— WHAT IS TEMPERATURE CALIBRATION —
Think of it like a doctor's thermometer that hasn't been checked in years. If it reads 98°F but the real temperature is 101°F, the wrong decision gets made. In a factory, the same problem happens — if a furnace thermocouple reads 200°C but the actual temperature is 215°C, your product quality fails or your process becomes unsafe.
Temperature calibration means checking your thermocouple, RTD, or thermometer against an accurate reference, correcting any error, and giving you an NABL certificate as proof — accepted by ISO, FDA, and GPCB auditors.
Safety
A drifted thermocouple in a furnace or boiler can cause overheating, fires, or product damage.
Quality
Pharma, food, and chemical processes need exact temperatures. Wrong readings = failed batches.
Compliance
FDA, ISO 9001, and WHO GMP all require calibration records. The NABL certificate is that proof.
Cost Saving
Finding sensor drift early prevents batch failures, product recalls, and unplanned shutdowns.

— OUR PROCESS —
Every temperature calibration follows our documented ISO/IEC 17025 procedure — traceable, repeatable, auditable.
Temperature instrument received and tagged. Range, type, make, model, serial noted. Condition documented.
Instrument placed in calibrated dry block or liquid bath at defined temperature points. As-found readings recorded across full range.
Readings compared against NPL-traceable reference SPRT or PRT. Error calculated at each point per ITS-90 temperature scale.
Offset, slope, or curve correction applied where possible. Smart transmitters adjusted via HART communicator. Correction table issued if needed.
Post-adjustment readings verified at all calibration points. Expanded uncertainty calculated per ISO/IEC 17025. Pass/fail recorded.
NABL CC-2480 certificate with as-found/as-left data, uncertainty, and full ITS-90 traceability. Digital delivery within 24 hours.

— NON-NABL CALIBRATION —
For instruments not requiring NABL certification — routine maintenance checks or bulk calibration — Prism provides cost-effective non-NABL temperature calibration with the same trained engineers and traceable reference standards.
All calibrations use NPL/BIPM-traceable reference standards regardless of NABL or non-NABL certificate.
Non-NABL jobs completed faster — ideal for urgent maintenance, breakdowns, or bulk batch calibration.
Non-NABL calibration priced lower — right choice for internal or non-audit use cases.
Available at our Ahmedabad lab and as onsite service across Gujarat — with or without NABL.
