— WHAT IS VACUUM TRANSMITTER CALIBRATION —
Think of a quality lab that relies on a vacuum transmitter 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.
Vacuum Transmitter 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.
— INSTRUMENTS COVERED —
All 6 types · All makes · –1 to 0 bar and high vacuum · NABL accredited
4–20 mA vacuum transmitters for process control and monitoring.
HART-enabled vacuum transmitters for digital diagnostics and configuration.
Low-range absolute pressure transmitters for vacuum process measurement.
Vacuum transducers converting vacuum to electrical signal output.
Pirani gauge controllers with analog output for vacuum system control.
Capacitance-based vacuum transmitters for precision low-pressure measurement.
— OUR PROCESS —
Vacuum transmitter received, tagged. Output type (4–20 mA/HART/voltage), range, and make documented.
Reference vacuum controller applies 0%, 25%, 50%, 75%, 100% FS vacuum. mA/voltage output read. As-found error recorded.
Digital trim via HART communicator or physical potentiometer. Zero at atmosphere (0 vacuum), span at full vacuum.
Ascending and descending 5-point verification. Hysteresis and repeatability per IEC 60770.
Post-trim readings at 5 points confirm compliance. Expanded uncertainty (k=2) calculated. Pass/fail recorded.
NABL CC-2480 certificate with as-found/as-left outputs, uncertainty, IEC 60770/ISO 3529 traceability.

Prism holds NABL CC-2480 under ISO/IEC 17025:2017. Vacuum transmitter certificates accepted by ISO 9001, IATF 16949, GMP/FDA, IBR, PESO, and all audit purposes.
— NON-NABL CALIBRATION —
Routine maintenance calibration without NABL certification — same engineers, same vacuum reference, lower cost.
All calibrations traceable to NPL via vacuum reference — only certificate type differs.
Non-NABL vacuum transmitter jobs faster — ideal for large bulk batches.
Lower cost than NABL — right for utility vacuum transmitters and non-critical systems.
Digital zero and span trim via HART communicator for all smart vacuum transmitters.
— AREAS WE SERVICE —
Onsite vacuum transmitter calibration across all Gujarat with portable references.
