— WHAT IS PROCESS LOOP CALIBRATOR CALIBRATION —
Think of a quality lab that relies on a process loop calibrator 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.
Process Loop Calibrator 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.

4–20 mA loop calibrators for sourcing, simulating, and measuring current loops.
Process calibrators for sourcing and measuring mA signals in process control.
HART loop communicators for configuring HART smart transmitters in the field.
Multifunction process calibrators handling mA, V, TC, RTD, and frequency signals.
Loop current calibrators for precise 4–20 mA loop testing and calibration.
Signal conditioner calibrators for calibrating isolators and signal converters.
— OUR PROCESS —
Calibrator functions (source mA, measure mA, source TC, simulate RTD) identified. Battery, connector, and CJC condition checked.
NABL-traceable reference standards (precision current source/meter and TC simulator) connected to each calibrator function port separately.
Each function (mA source, mA measure, TC source, RTD simulate) calibrated at 5 points (0%, 25%, 50%, 75%, 100% of range).
Cold junction compensation accuracy verified against certified reference at ambient temperature. CJC error and its contribution to TC temperature documented.
Errors for each function calculated. Expanded uncertainty (k=2) per GUM. Certificate lists each function with its calibration data.
NABL CC-2480 multi-function certificate with data for each calibrated function, uncertainty (k=2), IEC 61298 / IEC 60584 traceability.

NABL Accreditation Standard
Prism holds NABL CC-2480 under ISO/IEC 17025:2017. Loop calibrator certificates accepted by pharma validation, WHO-cGMP, USFDA, oil & gas, 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 —
Courier service for process calibrators. Typical 1–2 day turnaround. Fast digital certificate delivery.
Why Choose Prism
Since 2004, every NABL loop calibrator certificate from Prism has been accepted by pharma, process, and oil & gas audit bodies — no rejections.
