— WHAT IS DIGITAL THERMOMETER CALIBRATION —
Think of a quality lab that relies on a digital thermometer for daily measurements. If it has drifted even slightly from its true value, every reading becomes unreliable — leading to defective products, failed audits, or safety risks. Regular calibration is the only way to confirm your instrument is telling the truth.
Digital Thermometer calibration means comparing its readings against a NABL-traceable certified reference standard at multiple test points, recording the deviations, adjusting where possible, and issuing an NABL certificate — accepted by ISO 9001, IATF 16949, and all quality auditors.
Compare readings against a NABL-traceable reference standard across the full measurement range.
Adjust or document deviations so your instrument reads within accepted tolerance.
Issue a NABL-accredited certificate (CC-2480) with full traceability documentation.

— OUR PROCESS —
Thermometer received and probe/sensor type, cable condition, and display verified. Battery, zero, and display check performed.
Calibration bath or furnace stabilised to first setpoint. Reference standard (SPRT or certified thermometer) inserted alongside unit under calibration.
Temperature comparison at 5 points covering the full range. Units inserted simultaneously. Readings recorded after stabilisation per IEC 60751.
Deviation (error) at each calibration point calculated. Expanded uncertainty computed per GUM framework (k=2).
Measured errors compared to specification. Out-of-tolerance instruments flagged. Correction values provided where applicable.
NABL CC-2480 certificate with temperature data, deviations, uncertainty (k=2), IEC 60751/60584 traceability.

Prism holds NABL CC-2480 under ISO/IEC 17025:2017. Digital thermometer and data logger certificates accepted by pharma validation, WHO-cGMP, USFDA, FSSAI, and ISO 9001 audit bodies.
— NON-NABL CALIBRATION —
For routine maintenance, bulk calibration, or internal QC checks where a full NABL certificate is not mandatory — Prism offers cost-effective non-NABL calibration using the same NABL-traceable reference standards and trained engineers.
All non-NABL work uses NABL-certified reference standards — readings are still reliable and defensible.
Without full NABL documentation, instruments return faster — ideal for urgent production schedules.
Non-NABL calibration costs less — practical for large batches or routine periodic checks.
Available at your facility or at our Vatva lab — same quality, more flexibility.
— AREAS WE SERVICE —
Batch calibration with fast turnaround. Courier pick-up and delivery across Gujarat for pharma, food, and industrial clients.
Why Choose Prism
Since 2004, every NABL thermometer certificate from Prism has been accepted by pharma, food safety, and industrial QMS auditors — no rejections.
