Your Trusted Light Meter Calibration Provider
Micro Precision is an ISO/IEC 17025:2017 accredited light meter calibration provider offering NIST-traceable calibration across a network of 50+ calibration labs. Quality managers, lab technicians, and procurement teams in manufacturing, workplace-safety-driven industries, construction, and automotive rely on Micro Precision to keep lux meters, foot-candle meters, and illuminance meters within specification and ready for audit.
Micro Precision’s ISO/IEC 17025:2017 accreditation and NIST-traceable calibration process establish a documented chain of measurement traceability for light meters, giving quality teams the evidence auditors expect during compliance reviews. This accreditation is verified through accredited scope documents available on request, and every calibration is backed by a certificate of calibration.
Micro Precision calibrates a variety of light meter types, including digital lux meters, foot-candle meters, and illuminance meters used across workplace lighting audits, photographic exposure verification, and general quality inspection. Each calibration includes ISO/IEC 17025:2017 accredited testing and traceable documentation, whether equipment is serviced in-lab or on-site.
Why Light Meter Calibration Matters
Uncalibrated light meters create workplace safety compliance gaps and lighting quality-control errors that can affect OSHA-driven lighting audits, photographic color and exposure accuracy, and manufacturing inspection standards. Light meter calibration performed to ANSI/NCSL Z540.3 requirements keeps measurement results defensible during audits and reduces the risk of non-conforming lighting assessments.
Quality managers depend on documented light meter calibration to demonstrate that lighting-level readings used in safety audits and process inspections are traceable and defensible. Procurement officers rely on consistent calibration intervals and NIST-traceable results to select and retain reliable calibration vendors without renegotiating trust on every order.
Light meter calibration performed to ANSI/NCSL Z540.3 requirements, with NIST-traceable results and ISO/IEC 17025:2017 accredited methods, gives compliance officers documented evidence that lighting measurements used in workplace safety and quality-control decisions meet recognized calibration standards. Without regular calibration, drift in a light meter’s readings can go undetected, creating gaps in safety documentation and inspection records that surface during an audit.
Ensure Accurate Light Meter Calibration
Micro Precision ensures accurate light meter calibration through a structured process: receive the instrument, inspect it for physical and functional condition, test it against NIST-traceable reference standards, adjust it as needed, document all results, and return it with a certificate of calibration. This process applies consistently across lux meters, foot-candle meters, and illuminance meters.
Every light meter calibration is performed under ISO/IEC 17025:2017 accredited procedures, and results are recorded on a certificate of calibration that documents traceability back to NIST. This documentation supports internal quality records and external audits alike.
Every light meter returned by Micro Precision includes a certificate of calibration documenting NIST-traceable results, ISO/IEC 17025:2017 accredited test methods, and the as-received and as-returned condition of the instrument, supporting both internal quality records and third-party audits. Micro Precision offers standard and faster turnaround options for light meter calibration, so quality teams can align scheduling with production deadlines or audit timelines without compromising documentation quality.
Our Calibration Options
Micro Precision offers both in-lab and on-site light meter calibration, giving quality teams flexibility based on equipment mobility, production schedules, and facility access requirements. In-lab calibration provides access to a full range of NIST-traceable reference standards, while on-site calibration reduces equipment downtime for light meters that are difficult to remove from service.
Both calibration options are performed under ISO/IEC 17025:2017 accredited procedures and include a certificate of calibration documenting NIST-traceable results. Micro Precision provides in-lab and on-site light meter calibration options, backed by ISO/IEC 17025:2017 accreditation and NIST traceability, so quality teams can choose the service model that best fits equipment mobility and facility constraints.
Standard and faster turnaround options are available for both in-lab and on-site light meter calibration. Procurement officers can request faster turnaround when audit deadlines or production schedules require quicker completion, without sacrificing NIST-traceable documentation or ISO/IEC 17025:2017 accredited test methods.

Frequently Asked Questions
Most light meters require calibration annually, with quarterly or biannual intervals recommended for high-accuracy or regulated environments. Light meters should also be recalibrated immediately after being dropped, exposed to extreme temperature or humidity, or showing inconsistent readings. Micro Precision documents recommended intervals on every certificate of calibration issued under ISO/IEC 17025:2017 accredited procedures.
Light meter calibration compares the instrument’s readings against a NIST-traceable reference light source under controlled conditions, then adjusts the meter to match the known standard. Micro Precision performs this process under ISO/IEC 17025:2017 accredited methods, documenting results on a certificate of calibration before returning the instrument.
Light meter calibration cost varies based on meter type, service level, and whether calibration is performed in-lab or on-site. Micro Precision provides a calibration quote for each light meter based on these factors rather than a fixed published price. Request a calibration quote for exact pricing on a specific model.
NIST-traceable light meter calibration means the meter’s readings are verified against reference standards with a documented, unbroken chain of comparisons back to the National Institute of Standards and Technology. Micro Precision provides NIST-traceable light meter calibration under ISO/IEC 17025:2017 accredited procedures, with traceability documented on every certificate of calibration.
Yes. Micro Precision provides on-site light meter calibration for facilities that need to avoid removing equipment from service. On-site calibration follows the same ISO/IEC 17025:2017 accredited procedures and NIST-traceable methods used in-lab, and results are documented on a certificate of calibration returned after service.
A lux meter is a type of light meter that measures illuminance specifically in lux units, while the broader term light meter includes lux meters, foot-candle meters, and photographic exposure meters. Micro Precision calibrates a variety of light meters, including lux meters, under ISO/IEC 17025:2017 accredited procedures.
