducing manufacturing errors and recalls, eliminating wrong acceptances and rejections, and extending the life of manufacturing equipment.
We calibrate
From Fluke and Yokogawa to Druck, Hioki and Extech — we calibrate the instruments your operation already runs, across electrical, temperature, pressure and indoor-air-quality parameters.
