−13%SIRC — Industrial measurement, testing, inspection & calibration

Measurement you can defend to an auditor
Traceable certificates, as-found and as-left values, and recall reminders before your instruments fall due.

An in-house laboratory, not a middleman
Electrical, temperature and pressure calibration performed here — with stated uncertainty and a named reference standard on every certificate.

Instruments chosen by engineers who use them
Fluke, Megger, Testo, Hioki and Yokogawa — specified, supplied and calibrated by the same team.

Laboratory & Calibration Services
Certified testing, inspection, and instrument calibration adhering to international metrology standards with unbroken traceability.

Calibration
Electrical, temperature and pressure instruments calibrated against traceable references, with as-found and as-left values on every certificate.

Inspection
Thermographic surveys of switchgear and motors under representative load, with findings ranked by severity and timescale.

Instrument fleet management
Your whole fleet on one calibration schedule, with recall reminders, collection and delivery, and a single annual contract instead of dozens of purchase orders.

Testing
Earth resistance, insulation and continuity testing with certified reports for compliance and insurance records.

Thermographic survey
Infrared survey of switchgear, motors and terminations under representative load, with every anomaly ranked by severity and a recommended timescale.

Power generation, pharmaceuticals, textile mills, and engineering plants nationwide.
What Engineering Teams Say About SIRC
“Certificates that satisfy the auditor.”
Their certificates carry as-found values, which is exactly what our auditor asks for. We stopped having to explain ourselves at every inspection.
Engineering Insights & Guides
Practical guidance on calibration cycles, ISO compliance standards, instrument selection, and field testing best practices.
CalibrationHow often should your instruments be calibrated?
Twelve months is a convention, not a rule. The right interval comes from drift, duty and what a wrong reading costs.
QualityHow to read a calibration certificate
A pass stamp tells you almost nothing. Here is what to look for — and which omissions should worry you.
InspectionThermographic surveys: what a good one looks like
A hot spot without a load figure is not a finding. What to ask for before you book a thermal survey.
