Load Cell Calibration Services

Micro Precision is an ISO/IEC 17025:2017 accredited calibration provider operating a global network of more than 50 labs. Our load cell calibration services deliver NIST-traceable measurement results backed by documented accreditation, serving aerospace, defense, medical device, and manufacturing quality programs with in-lab and on-site service options.

Our load cell calibration services are performed under ISO/IEC 17025:2017 accreditation with NIST-traceable measurement references. Every calibration produces a certificate of calibration documenting as-found and as-left conditions, providing the audit-ready documentation required for ISO 9001, AS9100, FDA 21 CFR Part 820, and other quality management systems.

Our accredited labs calibrate a wide variety of load cell types and capacities, from bench-scale force sensors to high-capacity structural test cells. Industries served include aerospace and defense, medical device manufacturing, automotive production, industrial manufacturing, pharmaceutical, and research and testing laboratories. Our mechanical and dimensional calibration capabilities extend across the full force measurement spectrum, supporting quality programs from incoming inspection through final acceptance testing.

Uncalibrated load cells introduce systematic measurement error into force data, compromising product quality, structural safety, and regulatory documentation. ANSI/NCSL Z540.3 and ISO 10012 require that force measurement instruments used in quality-critical processes be calibrated at defined intervals against traceable standards. Calibration is not optional for operations subject to AS9100, ISO 9001, or FDA quality system requirements.

For quality managers and QA directors, uncalibrated force measurement equipment creates audit findings and compliance gaps that can delay certification or trigger corrective action requests. For lab technicians and metrologists, sensor drift over time invalidates force and weight data unless calibration history is documented and traceable to national measurement standards.

For procurement and compliance teams, selecting an accredited load cell calibration provider ensures that certificates of calibration meet the documentation requirements of third-party auditors, government regulators, and prime contractors across defense, aerospace, and medical device supply chains.

Accurate load cell calibration requires a documented, repeatable process tied to traceable measurement standards. Micro Precision receives each instrument, inspects it for physical condition, applies known force references across the calibration range, adjusts output where necessary, and issues a certificate of calibration documenting as-found and as-left measurement data.

Our calibration process follows these steps for every instrument:

1. Receive and inspect: the instrument is logged, inspected for physical damage, and prepared for testing
2. As-found measurement: the load cell is tested at defined force intervals using NIST-traceable reference standards, and pre-adjustment readings are recorded
3. Adjustment: where readings fall outside acceptable tolerance, the instrument is adjusted to bring output into specification
4. As-left measurement: post-adjustment readings are recorded to document final calibrated performance
5. Documentation: a certificate of calibration is issued with full measurement data, reference standard traceability, and calibration date
6. Return: the calibrated instrument is returned with its certificate of calibration

Standard and rush turnaround options are available. Contact our team when requesting a quote to discuss lead times for your specific load cell type and service level.

Micro Precision offers two load cell calibration delivery modes: in-lab calibration at one of our accredited facilities, and on-site calibration performed at your location by accredited technicians. Both options produce a NIST-traceable certificate of calibration. Rush service is available for time-sensitive calibration requirements.

In-Lab Calibration
Ship your load cells to the nearest Micro Precision accredited calibration facility for service under controlled laboratory conditions. In-lab calibration is suited for portable sensors, bench-scale force transducers, and instruments that can be safely transported without risk of damage or misalignment. Our lab network spans more than 50 locations, keeping transit times and turnaround short.

On-Site Calibration
Micro Precision technicians travel to your facility to calibrate load cells in place. On-site service is the preferred option for permanently installed force measurement systems, high-capacity structural test cells, and platform or floor scale assemblies where removing the sensor creates downtime or re-zeroing risk. Learn more about our on-site calibration services and how to schedule a visit.

Rush Calibration
Rush turnaround is available for production-critical instruments. Request a rush option when submitting your calibration quote to confirm current availability and lead time.
